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
│           ├── AcceptanceHelper.php
│           ├── FunctionalHelper.php
│           └── UnitHelper.php
└── tests
    ├── Acceptance.suite.yml
    ├── Functional.suite.yml
    ├── Unit.suite.yml
    ├── Acceptance
    │   ├── .gitignore
    │   ├── bootstrap.php
    │   └── AcceptanceTester.php
    ├── Fixture
    │   └── dump.sql
    ├── Functional
    │   ├── .gitignore
    │   ├── bootstrap.php
    │   └── FunctionalTester.php
    └── Unit
        ├── .gitignore
        ├── bootstrap.php
        └── UnitTester.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)
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' => 'jadb@cakephp.org', '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' => 'jadb@cakephp.org']);
