Testing environment setup
Note: This section is under development.
Yii2 has officially maintained integration with
framework that allows you to create the following test types:
- Unit testing - verifies that a single unit of code is working as expected;
- Functional testing - verifies scenarios from a user's perspective via browser emulation;
- Acceptance testing - verifies scenarios from a user's perspective in a browser.
In order to run tests you need to install Codeception. You can install it either locally - for particular project only, or globally - for your development machine.
For the local installation use following commands:
composer require "codeception/codeception=2.0.*" composer require "codeception/specify=*" composer require "codeception/verify=*"
For the global installation you will need to use
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 before, run
composer global status. It should output:
Changed current directory to <directory>
<directory>/vendor/bin to you
PATH environment variable. Now we're able to use
codecept from command
Note: global installation allows you use Codeception for all projects you are working on your development machine and allows running
codeceptshell command globally without specifying path. However, such approach may be inappropriate, for example, if 2 different projects require different versions of Codeception installed. For the simplicity all shell commands related to the tests running around this guide are written assuming Codeception has been installed globally.
