带有AppCompat项目库的Android单元测试

Question

I have a project with some unit tests that extends ActivityUnitTestCase, but when I installed the android-support-v7-appcomapt project library to use the ActionBar, these tests have stopped working. I also have some ActivityInstrumentationTestCase2 tests and they are working fine. This is my setup

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);
}

If I don't call startActivity, veActivity is null.

I tried many suggestions found here in StackOverflow and most of them lead me to this exception.

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

Answer 1

Created a workaround using launchActivity and making sure activities launched are finished. Set the theme manually, launch the activity waiting for idle Sync, and after your tests, finish the activity.

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();

I think your mistake is :

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

You must use :

setActivityIntent(intent);

You don't need to specify than you start your activity, it will be done automatically.
