Question

我有一个项目包含一些扩展ActivityUnitTestCase的单元测试，但是当我安装android-support-v7-appcomapt项目库来使用ActionBar时，这些测试已停止工作。我也有一些ActivityInstrumentationTestCase2测试，他们工作正常。这是我的设置

protected void setUp() throws Exception {
    super.setUp();      

    Intent intent = new Intent(getInstrumentation().getTargetContext(), MyActivity.class);              

    startActivity(intent, null, null); // The exception happens here
    veActivity = getActivity();

    //getInstrumentation().callActivityOnStart(veActivity);
}

如果我不调用startActivity，则veActivity为空。

我尝试了很多在StackOverflow中找到的建议，其中大部分都引出了我的异常。

android.content.pm.PackageManager$NameNotFoundException: ComponentInfo{mypackage/mypackage.MyActivity}

Answer 1

使用launchActivity创建一个变通方法，并确保已启动的活动已完成。手动设置主题，启动等待空闲同步的活动，并在测试后完成活动。

Context context = getInstrumentation().getTargetContext();
context.setTheme(R.style.Theme_AppCompat);
mActivity = launchActivity(context.getPackageName(),
    MyActivity.class, null);
getInstrumentation().waitForIdleSync();

// YOUR TESTS
// assertNotNull("The activity cannot be null.", mActivity);

sendKeys(KeyEvent.KEYCODE_BACK);
mActivity.finish();

Answer 2

我认为你的错误是：

startActivity(intent, null, null); // The exception happens here

您必须使用：

setActivityIntent(intent);

您无需指定开始活动，也可以自动完成。
