To finish the scenario, we need a Then that's able to look for a check mark on a specific row. The check mark icon itself is an element with a fa fa-check class.

There is no built in definition to find elements inside of a specific row. So let's describe this using natural language. How about:

43 lines | features/web/product_admin.feature

Show Lines	// ... lines 1 - 27
	Then the "Foo1" row should have a check mark
Show Lines	// ... lines 29 - 43

Execute Behat to get that definition printed out for us:

./vendor/bin/behat features/product_admin.feature:21

When you're feeling really lazy, you can add a --append-snippets flag and Behat will put the definitions inside of the FeatureContext class for you:

./vendor/bin/behat features/product_admin.feature:21 --append-snippets

Change arg1 to be rowText:

            Copy Code

                            Show All Lines

                        231 lines
            |
            features/bootstrap/FeatureContext.php
        
                Show Lines

                                                    // ... lines 1 - 118
                            
                /**
        
                 * @Then the :rowText row should have a check mark
        
                 */
        
                public function theProductRowShouldShowAsPublished($rowText)
        
                {
        
                Show Lines

                                                    // ... lines 124 - 127
                            
                }
        
                Show Lines

                                                    // ... lines 129 - 231

Ok, this is a bit harder. First, we need to find a row that contains that $rowText and then look inside of just that element to see if it has a fa-check class in it.

Start by finding via CSS, $row = $this->getPage()->find('css'). For the selector, use table tr: and then the contains pseudo selector that looks for some text inside. Pass %s and set the value using sprintf():

            Copy Code

                            Show All Lines

                        231 lines
            |
            features/bootstrap/FeatureContext.php
        
                Show Lines

                                                    // ... lines 1 - 123
                            
                    $row = $this->getPage()->find('css', sprintf('table tr:contains("%s")', $rowText));
        
                Show Lines

                                                    // ... lines 125 - 231

$row will now be the first tr containing this text, or null. It's not perfect: if $rowText had some bad characters in it, the selector would fail. But this is my test so I'll be lazy until I can't. Add assertNotNull() function:

            Copy Code

                            Show All Lines

                        231 lines
            |
            features/bootstrap/FeatureContext.php
        
                Show Lines

                                                    // ... lines 1 - 124
                            
                    assertNotNull($row, 'Cannot find a table row with this text!');
        
                Show Lines

                                                    // ... lines 126 - 231

Finally, assert that the row's HTML has a fa-check class inside of it with assertContains():

            Copy Code

                            Show All Lines

                        231 lines
            |
            features/bootstrap/FeatureContext.php
        
                Show Lines

                                                    // ... lines 1 - 126
                            
                    assertContains('fa-check', $row->getHtml(), 'Could not find the fa-check element in the row!');
        
                Show Lines

                                                    // ... lines 128 - 231

Moment of truth:

./vendor/bin/behat features/product_admin.feature:21

We're green! Now, let's get even harder.

Hello and thank you for this screencast. It's really superb and helpful.

So i'm having difficulties with this feature... finding the fa check in the row. I'm just getting Fatal error: Call to undefined function assertNotNull() in /Users/...

Any idea why? I have PHPUnit installed, so i've obviously missed something stupid?

Thanks in advance.
Jon

Hey Jon!

I think you forgot to require PHPUnit assert functions library, just add this line to the top of your Context class (Adjust the path to your needs)
require_once __DIR__.'/../../../vendor/phpunit/phpunit/src/Framework/Assert/Functions.php';

Have a nice day!

Hi Diego,
probably I had another stupid question but I can't find the answer so maybe you can help me. What about when I'm using PHPUnit Bridge (v5.0) and I want use asserts in behat.I found that the path to asserts functions is in other directory (not in vendor dir but in bin), but when I try to require it with new path
<br />require_once __DIR__.'/../../bin/.phpunit/phpunit-7.5-0/src/Framework/Assert/Functions.php';<br />
or by using namespaces
<br />use PHPUnit\Framework\Assert;<br />
I still get an error
<blockquote>
Fatal error: Class 'PHPUnit\Framework\Assert' not found (Behat\Testwork\Call\Exception\FatalThrowableError)
</blockquote>

Thanks a lot for any help.

Hey Cristóbal Rejdych

It's not a stupid question at all, actually, you hit a pesky bug! Check at this thread https://github.com/symfony/...

TL-DR If you need to work with PHPUnit directly, you will have to install that depedency ignoring the warnings coming from Symfony PHPUnitBridge

Cheers!

Hey Diego ;)
First of all thanks for quick reply. Yeah I saw this page before when I looked for solution, but that guy was talking about component called codeception which looks for me like another library to making tests. I was thinking about install PHPUnit and leave PHPUnitBridge too but it looks like duplication of code and I was affraid to break PHPUnitBridge. So that what I supposed to do? Just install PHPUnit without remove anything and ignore warnings?
Cheers!

Ah, yes, he got this same problem but when working with Codeception, the work around it's the same, just install PHPUnit and ignore the warning :)

On a separate note... can Behat / PHPUnit assert some text in a cell in a row containing some text, but also based of the what column the cell is in

e.g.

Adapting Then I should see (the text ):text in the :rowText row
.... with Then I should see (the text ):text in the :rowText row in the Column called "column4"

Hey Jon!

That's totally possible with the find method, using CSS selector, brings you all you can do with normal CSS, so you could do something like this:


$row = $this->getSession()->getPage()->find('css', sprintf('tr:contains("%s")', $rowText));

$td = $row->find('css', sprintf('td:nth-child(%s)', $columnNumber));
        
assertEquals($text, $td->getText());

I didn't test it (it should work), but it should give you an idea of what can you do :)

Have a nice day!

Thanks Diego.

I wasn't able to get it working today, but i'll keep trying

This tutorial uses a very old version of Symfony. The fundamentals of Behat are still valid, but integration with Symfony will be different.
