Cheatsheet for End to End Tests

Generating Data

When filling out forms you probably want to use the generators.

 $el['.t-field_first_name']->setValue($this->generate('name:first'));

There is some overlap in assertions between methods of ClientTestCase and methods on Mink's WebAssert class, but the former always uses css selectors, so it's a little less verbose.

Working with NodeElement objects

<?php

class Test {

  public function testExample() {

    // By using getDomElements we ensure only one of .t-link.
    $el = $this->loadPageByUrl('/node/9750')
      ->getDomElements([
        '.t-link',
      ]);

    // $el['.t-link'] is an instance of NodeElement.
    $el['.t-link']->click();

    // Altenatively you could do this.  But it will not break if there is
    // more than one '.t-link' on the page. So it's less certain.
    $this->el('.t-link')->click()
      }

}

Making Assertions with Mink

Load a page and then make assertions using Mink's WebAssert class.

<?php

class Test {

  public function testExample() {
    $this->loadPageByUrl('/node/9750')
      ->assert()
      ->elementTextContains('css', '#button', 'English');

    $this->assert()
      ->elementTextContains('css', '#button-2', 'Spanish');
  }

}
