unit-testing - Robolectric + 艾玛 : Initialization Error

Question

我使用 Junit、Mockito、PowerMock 和 Robolectric 编写了 Android 单元测试，并使用 Robolectric Test Runner 通过命令行在 Linux 环境中运行这些测试。 我想使用 Emma 命令行生成覆盖率报告。

我遇到以下错误。

请有人帮我解决这个问题。谢谢

Answer 1

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

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

public class MyActivityTest {
  ..
}
