From Install to JS Testing

To install on Symfony 5, I needed to fork the following four repos and update their composer.json files to allow Symfony 5 packages:

- Fork behat/mink
- Fork behat/mink-extension
- Fork behat/symfony2-extension
- Fork friends-of-behat/symfony-extension (remove package-builder conflict declaration)

My installation steps are:


symfony composer update
symfony composer req behat/behat:dev-master --dev
symfony composer req behat/mink:dev-master --dev
symfony composer req behat/mink-extension:dev-master --dev
symfony composer req behat/symfony2-extension:dev-master --dev
symfony composer req friends-of-behat/symfony-extension:dev-master --dev
vendor/bin/behat
symfony composer req phpunit --dev


The demo feature file works with the above setup but I've not gone beyond that point as I type this.

Hey Ronald,

Thank you for sharing the version that works for you. Yeah, with latest version it works not perfect. I'd recommend you to try to use Google Chrome instead of Firefox, it might work better with Behat nowadays.

Cheers!

I had the same problems with running Selenium in Docker. When I limited the version of selenium/standalone-firefox to 2.53.1 the tests went through. Seems like the Mink Selenium drivers have trouble with newer browser/Selenium versions. Not that surprising considering the last stable version is from 2016. The development versions didn't work either.

The strange thing is, that when i ran behat with the -v parameter it actually showed the correct html.

Hey Gonzalo,

Hm, I don't know how it works internally, but we do use Docker containers on our CircleCI and it just works. As I understand, our base containers is "php" ( https://hub.docker.com/_/php ) and our Selenium containers is "selenium/standalone-chrome" ( https://hub.docker.com/r/se... ). So, I know little about Docker, but these two just work for us, though not sure what's done behind the scene of it. What Selenium container do you use? Try to use this one. I suppose, you just need to forward some ports, i.e. make them explicit and accessible from the Selenium container to your host machine, or maybe for your PHP containers instead, not sure.

As a workaround, I suppose you can just install the Selenium server manually on your PHP container and spin up it,

I hope this helps!

Cheers!

How to use it with docker, I have initialized a container with selenium, but I can't connect it with another container that has the php application inside. Any ideas?

Is your web-server running? Also, remember that you need to start chrome and selenium in case you are using it

Cheers!

Hey RAJAONA Ywoumé

Try installing behat/[email protected] it's not recommended to install the dev-master branch but in this case they don't give us other option until they add compatibility with Symfony4 and since it's a dev dependency there is no much risk being taken

Cheers!

Hey Virginie Burlot!

I get that :p.

> I don't know if I will go for Behat, PHPUnit, or phpscpec. I'm following your course on PHPUnit at this time, and will folliow with the one on phpscpec next. I liked how you user Behat on the REST API courses though.

PHPUnit will be your easiest option if you want to implement tests on your API. That's simply because it's the "lowest-level" tool - there's no BDD or magic at all, which has some negatives, but also lowers the barrier to entry. Using Behat is probably the highest barrier to entry with the API stuff (even though it's fun to use it). A middle-ground would probably be to use PHPUnit, but in a BDD kind of way. You wouldn't have feature files or scenarios (sadly), but you still could think of each test class as a "feature" and each method as a "scenario" (and you could even name that method in a descriptive way to show what "thing" you're API user is actually trying to accomplish in that test). By building a base "test class" with your own helper methods, you can also help make your tests more descriptive - e.g. instead of something like $client->request('POST', '/login'), you would say $this->login(), which is shorter... but also more descriptive.

Anyways, take that advice or leave it - it's all up to what you want and "can" take on :).

Cheers!

Thank you for your answer.
I actually passed on this part of the course. I just watched it, and not practiced it.

I'm studying different testing technology because I have a big project coming up (a big API which will replace an old webapp), and I don't need to know how to test JS for this one.

