Yii 2 Advanced Application Template is a skeleton Yii 2 application best for developing complex Web applications with multiple tiers.

The template includes three tiers: front end, back end, and console, each of which is a separate Yii application.

The template is designed to work in a team development environment. It supports deploying the application in different environments.

	controllers/		contains console controllers (commands)
	migrations/			contains database migrations
	models/				contains console-specific model classes
	runtime/			contains files generated during runtime
	tests/				contains various tests for the console application

The minimum requirement by this application template that your Web server supports PHP 5.4.0.

Extract the archive file downloaded from yiiframework.com to a directory named advanced that is directly under the Web root.

Then follow the instructions given in "GETTING STARTED".

If you do not have Composer, you may install it by following the instructions at getcomposer.org.

You can then install the application using the following command:

php composer.phar create-project --prefer-dist --stability=dev yiisoft/yii2-app-advanced advanced

After you install the application, you have to conduct the following steps to initialize the installed application. You only need to do these once for all.

1. Run command init to initialize the application with a specific environment.
2. Create a new database and adjust the components['db'] configuration in common/config/main-local.php accordingly.
3. Apply migrations with console command yii migrate. This will create tables needed for the application to work.
4. Set document roots of your Web server:

• for frontend /path/to/yii-application/frontend/web/ and using the URL http://frontend/
• for backend /path/to/yii-application/backend/web/ and using the URL http://backend/

To login into the application, you need to first sign up, with any of your email address, username and password. Then, you can login into the application with same email address and password at any time.

Install additional composer packages:

• php composer.phar require --dev "codeception/codeception: 1.8.*@dev" "codeception/specify: *" "codeception/verify: *"

This application boilerplate use database in testing, so you should create three databases that are used in tests:

• yii2_advanced_unit - database for unit tests;
• yii2_advanced_functional - database for functional tests;
• yii2_advanced_acceptance - database for acceptance tests.

To make your database up to date, you can run in needed test folder yii migrate, for example if you are starting from frontend tests then you should run yii migrate in each suite folder acceptance, functional, unit it will upgrade your database to the last state according migrations.

To be able to run acceptance tests you need a running webserver. For this you can use the php builtin server and run it in the directory where your main project folder is located. For example if your application is located in /www/advanced all you need to is: cd /www and then php -S 127.0.0.1:8080 because the default configuration of acceptance tests expects the url of the application to be /advanced/. If you already have a server configured or your application is not located in a folder called advanced, you may need to adjust the TEST_ENTRY_URL in frontend/tests/_bootstrap.php and backend/tests/_bootstrap.php.

After that is done you should be able to run your tests, for example to run frontend tests do:

• cd frontend
• ../vendor/bin/codecept build
• ../vendor/bin/codecept run

In similar way you can run tests for other application tiers - backend, console, common.
