在TestCase中启动第二个活动(这不是被测活动)

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

我的问题是:

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

...导致错误“意图正在进行...解析为不同的进程...测试”。 对Intent使用getTargetContext()导致“无法解析Intent的活动”,因为我的mock类不是app包的一部分。

测试应用程序不是传统意义上的“应用程序”,无法启动自己的活动。如果您需要测试活动如何响应发送其意图的其他活动,则可以在实际调用getActivity()之前使用ActivityInstrumentationTestCase2.setActivityIntent(Intent)方法注入要测试的各种意图。

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
    }
}
