 功能测试
 ================
 
-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.
+功能测试从用户的角度验证场景。它类似于[验收测试](test-acceptance.md)。
+但是它不是通过 HTTP 进行通信，而是填充环境，如（填充）POST 和 GET 参数，
+然后直接在代码里执行 Application 实例。
 
-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.
+功能测试通常比验收测试快，并且在失败时提供详细的堆栈跟踪。
+根据老司机的经验，功能测试应该是首选的，除非有专门的 Web 服务器设置
+或者由 JavaScript 构建的复杂 UI。
 
-Functional testing is implemented with the help of Codeception framework which has a nice documentation about it:
+功能测试是借助于具有良好文档的 Codeception 框架来实现的：

-## Running basic and advanced template tests
+## 运行基本模板和高级模板的测试
 
-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.  
+如果你使用的是高级模板，请参阅[测试指南](https://github.com/yiisoft/yii2-app-advanced/blob/master/docs/guide/start-testing.md)
+中关于运行测试的更多细节。  
 
-If you've started with basic template, check its [README "testing" section](https://github.com/yiisoft/yii2-app-basic/blob/master/README.md#testing).
