Here is an effort at documenting Drupal testing patterns from what's currently used in core tests. The objective is to promote reusability of standardized patterns throughout core and contributed tests.
// Catch - this looks good, but I think we should completely ignore stuff like getContent() which is used once per year and just focus one what 70% of basic tests will use - the API docs etc. are there, and linkable at the end, for everything else.
Browser-related patterns
Fetch a page (GET)
<?php
// Fetch an URL in the internal browser (GET).
$this->drupalGet($url);
?>Known shortcomings:
- There is no documented way to tweak headers
Fetch a page (other methods)
drupalHead() is meant to fetch headers via the HEAD method.
<?php
// Fetch an URL in the internal browser (HEAD).
$this->drupalHead($url);
?>Known shortcomings:
- The sames as
drupalGet()above, - There is no generic way (yet) to get content via other HTTP methods.
Post a form
<?php
$edit = array('name' => $name, 'mail' => $mail);
$this->drupalPost('user/register', $edit, t('Create new account'));
?>Default values defined by the form will be used if not overriden in $edit.
Known shortcomings:
- There is no way to target a specific form on the page (by its
$form_id). - It is not possible to get default values of fields already defined on the page before posting the form.
Post a form: upload a file
From upload.test:
<?php
$edit = array(
'files[upload]' => $filename
);
$this->drupalPost('node/' . $nid . '/edit', $edit, t('Save'));
?>Known shortcomings:
- When you upload a file, it is impossible to have any other field starting with a '@' (cURL shortcoming).
Assert content on a page
<?php
// assertRaw checks for raw HTML in the page the internal browser last fetched.
$this->drupalGet('user/register');
$this->assertRaw('<a href="'. url('user/password') .'">', t('Make sure a link appears to "Request new password" on the user register page.'));
// assertText checks for plain text in the page the internal browser last fetched.
$this->drupalGet('user/register');
$this->assertText(t('Request new password'), t('Make sure the text "Request new password" appears on the user register page.'));
?>Follow a link
<?php
// TODO: find a real life example
$this->clickLink($label, $index = 0);
?>Get the content of the internal browser
<?php
// Get the response content.
$content = $this->getContent();
?>