I don't have the time to use more than one technology. I barely have the time to implement one, but I prefer to be late for a "good" reason, than on time and discovering flaws afterwards.
I don't know if I will go for Behat, PHPUnit, or phpscpec. I'm following your course on PHPUnit at this time, and will folliow with the one on phpscpec next. I liked how you user Behat on the REST API courses though.

I will try again later, when I could, to make Mink work correctly, and I will try your suggestions. :)

Hey Virginie Burlot!

Sorry for my slow reply! This is exactly when this type of testing gets tricky... because when something doesn't work... you're thinking "But why? What's missing?". One of my favorite debugging techniques is the "I break" technique shown here: https://symfonycasts.com/sc...

This will "freeze" the browser right before it fails... which sometimes can be useful to see what's going wrong - e.g. you discover that the button you're trying to click is missing or there's an error on the page (things that are difficult to spot if the page just disappears immediately when it fails). I might also try commenting-out this line and seeing if the NEXT line works or also fails.

Let me know what you find out! You could definitely also skip this part, and see if things start working in a bit. Overall, this *could* be a browser/driver setup issue... or just some other problem (like an error on the page, for example). The first type is a bit harder to debug :/.

Cheers!

Hi !

I have an issue while running the scenario with the @javascript option (the same one as Leora had a year ago) :

Feature: Search
In order to find products dinosaurs love
As a web user
I need to be able to search for products


@javascript
Scenario: Searching for a product that exists # features\search.feature:7
Given I am on "/" # FeatureContext::visit()
When I fill in "searchTerm" with "Samsung" # FeatureContext::fillField()
Form field with id|name|label|value|placeholder "searchTerm" not found. (Behat\Mink\Exception\ElementNotFoundException)
And I press "search_submit" # FeatureContext::pressButton()
Then I should see "Samsung Galaxy" # FeatureContext::assertPageContainsText()


--- Scénarios échoués:


features\search.feature:7


1 scénario (1 échecs)
4 étapes (1 succès, 1 échecs, 2 ignorés)
0m6.74s (12.29Mb)


I've read every comment here. I have the same issue on Firefox or Chrome, for the first one, I've installed GeckoDriver, then I saw the last note, I installed ChromeDriver, and use the browser_name in my behat.yml. My Selenium Server is started.
I have no issue without the @javascript option.

Do I have to have everything working here to pursue on this course ? I'm most of the time working on APIs and back-end, I will probably, not in the near future, need to run tests on JS on front-end for that matter. I will need to work on a big API, and I'm really looking forward BDD.

I'm really not familiar with these tools, I may have made mistake while installing everything.

Hey Nigel,

Wow, that's complex! Glad you found a solution that kinda fits you, and thanks for sharing it with others! Good luck with it!

P.S. Good plan about sending a PR later ;)

Cheers!

Hi Victor,

Ultimately extending Selenium2Driver didn't work for me; as you said copying the the whole Selenium2Driver code into the extending class is bad practice and just extending the class does not grant access to the private methods or variables.

So what I finally did was create a Selenium2DriverDecorator:

From FeatureContext I create a new decorator:

    private function getDecoratedDriver(): Selenium2DriverDecorator
    {
        return new Selenium2DriverDecorator($this->getSession()->getDriver());
    }

In the Selenium2DriverDecorator constructor I assign the driver to a private property:

class Selenium2DriverDecorator

    private $driver;

    public function __construct(DriverInterface $driver)
    {
        $this->driver = $driver;
    }

And then access methods and properties irrespective of their visibility via the __call and __get magic methods.

