/**

@RunWith(AndroidJUnit4.class)

public void useAppContext() {

你甚至可以使用 runOnMainSync在主线程上运行它。下面是完整的解决方案:
@RunWith(AndroidJUnit4::class)
class AwesomeViewModelTest {
@Test
fun testHandler() {
getInstrumentation().runOnMainSync(Runnable {
val context = InstrumentationRegistry.getInstrumentation().targetContext
// Here you can call methods which have Handler
})
}
}
