java - 如何结合 PowerMock 和 Robolectric

Question

我有一个检查互联网状态的静态方法，它使用上下文。所以要模拟它，我需要使用 PowerMock。我正在使用 robolectric 来加快我的测试，因为我唯一需要模拟的就是模拟。但我似乎无法配置 PowerMock(1.6.6) 和 Robolectric(3.2.2) 一起工作。这就是我注释我的类(class)的方式:

@RunWith(RobolectricTestRunner.class)
@org.robolectric.annotation.Config(constants = BuildConfig.class, sdk = 21)
@PowerMockIgnore({"org.mockito.*", "org.robolectric.*", "android.*"})
@PrepareForTest({Utils.class})

设置方法中的这一行:

PowerMockito.mockStatic(Utils.class);

但是我收到这个异常:

org.powermock.api.mockito.ClassNotPreparedException: 
The class com.zeyad.usecases.data.utils.Utils not prepared for test.
To prepare this class, add class to the '@PrepareForTest' annotation.
In case if you don't use this annotation, add the annotation on class or  method level.