 

    public function __call($methodName, $args)
    {
        $driver = $this->driver;
        $closure = function (DriverInterface $driver) use ($methodName, $args) {
            return $driver->$methodName(...$args);
        };

        $closure = Closure::bind($closure, null, $driver);

        return $closure($driver);
    }

    public function __get($name)
    {
        $driver = $this->driver;
        $closure = function (DriverInterface $driver) use ($name) {
            return $driver->$name;
        };
        $closure = Closure::bind($closure, null, $driver);

        return $closure($this->driver);
    }

This allows me to treat the decorator as if it was the driver itself which makes the code more readable:

And I can achieve what I set out to do (simulate "dragenter" and "dragleave" events):

    public function simulateEventAfterDragstart(
           string $event, 
           string $sourceXpath, 
           string $destinationXpath): void
    {
        $source = $this->findElement($sourceXpath);
        $destination = $this->findElement($destinationXpath);

        $this->wdSession->moveto(array(
            'element' => $source->getID()
        ));

        $script = $this->getSimpleEventScript('dragstart');

        $this->withSyn();
        $this->executeJsOnElement($source, $script);


        $script = $this->getSimpleEventScript($event);
        $this->withSyn();
        $this->executeJsOnElement($destination, $script);
    }

    private function getSimpleEventScript($event): string
    {
        return <<<JS_HEREDOC
            (function (element) {
                var event = document.createEvent("HTMLEvents");
            
                event.initEvent("$event", true, true);
                event.dataTransfer = {};
            
                element.dispatchEvent(event);
            }({{ELEMENT}}));
JS_HEREDOC;
    }

It took me a while but I think that this is the best solution.

When I've got all the functionality I need I will suggest updates for the GitHub repository.

Kind regards,

Nigel

Hey Nigel,

Thank you for sharing your solution with others! Yes, it looks like you extended it correct, I don't see any other way to do it. Well, you can hack things by copy/paste that file to your project and do necessary changes in it, but it will be dirty, and this way you won't have updates from the library :/ So, your way is much more intelligent, but as you see it has some limitations.

I don't know why exactly you need to extend that Selenium2Driver, but if you think there's a bug or a missing feature - I'd recommend you to open an issue in its repository: https://github.com/minkphp/... - this should be the correct one. You can discuss your idea there, and maybe open a PR to implement it if people will agree on it.

Cheers!

So,

I realised that even if I could extend Behat\Mink\Driver\Selenium2Driver it would fail because there are so many private methods that the extending class would not have access to.

So I changed behat.yml to include this:

default:
    extensions:
        App\Tests\Behat\MinkExtension\ServiceContainer\CustomMinkExtension:
            browser_name: chrome
            base_url: http://theatre.localhost
            javascript_session: selenium2e
            goutte: ~
            selenium2e: ~

I extended MinkExtension:

class CustomMinkExtension extends MinkExtension
{
    public function __construct()
    {
        $this->registerDriverFactory(new ExtendedSelenium2Factory());
        MinkExtension::__construct();
    }
}

I extended Selenium2Factory:

class ExtendedSelenium2Factory extends Selenium2Factory

getDriverName return 'selenium2e';

buildDriver (array $config) to build ExtendedSelenium2Driver instead of Selenium2Driver 

and

Just copied the whole of Selenium2Driver into ExtendedSelenium2Driver and worked from there.

I think that this is the only way?

Kind regards,

Nigel

Hi Ryan,

I'd like to extend Behat\Mink\Driver\Selenium2Driver so that I can add a few methods and still have access to the public and protected methods that the class offers.

Is there a way to achieve this in behat.yml?

I'm using Symfony 4 and in my behat.yml I have:

default:
    extensions:
        Behat\MinkExtension:
            browser_name: chrome
            base_url: http://theatre.localhost
            javascript_session: selenium2
            goutte: ~
            selenium2: ~
        Behat\Symfony2Extension:
            kernel:
                bootstrap: features/bootstrap/bootstrap.php
                class: App\Kernel
    suites:
        default:
            contexts:
                - FeatureContext:
                        kernel: '@kernel'
                - DebugContext
                - Behat\MinkExtension\Context\MinkContext

