This directory contains various tests for the advanced applications.

Tests in `codeception` directory are developed with [Codeception PHP Testing Framework](http://codeception.com/).

After creating and setting up the advanced application, follow these steps to prepare for the tests:

1. Install Codeception if it's not yet installed:

```
composer global require "codeception/codeception=2.0.*"
composer global require "codeception/specify=*"
composer global require "codeception/verify=*"
```

If you've never used Composer for global packages run `composer global status`. It should output:

```
Changed current directory to <directory>
```

Then add `<directory>/vendor/bin` to you `PATH` environment variable. Now we're able to use `codecept` from command
line globally.

2. Install faker extension by running the following from template root directory where `composer.json` is:

```
composer require --dev yiisoft/yii2-faker:*
```


3. Create three databases that are used in tests:

* `yii2_advanced_unit` - for unit tests;
* `yii2_advanced_functional` - for functional tests;
* `yii2_advanced_acceptance` - for acceptance tests.

Then update databases by applying migrations:

```
codeception/bin/yii_acceptance migrate
codeception/bin/yii_functional migrate
codeception/bin/yii_unit migrate
```

4. In order to be able to run acceptance tests you need to start a webserver. The simplest way is to use PHP built in
webserver. In the root directory where `common`, `frontend` etc. are execute the following:

```
php -S localhost:8080
```

5. Now you can run the tests with the following commands:

```
# frontend tests
cd frontend
codecept build
codecept run

# backend tests

cd backend
codecept build
codecept run

# etc.
```

If you already have run `codecept build` for each application, you can run all tests by a single `codecept run` in the
`tests` directory.
