我正在尝试设置类似于
GithubBrowserSample的UI测试,看起来示例项目只有Frag的模拟viewmodel而不是Activity的示例.
这是我的代码,我试图通过模拟viewmodel来测试Activity.但viewmodel未在Activity中的onCreate()之前设置.
@RunWith(AndroidJUnit4::class)
class MainActivityTest {
val viewmodel = mock(Mainviewmodel::class.java)
@Rule
@JvmField
val activityRule = ActivityTestRule<MainActivity>(MainActivity::class.java,true,true)
private val liveData = MutableLiveData<Resource<Object>>()
@Before
open fun setUp() {
activityRule.activity.viewmodelFactory = createviewmodelFor(viewmodel)
`when`(viewmodel.liveData).thenReturn(liveData)
viewmodel.liveData?.observeForever(mock(Observer::class.java) as Observer<Resource<Object>>)
liveData.postValue(Resource.success(Object()))
}
fun <T : viewmodel> createviewmodelFor(model: T): viewmodelProvider.Factory =
object : viewmodelProvider.Factory {
override fun <T : viewmodel> create(modelClass: Class<T>): T {
if (modelClass.isAssignableFrom(model.javaClass)) {
return model as T
}
throw IllegalArgumentException("unexpected model class " + modelClass)
}
}
}
有人可以帮我解决这个问题吗？