I came up with this to execute private methods on the driver but it's messy:

public function executeMethodOnDriver($driver, $methodName, ...$params)
    {
        $closure = function (Selenium2Driver $driver) use ($methodName, $params) {
            return $driver->$methodName(...$params);
        };

        $closure = Closure::bind($closure, null, $driver);

        return $closure($driver);
    }

for example:

  /**
     * @Given I test xpath
     */
    public function iTestXpath()
    {
        $driver = $this->getSession()->getDriver();
        $xpath = '//div[contains(@class, "address")]';
        $source = $this->executeMethodOnDriver($driver, 'findElement', $xpath);
    }

I suppose I could extend RawMinkContext and then use __call as a proxy to executeMethodOnDriver.

Kind regards,

Nigel

Hey Marwen Ben Ahmed

I believe you still have to install behat/mink library. Give it a try and let me know if it works

Cheers!

hello friends,
when i run command ./vendor/bin/behat i show this issue :
Mink instance has not been set on Mink context class. Have you enabled the Mink Extension? (RuntimeException)

and my behat.yml file has this content :

default:
  extensions:
    Behat\MinkExtension:
      browser_name: chrome
      base_url: https://front.manewco.lo
      goutte: ~
      selenium2: ~

and my package.json has this code :

"require-dev": {
        "behat/behat": "^3.5",
        "behat/mink-extension": "^2.3",
        "behat/mink-goutte-driver": "^1.2",
        "behat/mink-selenium2-driver": "^1.3",
        "behat/symfony2-extension": "^2.1",}

any idea of this bug please ???
thank's ....

Hey Carlos Eduardo!

Hmm, that errors comes from using the "selenium" driver - but we need to use the selenium2 driver in this tutorial. Double-check that you have "selenium2: ~" in your behat.yml file and not just "selenium: ~".

Cheers!

Why am i getting ...
[RuntimeException]
Install MinkSeleniumDriver in order to activate selenium session.

?

Hey Murad

That goes far beyond the scope of this tutorial but after watching it and understanding how Behat works, you will feel more confident on doing it by yourself.

Cheers!

Hey Murad

You firstly have to install and setup a Selenium server and install ChromeDriver, after that you only have to add this config to your behat.yml file:

default:   
  extensions:
    Behat\MinkExtension:
      ...
      javascript_session: selenium2
      selenium2:
        capabilities:
          chrome:
            switches: ['disable-popup-blocking']

Probably this gist may help you out a bit more: https://gist.github.com/jk/...

Cheers!

Hey Murad!

So, the SnippetAcceptingContext was deprecated, but it has not been removed from Behat yet - so it *should* work. I would recommend either re-adding it, or using the "--snippets-for" option that Victor mentioned above.

Btw, don't use ContextSnippetGenerator - I don't know where you found that - but it has a totally different purpose :).

You said earlier:

> What I can use instead of SnippetAcceptingContext ? Because it is not working any more

What do you mean by it not working anymore? Do you run Behat but the snippets are not added to your class? Or do you get an error? Give us as much information as possible to help :).

Cheers!

How this framework can be converted into page object model?

Hi Viktor, you've done a great job. But I think there are compatibility issues between extensions. My framework is working with goutte driver but not with selenium. Selenium2Extension is also not working. Could you describe how a framework can be created as a new project from scratch? How can I downgrade symfony 4 to the version that can work with extensions used for test automation. Thank you.

Hey Murad,

This tutorial is still relevant. If you have any problems, please, ask in comments and we would try to help you to figure out the problem. If the problem in this tutorial, we would be happy to add some notes to it to help other users avoid hitting problems. What do you think should be updated here? Or why do you think this tutorial should be updated? We would be glad to your feedback with more detailed info!

Cheers!

I think this tutorial should be updated

I used
use Behat\Behat\Context\Snippet\Generator\ContextSnippetGenerator;

But when I'm implementing that one as here below
class LoginContext extends RawMinkContext implements Context, ContextSnippetGenerator

phpStorm asks interface reference

Hey Murad,

From the docs https://firefox-source-docs... :
> Selenium users must update to version 3.11 or later to use geckodriver. Other clients that follow the W3C WebDriver specification are also supported.

