CakePHP module for Codeception

CakePHP 3 Codeception Module

A codeception module to test your CakePHP 3 powered application. Using Codeception with CakePHP opens up a whole new set of testing capabilities.

Front-end testing

(i.e. browser-based workflow tests)

• [Functional Tests]
  • does the App run the way we expect
• [Acceptance Tests]
  • does the App do what the customer/user expects

Back-end testing

(i.e. direct, internal method tests)

• [API Tests]
  • does the App's API work
• [Unit Tests]
  • do the App's internal functions do what we expect

Usage

From a CakePHP application, run the following from the command-line:

$ composer require --dev cakephp/codeception:dev-master && composer run-script post-install-cmd

If you are developing a plugin, add the post-install script to your composer.json first:

{
    "scripts": {
        "post-install-cmd": "Cake\\Codeception\\Console\\Installer::customizeCodeceptionBinary"
    }
}

Once installed, you can now run bootstrap which will create all the codeception required files in your application:

$ vendor/bin/codecept bootstrap

This creates the following files/folders in your app directory:

├── codeception.yml
├── src
│   └── TestSuite
│       └── Codeception
|           ├── AcceptanceTester.php
|           ├── FunctionalTester.php
|           ├── UnitTester.php
|           ├── Helper
│           │   ├── Acceptance.php
│           │   ├── Functional.php
│           │   └── Unit.php
|           └── _generated
|               └── .gitignore
└── tests
    ├── Acceptance.suite.yml
    ├── Functional.suite.yml
    ├── Unit.suite.yml
    ├── Acceptance
    │   └── bootstrap.php
    ├── Fixture
    │   └── dump.sql
    ├── Functional
    │   └── bootstrap.php
    └── Unit
        └── bootstrap.php

As you might have noticed, the CakePHP implementation differs in a couple things:

• uses CamelCase suite names (Functional vs. functional)
• uses bootstrap.php, no underscore prefix (vs. _bootstrap.php)
• uses src/TestSuite/Codeception for custom modules (helpers) (vs. tests/_helpers)
• uses tmp/tests to store logs (vs. tests/_logs)
• uses tests/Fixture to fixture data (vs. tests/_data)
• uses tests/Envs to fixture data (vs. tests/_envs)
• adds a .gitignore to never track auto-generated files
• adds custom templates for various generated files using the codecept binary

To better understand how Codeception tests work, please check the official documentation.

Example Cept

<?php
$I = new FunctionalTester($scenario);
$I->wantTo('ensure that adding a bookmark works');
$I->amOnPage('/bookmarks/add');
$I->see('Submit');
$I->submitForm('#add', [
    'title' => 'First bookmark',
]);
$I->seeInSession([
    'Flash'
]);

Actions

Auth

...

Config

Assert config key(/value) with seeInConfig($key, $value = null)

$I->seeInConfig('App.name'); // checks only that the key exists
$I->seeInConfig('App.name', 'CakePHP');
$I->seeInConfig(['App.name' => 'CakePHP']);

Assert no config key(/value) with dontSeeInConfig($key, $value = null)

$I->dontSeeInConfig('App.name'); // checks only that the key does not exist
$I->dontSeeInConfig('App.name', 'CakePHP');
$I->dontSeeInConfig(['App.name' => 'CakePHP']);

Db

Insert record with haveRecord($model, $data = [])

This is useful when you need a record for just one test (temporary fixture). It does not assert anything and returns the inserted record's ID.

$I->haveRecord('users', ['email' => '[email protected]', 'username' => 'jadb']);

Retrieve record with grabRecord($model, $conditions = [])

This is a wrapper around the Cake\ORM\Table::find('first') method.

$I->grabRecord('users', ['id' => '1']);

Assert record exists with seeRecord($model, $conditions = [])

This checks that the requested record does exist in the database.

$I->seeRecord('users', ['username' => 'jadb']);

Assert record does not exist with dontSeeRecord($model, $conditions = [])

This checks that the request record does not exist in the database.

$I->dontSeeRecord('users', ['email' => '[email protected]']);

Miscellaneous

Load fixtures

In your Cest test case, write $fixutures property:

class AwesomeCest
{
    public $fixtures = [
        'app.users',
        'app.posts',
    ];

    // ...
}

You can use $autoFixtures, $dropTables property, and loadFixtures() method:

class AwesomeCest
{
    public $autoFixtures = false;
    public $dropTables = false;
    public $fixtures = [
        'app.users',
        'app.posts',
    ];

    public function tryYourSenario($I)
    {
        // load fixtures manually
        $I->loadFixtures('Users', 'Posts');
        // or load all fixtures
        $I->loadFixtures();
        // ...
    }
}

In your Cept test case, use $I->useFixtures() and $I->loadFixtures():

$I = new FunctionalTester($scenario);

// You should call `useFixtures` before `loadFixtures`
$I->useFixtures('app.users', 'app.posts');
// Then load fixtures manually
$I->loadFixtures('Users', 'Posts');
// or load all fixtures
$I->loadFixtures();

Assert CakePHP version with expectedCakePHPVersion($ver, $operator = 'ge')

$I->expectedCakePHPVersion('3.0.4');

Router

Open page by route with amOnRoute($route, $params = [])

All the below forms are equivalent:

$I->amOnRoute(['controller' => 'Posts', 'action' => 'add']);
$I->amOnRoute('addPost'); // assuming there is a route named `addPost`

Open page by action with amOnAction($action, $params = [])

All the below forms are equivalent:

$I->amOnAction('Posts@add');
$I->amOnAction('Posts.add');
$I->amOnAction('PostsController@add');
$I->amOnAction('PostsController.add');
$I->amOnAction('posts@add');
$I->amOnAction('posts.add');

Assert URL matches route with seeCurrentRouteIs($route, $params = [])

All the below forms are equivalent:

$I->seeCurrentRouteIs(['controller' => 'Posts', 'action' => 'add']);
$I->seeCurrentRouteIs('addPost'); // assuming there is a route named `addPost`

Assert URL matches action with seeCurrentActionIs($action, $params = [])

All the below forms are equivalent:

$I->seeCurrentActionIs('Posts@add');
$I->seeCurrentActionIs('Posts.add');
$I->seeCurrentActionIs('PostsController@add');
$I->seeCurrentActionIs('PostsController.add');
$I->seeCurrentActionIs('posts@add');
$I->seeCurrentActionIs('posts.add');

Session

Insert key/value(s) in session with haveInSession($key, $value = null)

$I->haveInSession('redirect', Router::url(['_name' => 'dashboard']));
$I->haveInSession(['redirect' => Router::url(['_name' => 'dashboard'])]);

Assert key(/value) in session with seeInSession($key, $value = null)

$I->seeInSession('redirect'); // only checks the key exists.
$I->seeInSession('redirect', Router::url(['_name' => 'dashboard']));
$I->seeInSession(['redirect', Router::url(['_name' => 'dashboard'])]);

Assert key(/value) not in session with dontSeeInSession($key, $value = null)

$I->dontSeeInSession('redirect'); // only checks the key does not exist.
$I->dontSeeInSession('redirect', Router::url(['_name' => 'dashboard']));
$I->dontSeeInSession(['redirect', Router::url(['_name' => 'dashboard'])]);
