Modern PHP Testing for everyone

Codeception is a modern full-stack testing framework for PHP. Inspired by BDD, it provides you an absolutely new way of writing acceptance, functional and even unit tests. Powered by PHPUnit.

Bugfixes should be sent to to current stable branch, which is the same as major version number. Breaking features and major improvements should be sent into master. When you send PRs to master, they will be added to release cycle only when the next stable branch is started.

Check also the "tests/" to learn more about the available internal Codeception tests.


The documentation for each module is directly generated from the corresponding docblock which can be found in each module (src/Module/Codeception/*.php).

At a Glance

Describe what you test and how you test it. Use PHP to write descriptions faster.

Run tests and see what actions were taken and what results were seen.

Sample acceptance test


$I = new FunctionalTester($scenario);
$I->wantTo('create wiki page');
$I->see('New Page');
$I->submitForm('form#new_page', array('title' => 'Tree of Life Movie Review','body' => "Next time don't let Hollywood create art-house!"));
$I->see('page created'); // notice generated
$I->see('Tree of Life Movie Review','h1'); // head of page of is our title
$I->seeInCurrentUrl('pages/tree-of-life-movie-review'); // slug is generated
$I->seeInDatabase('pages', array('title' => 'Tree of Life Movie Review')); // data is stored in database

For unit testing you can stay on classic PHPUnit tests, as Codeception can run them too.
