Finding inside HTML Tables

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
... lines 1 - 27
Then the "Foo1" row should have a check mark
... 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:

231 lines features/bootstrap/FeatureContext.php
... lines 1 - 118
/**
* @Then the :rowText row should have a check mark
*/
public function theProductRowShouldShowAsPublished($rowText)
{
... lines 124 - 127
}
... 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():

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

231 lines features/bootstrap/FeatureContext.php
... lines 1 - 124
assertNotNull($row, 'Cannot find a table row with this text!');
... lines 126 - 231

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

231 lines features/bootstrap/FeatureContext.php
... lines 1 - 126
assertContains('fa-check', $row->getHtml(), 'Could not find the fa-check element in the row!');
... lines 128 - 231

Moment of truth:

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

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

    Thanks Diego.

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

    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!

    Hahaha, don't worry! It happens to all of us, I preffer to don't talk about the dummy things I've done :p

    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"

    Thanks very much... it was a stupid one!

    Keep up the good work

    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!

    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.
