同JUnit測試的螞蟻，但不是在Maven的

Question

我一個很奇怪的問題，想了解它的工作。

嗯，問題是當我嘗試運行Maven Test時，我的一些JUnit測試崩潰了，但是在Ant或Eclipse的插件中它完美地工作。

調試其中一個單元測試我發現了這個問題：當我將它運行到Maven中時，一個顯式設置爲「false」的模擬類中的布爾屬性總是「真」。這隻發生在一個用@Test註釋的方法中。

我猜其中一個方法正在改變我的屬性的值，就像類以不同的順序執行或類似的東西......我不知道。

我解決了它將變量再次變爲「false」到我的方法中，確保了我想要的值。

有人知道爲什麼會發生這種情況？

謝謝！

Maven的版本： 3.0.4

@After 
public void limpa() { 
    Mockit.restoreAllOriginalDefinitions(); 
} 

@Test 
public void testWithError() throws Exception { 
    Mockit.redefineMethods(MyObject.class, MyObjectMock.class); 
    MyOtherObject myOtherObject = createMyOtherObject(); 
    MyObjectMock.hasRules = false; 
    try { 
     myService.executeServiceA(myOtherObject); 
     Assert.fail("Can't get here. Should throw as exception."); 
    } catch (Exception e) { 
     Assert.assertEquals("Exception ", "You can't do this beacause of ...", e.getMessage()); 
    } 
} 

我的模擬：

public class MyObjectMock{ 

    //Others attibutes 
    (...) 
    public static boolean hasRules = false; 

    //Setters and getters 
    (...) 
}

Answer 1

不能在Ant和Maven算執行按相同的順序進行測試。如果測試有相互依賴關係，它也很容易陷入其中，單獨運行時測試通過的情況，但是當通過螞蟻/ Maven的運行，反之亦然失敗;或者只有在其他測試首先運行或類似時才通過。

要做的最好的事情是確保測試不相互依賴。如果測試因某種原因必須修改靜態數據，則應確保它在運行後重置靜態數據，以便每次測試都重新開始。例如：

public class NoRulesTest { 

    private static boolean oldRulesVal; 

    @BeforeClass 
    public static void NoRulesSetup() { 
     oldRulesVal = MyObjectMock.hasRules; 
     MyObjectMock.hasRules = false; 
    } 

    @AfterClass 
    public static void NoRulesTeardown() { 
     MyObjectMock.hasRules = oldRulesVal; 
    } 
}