Here's the page where you can find more info how to install it: https://firefox-source-docs... . As you can see, you can find an installation file from releases on GitHub, for example: https://github.com/mozilla/...

If you're on a Mac and use Brew - I think you can easily install it as "brew install geckodriver".

I hope this helps!

Cheers!

Hey Murad,

Instead of SnippetAcceptingContext I see you can use "--snippets-for", see deprecation message:
https://github.com/Behat/Be...

Cheers!

Hey Murad,

I does not mean Composer dependencies. Please, try to reinstall chrome driver in your OS. Btw, do you have chromedriver installed in your OS?

Cheers!

How can I install geckodriver for Selenium 3 version?

And What I can use instead of SnippetAcceptingContext ?
Because it is not working any more

Hey Murad,

Hm, difficult to say.... try to re-install the chrome driver, on the internet I see it should help with this kind of error. If not, you can try to switch to the Firefox browser.

Cheers!

Hi, I have this error when trying to run feature file:

Could you help to initialize the browser? Thank you

Hey Sergey,

Unfortunately, behat/mink package does not have a release for Symfony 4, see: https://github.com/minkphp/... . The only workaround to install it for now is to use master branch for it, like:
1. composer req behat/mink:dev-master
2. composer req behat/mink-extension

Or wait until a new behat/mink release that will support Symfony 4

Cheers!

Hi there!

Can I change that restriction somehow? Could you give any advice how to install it on Symfony 4.2?

Hey Luis Mas!

We may, but we don't currently have any immediate plans to do so. However, we would be happy to answer any questions you have!

Cheers!

Hi, are you going to update it to Symfony 4?

Thanks!

Ohh, so that was the problem, I'm glad to hear that you could fix your problem :)
Cheers!

I installed the last version of chromedriver - then it worked. (I also had to install homebrew and follow those instructions as well). Finally passed!

No, I copied the search.feature straight from the text on the course page. When I specify Chrome as the browser in behat.yml, I get a slightly different error message:
When I fill in "searchTerm" with "Samsung" # FeatureContext::fillField()
unknown error: call function result missing 'value'
(Session info: chrome=69.0.3497.92)
(Driver info: chromedriver=2.31.488774 (7e15618d1bf16df8bf0ecf2914ed1964a387ba0b),platform=Mac OS X 10.13.6 x86_64) (WebDriver\Exception\UnknownError)

Hey Leora Wenger sorry for the late response. Hmm, so you are actually hitting your homepage, try to find any other element on that page, just to be sure that everything is working correctly.
What I believe is that you don't have any form field named "searchTerm" (remember that IT is case sensitive)

Wow, that was a long response (still get the error under) - there is more, but it won't let me post all, too long:

Hmm I think it should just work. Add the step And print last response after step "Given I am on "/" "
let's see what's returning

(formatting got removed when I posted the behat.yml file)

default:
    extensions:
        Behat\MinkExtension:
            base_url: http://localhost:8000
            goutte: ~
            selenium2: ~

Interesting... so probably your configuration is not correct. Can you show me your behat.yml file please

Diego, I have both Selenium server running as well as Chrome, and I still get that error message.

Hey Leora Wenger

In order to use "@javascript tag" you need to start your selenium server first and probably a browser as well, it depends on your local environment.

Cheers!

Hi, I am getting an error on the "searchTerm" section when using Selenium. I did not get this error when @javascript is not in the search.feature file:

Hey Mr. ß ,

Have you installed that geckodriver as we mentioned in this chapter? Also, are you trying to use Firefox? Could you try to use Google Chrome instead? I really had a bad experience using Selenium with Firefox lately.

Cheers!

Hi,

Whenever I tried to run behat, I get this error. My search.feature looks like:

Can you please help me?

