在Espresso测试中模拟Intent Extras

我正试图Activity在浓缩咖啡中推出.问题是我想把嘲笑的额外内容放到Intent我用来启动它的地方Activity.这是一个例子.

@RunWith(AndroidJUnit4.class)
public final class NiceActivityTester
{
    @Rule
    public final ActivityTestRule activityRule = new ActivityTestRule<>(NiceActivity.class, true, false);

    @Test
    public void justStartPlease() {
        NiceThing niceThing = Mockito.mock(NiceThing.class);
        Mockito.when(niceThing.getName()).thenReturn("Nice!");

        Intent intent = new Intent(InstrumentationRegistry.getTargetContext(), NiceActivity.class);
        intent.putExtra("NICE_THING", niceThing);

        activityRule.launchActivity(intent);
    }
}

不幸的是,解组Parcelable失败了.

有没有办法使用模拟的附加功能Intent？也许关于这个领域的一些最佳实践？

我真的不想为我正在使用的每个模型制作构造函数,其中一些类与十几个字段相当复杂.间谍额外或Intent使用Mockito没有帮助.

使用ActivityTestRule和覆盖getActivityIntent

在此处找到的示例

public class MainActivityLaunchIntentTest {

    @Rule
    public ActivityTestRule mActivityRule =
            new ActivityTestRule(MainActivity.class) {
                @Override
                protected Intent getActivityIntent() {
                    Context targetContext = InstrumentationRegistry.getInstrumentation().getTargetContext();
                    Intent result = new Intent(targetContext, MainActivity.class);
                    result.putExtra("Name", "Earth");
                    return result;
                }
            };

    @Test
    public void shouldShowHelloEarth() {
        onView(withId(R.id.main__tv_hello)).check(matches(withText("Hello Earth!")));
    }
}
