如何在 ActivityInstrumentationTestCase2 或 InstrumentationTestCase 中启动第二个（模拟）活动？

我的问题是这样的：

Intent intent = new Intent(getInstrumentation().getContext(), MyMock.class);
myMock = (MyMock) getInstrumentation().startActivitySync(intent);

...导致错误“intent in process ... resolves to different process ...test”。对 Intent 使用 getTargetContext() 会导致“无法解析 Intent 的活动”，因为我的模拟类不是应用程序包的一部分。

测试应用程序不是传统意义上的“应用程序”，不能启动自己的活动。如果您需要测试您的活动如何响应发送它的意图的其他活动，您可以在实际调用 getActivity() 之前使用 ActivityInstrumentationTestCase2.setActivityIntent(Intent) 方法注入您想要测试的各种意图。

public class ExampleTest extends ActivityInstrumentationTestCase2 {

    // if your test runs on the UI thread, you will need to setActivityIntent() 
    // in setUp() as you won't have a chance to do it before the activity
    // is started

    // @UiThreadTest
    public void testMockIntent() {
        setActivityIntent(new Intent());
        Activity foo = getActivity();

        assertNotNull(foo); // your tests
    }
}