Hey Daka
When you create a step automatically via Behat console, it adds you a "pending" check line code, what it does is to throw a custom exception which you haven't added the import. You can just remove it, or add the import by yourself

Have a nice day

Thank you Victor, I will give that a go

Hm, I was experienced a few weird things with Firefox. Could you try to use Google Chrome instead? I bet it'll fix your problem. IIRC, Firefox is just not ready to the latest Behat / Selenium server. The other things: your deps and version of selenium server - look good for me.

Cheers!

Browser if Firefox,
Here is a snippet from my composer.json

I am using selenium-server-standalone-3.7.1.jar

Then I should see "Suppliers" comes from the video You can see it at 4:43

Thanks
Simon

Hey Simon,

Your scenario looks fine, which browser you run this scenario in? Google Chrome or Firefox? What's your version of Behat and what's your version of Selenium server? I think you just have some problems with compatibility, probably simple upgrade of selenium server could fix the problem.

Also, where's the "I should see..." step definition comes from? Is it from Behat core?

Cheers!

Using Windows 10 and Symfony 3.3. I have the following scenario

Feature: Supplier
  In order to be able to work with suppliers
  As a web user
  I need to be able to see a list of suppliers

  @javascript
  Scenario: Listing all suppliers
    Given I am on "/suppliers"
    Then I should see "Suppliers"

When I run Behat, The browser opens and I quickly see the page before it closes, then I get the following error

 @javascript
  Scenario: Listing all suppliers # features\suppliers.feature:6
    Given I am on "/suppliers"    # FeatureContext::visit()

Hey Thierno,

Hm, "getId() === getId()" is a bad thing to do. Do you implement \Serializable interface, i.e. do you have serialize()/unserialize() methods in your User entity or parent classes which this entity extends? Could you make sure you serialize/unserialize fields correctly, i.e. you have the same fields number and its order in both methods? Probably you could debug where exactly it fails in default Symfony\Component\Security\Core\User\UserChecker (if you do not override it)?

Cheers!

Hi weaver i am using guard but when a user logged in he is automatically log out here is the message in the log : The security token was removed due to an AccountStatusException.
But it works when i implement the Symfony\Component\Security\Core\User\EquatableInterface like this :
public function isEqualTo(UserInterface $user)

{

return $user->getId() === $this->getId();

}

but i don't think this is normal.
Help please.

Yo Pawel!

Hmm. It looks like an issue with Selenium: https://github.com/Selenium.... This happens from time-to-time: as browsers make updates, Selenium needs to be updated to work with those browser changes. So, unfortunately, you will see issues like this occasionally - they're often fixed in the next version of Selenium. I would try a different browser for now, to see if you have better luck.

Cheers!

I put `selenium-server-standalone-3.4.0.jar` and `geckodriver` in my root project dir. I got error: `Exception thrown
org.openqa.selenium.UnsupportedCommandException: mouseMoveTo`.
I am using:
Geckodriver v0.18.0
Firefox 54
Linux Mint 18.2

Hey Evgeniy,

Hm, are we talking about "BDD, Behat, Mink and other Wonderful Things" course? Probably if you did not have SQLite extension - you would have a huge error about it. I think the same is for permissions problem, so that's weird. Are you sure you do not see any errors in your terminal after "php app/console doctrine:database:create" command execution? What is your output? You should see something like:

> ~/Downloads/behat/finish: $ app/console doctrine:database:create
> Created database ~/Downloads/behat/finish/app/app.db for connection named default.

Is it the same for you? Could you paste it here?

Anyway, I just double checked it: Downloaded the course code, went to the finish/ directory. installed Composer dependencies and run "php app/console doctrine:database:create" - and it works for me fine.

Cheers!

Thanks for answer. But after command: php app/console doctrine:database:create no misstake but DB does not creating (( And "app/app.db" database file doesn"t create .... Why?

