嘲笑創建ThreadSafeClientConnManager對象的類

Question

我無法模擬一個類（使用PowerMock的createMock方法）。該類正在其構造函數中創建ThreadSafeClientConnManager類的對象。 我在我通過我的類名稱調用createMock方法的那一行得到異常。 以下是異常堆棧跟蹤。但是，如果我運行集成測試，它工作正常。可能是什麼問題 ？

Answer 1

您認爲這是系統類加載問題嗎？嘗試引用這個鏈接，它可能會給你一些指針。 http://code.google.com/p/powermock/wiki/MockSystem。

Answer 2

您確定該類正在其構造函數中創建ThreadSafeClientConnManager嗎？它可以在靜態初始化器中完成嗎？如果是這樣的話，你可能會圍繞在你的測試類的「類」的定義之前加入以下兩個註解，例如：

@RunWith(PowerMockRunner.class) 
@PrepareForTest(ClassUnderTest.class) 
public class YourTestClass { 

注意< clinit>父初始化，顯示部分類的靜態初始化過程。
