Android单元测试与AppCompat项目库

Question

我有一个项目，有一些单元测试扩展了ActivityUnitTestCase，但是当我安装android-support-v7-appcomapt项目库来使用ActionBar时，这些测试已经停止工作了。我还有一些ActivityInstrumentationTestCase2测试，它们工作得很好。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, veActivity是空的。

我尝试了在StackOverflow中找到的许多建议，其中大多数都导致了这个例外。

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

Answer 1

使用launchActivity创建了一个解决方案，并确保已启动的活动已经完成。手动设置主题，启动等待空闲同步的活动，并在测试后完成该活动。

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

必须使用:

setActivityIntent(intent);

你不需要指定何时开始你的活动，它会自动完成