Hey Евгений,

That's not a full Symfony Standard Edition, just some kind of micro app based on Symfony components. This project doesn't have any parameters.yml and parameters.yml.dist files. For simplicity, all the configuration happens in app/config.yml - you can see:

doctrine:
    dbal:
        driver:   pdo_sqlite
        path:     %kernel.root_dir%/app.db

So as you can see we use SQLite DB for this course, and after you run that commands from README file you will have "app/app.db" database file. So try to run those commands and make sure the app.db file is created. Of course, feel free to change driver to "pdo_mysql" if you want to use MySQL instead, but then you also need to set up its credentials under the "doctrine.dbal" key in config.yml.

Cheers!

Hi! I'm having trouble trying to load up DB. In README file after step 2 (composer install) I try to load DB by running stack of command: php app/console doctrine:database:create
php app/console doctrine:schema:update --force
php app/console doctrine:fixtures:load But in app/config I have no parameters,yml or parameters.yml.dist .... how can DB loading in this case ? README file says after running stack of commands above I must receive `app/app.db` file. But I havn"t app.db file. I cant run php app/console doctrine:database:create command Can you help me or explain what i miss?

You already answered this for yourself in another thread, but I want to answer it here in case for others :). This tutorial is currently about an old bundle - in version 2.8 Guard was accepted into core (yay!) and now works a bit differently. You can find a screencast about this in our Symfony security tutorial: http://knpuniversity.com/sc...

Cheers!

Hi everyone!

I'm having this problem Viral had before, but I'm with this fancy Symfony 3.2.8 and I tried to follow the steps.

Here is the output I got when I try to run my application

InvalidConfigurationException in ArrayNode.php line 317:
Unrecognized option "knpu_guard" under "security.firewalls.main"

I'm missing something ?

Thanks in advance!

Hey UnkRec,

No, you don't have - Guard component installed out-of-the-box, so just you can start using it. This tutorial is still current, but in some places we have notes if something was changed/renamed - just skip installation section if you're on Symfony 2.8 or higher.

Cheers!

Do we have to install Guard via composer if using the latest version of Symfony 3 (to date)?
How much of this " KnpUGuard: Symfony Authentication with a Smile Tutorial" is current?

That's a great idea - I've gotten this question several times! I'll add it to our idea list :). In short, one approach would be have 2 authenticators. When the first (e.g. something that checks username/password) is successful, instead of *actually* being successful, set something on the session, and then fail authentication (e.g. by returning false in getCredentials()). In onAuthenticationError, if that session value exists, instead of sending them back to the login page, redirect to some other URL (where the 2nd factor is checked). On that URL, add the form for the 2nd authentication. Have a 2nd authenticator handle the submit: it would check that the session value from the first is present (to make sure someone didn't skip to this step) and then process as normal. You might also need a listener that redirects to the 2nd factor page for for ALL other URLs once that session token is set (i.e. once the first factor has been successful).

It's honestly not something I've ever tried. It's one of those problems that's not technically *that* hard to solve (after all, it's just 2 different forms), but I'm not convinced that the above method is all that smooth, or the smoothest possible.

Cheers!

Be nice to see an article on how to add two factor authentication using guard. I'm trying to play around with it but nothing concrete yet.

Thanks for sharing the link! And yea, I know what you mean - Behat docs are a bit light on some setup details... which is a shame, because it's SO rewarding to work with afterwards :). Happy you got there!

FYI, I found this article on Gecko webdrivers super handy:

http://michalzalecki.com/se...

Also also, thanks so much for this course. I've been meaning to get round to learning Behat properly for months and I've always had set up problems. This is the first place I've found that explains how to get started properly.

Sweet! So happy that worked - and thank you for the follow-up! Awesome!

Bingo! Worked a treat, thanks Ryan. I downloaded the Mac archive from https://github.com/mozilla/..., unzipped it, put the executable in my project root (though I guess it could have gone anywhere, and might more sensibly be kept somewhere like /usr/local/share or something.

