Robolectric + Emma：初始化錯誤

Question

我已經爲使用Junit，Mockito，PowerMock和Robolectric的Android編寫了單元測試，並使用Robolectric測試運行器通過命令行在Linux環境中運行這些測試。 我想使用Emma命令行生成覆蓋率報告。

我正面臨着下面的錯誤。

FAILURES!!! 
Tests run: 1, Failures: 1 

請有人幫我解決這個問題。謝謝

Robolectric附帶的初始化錯誤可以通過您的測試類中的註釋org.robolectric.annotation.internal.DoNotInstrument來解決。像：

@RunWith(RobolectricTestRunner.class) 
@Config(constants = BuildConfig.class) 
@DoNotInstrument 

public class MyActivityTest { 
    .. 
}
