模擬靜態方法和AEM模擬

[英]Mocking Static Methods and AEM Mocks

 原文  2015-06-09 21:27:23  7   1    java/ maven/ unit-testing/ aem/ powermockito

問題描述

在安裝到AEM 5.6.1實例之前，我正在使用maven構建和測試我的代碼。 我已經編寫了使用wcm.io的實現從aem 模擬中受益的單元測試，以及需要使用powermockito模擬靜態方法的其他單元測試。

這是我對aem上下文，吊索模擬和powermock的依賴。

在我的課程中，我為aem上下文設置了規則，並准備了一些用於模擬的靜態類： 

@RunWith(PowerMockRunner.class)
@PrepareForTest({MyStatic.class})
public abstract class MyTest {

  @Rule
  public final AemContext context = new AemContext();

  @Mock
  protected MyStatic myStatic;
...

當我通過命令行運行mvn test時，收到以下異常： 

Tests run: 1, Failures: 0, Errors: 1, Skipped: 0, Time elapsed: 1.431 sec <<< FAILURE! - in com...MyTest
testTest(com.linkedin.aem.components.foundation.components.ParbaseTest)  Time elapsed: 0.183 sec  <<< ERROR!

如果我沒有為測試准備任何靜態類（刪除@PrepareForTest批注），則測試運行良好。 一旦添加注釋（即使是空的），就會出現問題。 我還有以下問題：

  1. 我的設置中有什么我可以更改的才能使其正常工作嗎？
  2. Aem上下文是否可以完全與靜態嘲笑一起使用？ （可能與另一個庫一起使用）