As you described, I added the path to the executable to my path, and now I can run tests with Selenium.

Thanks again for your help!

Hey James!

Yea, Selenium is temporarily in a weird place right now as they've recently released their 3.0 version of the server, which has some differences with how the old one works. As I understand it, you need to also download the gecko-driver in order to use Firefox (https://github.com/mozilla/... or the Chrome driver to use Chrome (https://github.com/mozilla/.... I *think* that you just need to make sure these are in your path (i.e. that you can just say chromedriver from the command line) - I don't *think* that you actually need to run them manually. I'm doing a lot of "think" because, while I have the new Selenium 3 server running on my machine, I had the chrome-driver installed a long time ago, so I'm not 100% positive what I might have done with my setup way back then.

Anyways, let me know if downloading gecko-driver helps. Otherwise, we'll find the solution. I think we may need a note on this tutorial about the new setup steps with Selenium.

Cheers and apologies for the inconvenience with Selenium!

Hey - I'm having a little bit of trouble with the Selenium part of this tutorial. I can run the scenario without Selenium, but when I try to do it using the @javascript option, Selenium opens up a Firefox window then just hangs. After a while I get a message saying:

Could not open connection: Unable to connect to host 127.0.0.1 on port 7055 after 45000 ms.

...followed by a load of console output from Firefox that I don't really understand.

Any suggestions for what to do next would be much appreciated.

Yes, that helped a lot and I have it up and running now.

Hey Tom,

Ah, yes, this course have not been completely released yet. Take a look at "knpuniversity/oauth2-client-bundle" bundle, it helps a lot with OAuth2. BTW, it has some examples how to integrate this bundle with Symfony Guard: https://github.com/knpunive... . Let us know if you have any questions about integration.

Cheers!

Anyone figured out how to do Facebook / Google / OAuth with this bundle? It's my main reason to come here and then it says "coming soon" ... :-/

Ah, great news!

I notify the owner of the server about the problem and he fixed it buy setting varnish Thx a lot

Yea, I agree that it sounds like a session-saving issue. But since you say that you *can* see session files created, and that they are created on each request, then it makes me wonder if Varnish is stripping the cookies so that each request (to Symfony) looks like a fresh request (i.e. one that has no cookie). I would remove Varnish, at least to test, and see if that fixes the problem.

Cheers!

No i did that dump to verify if the session was working i asked to the owner of the server he tell me that he installed varnish and since i juste replaced a project who was on the server with mine i mean its the same domain i think that is the problem

The PHPSESSID does not store in cookies for this domain. You can see it in Google Chrome Developer Tool. I think it's because you have a dump statement in DefaultController.php on line 17. Please, remove it and check again.

My hostname is senegeek.com so i think thats not the problem

One possible cause for this is having a host name without a domain part (.com, .org, etc.), e.g. http://example/ instead of http://example.com/

Thx for your response
Session are saved in the folder var/sessions but the problem is that for every request it create one file in the session folder

Hey Thierno,

You should configure session properly - most likely session can't be stored on your server. Where do you store session? If it stores in files - look at save_path option and ensure you setup permissions for it correctly on the server. Let me know if it helps.

Cheers!

Hi Ryan i have a probleme with the guard authentication I use symfony 3.1 in my project the guard authentication work fine in my local machine but when i deploy to the server if the authentication succed i am redirecting to the home page but i loose the authentication and become anonymous again.
I set a session variable to show it in another page but it turn that the variable was deleted .
So i think that the session is deleted every request but i dont know why.
Really need help Thx

Hey ciudadano82 ,

You don't have to install GuardBundle for Symfony 3.1 because Guard Component provides with Symfony out of the box since Symfony 2.8, so just start using it without installation! :)

Check this blog post page for more information: http://symfony.com/blog/new... .

Cheers!
