Singleton班级没有被嘲笑

Question

我有一个Singleton类Svnplugin的getInstance（）我需要模拟以返回模拟对象。但这并没有被嘲笑。我正在使用PowerMock和Easymock。

以下是我的测试代码

@Test
@PrepareForTest({SVNPlugin.class})
public void createGlobalUSerTest() throws Exception{
    PowerMock.mockStatic(SVNPlugin.class);
    SVNPlugin svnPlugin=PowerMock.createMock(SVNPlugin.class);
    PowerMock.expectNew(SVNPlugin.class).andReturn(svnPlugin);      
    EasyMock.expect(SVNPlugin.getInstance()).andReturn(svnPlugin).anyTimes();
    EasyMock.expect(svnPlugin.getSynProject("", "", "", "")).andReturn(true);
    PowerMock.replay(SVNPlugin.class,svnPlugin);
    Future<RpcResult<CreateGlobalUserOutput>> 
       result=impl.createGlobalUser(getGLobalUser());
    PowerMock.verify(svnPlugin,SVNPlugin.class);
    Assert.assertNotNull(result);       
}

需要模拟的示例代码

SVNPlugin svnplugin = SVNPlugin.getInstance();
checkOutFlg = svnplugin.getSynProject(checkOutLocationAtLocal, svnPath , userName, passWord);

我无法理解我做错了什么。

快速答案是您需要PowerMock Runner。

那么，实际上您不需要模拟new，因为模拟getInstance就足够了。

我以为SVNPlugin是最终的，它证明使用PowerMock创建的模拟合理。所以我尝试了此实现。

public final class SVNPlugin {
  public static SVNPlugin getInstance() {
    return new SVNPlugin();
  }
  private SVNPlugin() {}
  public boolean getSynProject(String s, String s1, String s2, String s3) {
    return false;
  }
}

，以下测试正常工作。

@RunWith(PowerMockRunner.class)
public class SVNPluginTest {
  @Test
  @PrepareForTest(SVNPlugin.class)
  public void createGlobalUSerTest() throws Exception{
    PowerMock.mockStatic(SVNPlugin.class);
    SVNPlugin svnPlugin = PowerMock.createMock(SVNPlugin.class);
    EasyMock.expect(SVNPlugin.getInstance()).andStubReturn(svnPlugin);
    EasyMock.expect(svnPlugin.getSynProject("", "", "", "")).andReturn(true);
    PowerMock.replay(SVNPlugin.class,svnPlugin);
    SVNPlugin svnplugin = SVNPlugin.getInstance();
    boolean checkOutFlg = svnplugin.getSynProject("", "", "", "");
    assertTrue(checkOutFlg);
    PowerMock.verify(svnPlugin,SVNPlugin.class);
  }
}
