机器人Emma:初始化错误

Question

我使用JUnit、Mockito、PowerMock和Robolectic编写了android的Unit测试，并使用Robolectic Test Runner通过命令行在Linux环境中运行这些测试。我想使用Emma命令行生成覆盖报告。

我面临以下错误。

请有人帮我做这个。谢谢

Answer 1

Robolectric 附带的初始化错误可以通过测试类上的注释组织.robolectric.annotation.internal.DoNotinsment 来解决。喜欢：

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

public class MyActivityTest {
  ..
}
