Testing environment setup
|
|
======================
|
|
|
|
> Note: This section is under development.

Yii 2 has officially maintained integration with [`Codeception`](https://github.com/Codeception/Codeception) testing
|
|
framework that allows you to create the following test types:
|
|
|
|
- [Unit testing](test-unit.md) - verifies that a single unit of code is working as expected;
|
|
- [Functional testing](test-functional.md) - verifies scenarios from a user's perspective via browser emulation;
|
|
- [Acceptance testing](test-acceptance.md) - verifies scenarios from a user's perspective in a browser.
|
|
|
|
Yii provides ready to use test sets for all three test types in both
|
|
[`yii2-basic`](https://github.com/yiisoft/yii2-app-basic) and
|
|
[`yii2-advanced`](https://github.com/yiisoft/yii2-app-advanced) project templates.
|
|
|
|
In order to run tests you need to install [Codeception](https://github.com/Codeception/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 `global` directive:
|
|
|
|
```
|
|
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>
|
|
```
|
|
|
|
Then add `<directory>/vendor/bin` to you `PATH` environment variable. Now we're able to use `codecept` from command
|
|
line globally.
|
|
|
|
> Note: global installation allows you use Codeception for all projects you are working on your development machine and
|
|
allows running `codecept` shell 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.
