如何清除/刪除數據庫含量研究（功能）測試中playframework

發揮框架：1.2.3如何清除/刪除數據庫含量研究（功能）測試中playframework

嗨，

我試圖通過劇中的夾具來清除我的數據庫。但是，我遇到了一些問題。

首先，Fixtures.deleteDatabase（）刪除整個數據庫和玩不重新創建它在另一個測試（也我還沒有發現任何這樣做的。

其次，試圖deleteAllModules（）我得到一個。例外的任何樣板戲試圖刪除：

java.sql.SQLException: Lock wait timeout exceeded; try restarting

這些模型使用正常Model.save（）在測試過程中已經創建我假設 - 再一次 - 交易進入我的路不知何故不過，。看着數據庫，所有的型號都會持續存在。

@After 
public void tearDown() throws InterruptedException, ExecutionException { 
    new Job() { 
     @Override 
     public void doJob() throws Exception { 
      Logger.debug("[SetupUtils.createClearDBJob().new Job() {...}] Deleting database"); 
      Fixtures.deleteAllModels(); 
      //    Fixtures.delete() 
      //    Fixtures.deleteDatabase(); 
     } 
    }.now().get(); 
}

全堆棧跟蹤

究竟是什麼問題，你必須先刪除數據庫，刪除數據庫中的所有內容，並在例如使用Fixtures.loadModels創建數據之後：你還需要什麼？ – 2012-03-15 16:12:06

Fixtures.deleteDatabase（）刪除整個數據庫，play在下一次測試中不會重新創建它，因此加載模型也失敗。所以我不能那樣做。我正在尋找一種方法來刪除所有表中的所有行，但沒有別的。另一種方法是刪除所有表，甚至刪除整個數據庫，然後讓它重新創建。然而，沒有找到辦法做到這一點 – forste 2012-03-19 13:35:54

你可以嘗試設置創建/自舉刪除operaton，並檢查播放！正在測試模式或生產模式下運行。

@OnApplicationStart 
public class Bootstrap extends Job { 

    public void doJob() { 
    if (Play.mode == Play.Mode.DEV) { 
     DropboxFolder.deleteAll(); // delete 
     Fixtures.load("samples_data.yml"); // recreate 
    } 
    } 
}
