Functional Tests
 | 
						|
================
 | 
						|
 | 
						|
Functional test verifies scenarios from a user's perspective. It is similar to [acceptance test](test-acceptance.md)
 | 
						|
but instead of communicating via HTTP it is filling up environment such as POST and GET parameters and then executes
 | 
						|
application instance right from the code.
 | 
						|
 | 
						|
Functional tests are generally faster than acceptance tests and are providing detailed stack traces on failures.
 | 
						|
As a rule of thumb, they should be preferred unless you have a special web server setup or complex UI powered by
 | 
						|
JavaScript.
 | 
						|
 | 
						|
Functional testing is implemented with the help of Codeception framework which has a nice documentation about it:
 | 
						|
 | 
						|
- [Codeception for Yii framework](https://codeception.com/for/yii)
 | 
						|
- [Codeception Functional Tests](https://codeception.com/docs/04-FunctionalTests)
 |

## Running basic and advanced template tests
 | 
						|
 | 
						|
If you've started with advanced template, please refer to ["testing" guide](https://github.com/yiisoft/yii2-app-advanced/blob/master/docs/guide/start-testing.md)
 | 
						|
for more details about running tests.  
 | 
						|
 | 
						|
If you've started with basic template, check its [README "testing" section](https://github.com/yiisoft/yii2-app-basic/blob/master/README.md#testing).
