如何在playframework中爲功能測試設置數據庫/燈具

Question

我想測試我的Controller - Secure.java。我使用play的Fixtures類來設置數據庫。不幸的是，當POST調用發出並且控件的方法被調用時，數據庫變成空的。但是，在測試方法中，我可以按預期檢索數據。

的路由

POST /login          user.Secure.authenticate 

控制器Secure.java：

你的功能測試運行中，將在測試結束時結束事務。因此，在測試完成之前，您在此事務中執行的所有操作都不會提交給數據庫。因此，在這種情況下，您可以使用作業創建僅用於設置的新交易

@Before 
public void setUp() throws Exception { 
    new Job() { 
     @Override 
     public void doJob() throws Exception { 
      Fixtures.deleteDatabase(); 
      Fixtures.loadModels("testusers.yaml"); 
      Cache.clear(); 
     } 
    }.now().get(); 
}
