Android Roboelectric 3.0测试下一个活动 - 从多个活动中选择

Question

我有这样的场景： -

我有三个活动ActivityA（启动器活动），ActivityB，ActivityC 现在，在Activity A中，我阅读了Application上下文，以决定是否启动ActivityB或ActivityC。

但即使在设置了上下文值手册之后，ActivityA也不会更新，第二个测试用例也会失败。有帮助吗？

    private ActivityA activityA;
    private ShadowActivity shadowActivity;
    @Before
    public void setUp() {
        activityA = Robolectric.setupActivity(ActivityA.class);
        assertNotNull("ActivityA not intsantiated", activityA);
        shadowActivity = Shadows.shadowOf(activityA);
    }

    @Test
    public void shouldStartActivityB() throws Exception
    {

        Intent intent = shadowActivity.peekNextStartedActivity();;
        assertEquals(ActivityB.class.getCanonicalName(), intent.getComponent().getClassName());
    }

      @Test
    public void shouldStartMainActivity() throws Exception
    {
ApplicationSettings.setWizardState(RuntimeEnvironment.application,  22);
        ShadowLog.d("Wizard state value", "" +ApplicationSettings.getWizardState(RuntimeEnvironment.application));// it prints 22
        activityA= Robolectric.setupActivity(ActivityA.class);
        shadowActivity = Shadows.shadowOf(activityA);
        Intent intent = shadowActivity.peekNextStartedActivity();
        ShadowLog.d("target activity is", intent.getComponent().getClassName());// This prints ActivityB instead of ActivityC
        assertEquals(ActivityC.class.getCanonicalName(), intent.getComponent().getClassName()); // this test case fails
    }
