Installing and using Codeception in Yii 2

Yii comes with its own Codeception extension that provides a base class for unit tests (yiicodeceptionTestCase), a class for tests that require database interaction (yiicodeceptionDbTestCase), and a base class for Codeception page objects (yiicodeceptionBasePage).

As usual, our preferred method is using Composer:

$ composer require "codeception/codeception: 2.0.*" --prefer-dist --dev

There’s a specific reason to use –prefer-dist; if you’re using Git, you can get into a hairy situation with Git submodules (but again excluding the /vendor folder should solve most of these problems). To avoid repeating it every time we use Composer, just add the following to your composer.json file:

// composer.json

{
    "config": {
        "preferred-install": "dist"
    }
}

Also, remember that using composer install will not work if you’ve added the component manually to your composer.json file as it would consider it a mismatch and raise an error. To install the package, you need to run composer update either for all the packages you have installed, or specifically with this:

$ composer update codeception/codeception

As highlighted before, you might also be interested in two additional packages codeception/specify and codeception/verify. These two packages provide a further level of abstraction that allows you to write more human readable tests by using a business-oriented syntax, close to what BDD definitions will look like.

Your composer.json file will contain the following:

// composer.json

{
    "require-dev": {
        "yiisoft/yii2-codeception": "*",
        "yiisoft/yii2-debug": "*",
        "yiisoft/yii2-gii": "*",
        "codeception/codeception": "2.0.*",
        "codeception/specify": "*",
        "codeception/verify": "*"
    }
}
