Test Image Picking - Testing on Android - Part 14 

One of the coolest tutorials thanks from india sir🙏

If anyone runs into issue with building creating viewModel using ViewModelFactory, I had to replace it with "val viewModel by viewModels()" initialization instead. You also need to annotate fragments and MainActivity with "@AndroidEntryPoint" if initializing viewModel this way

🙌🙌🙌

Hi Philip, Thanks for this awesome series, just one question. 25:19 You used "assert" after "verify" so if that test fails how would we know the exact reason whether verify failed or assert? Shouldn't we break it into two independent tests to avoid ambiguity?

Phillip, looks like in newer versions of hilt it is not possible to access viewmodel or imageAdapter inside launchFragmentInHiltContainer block. Could you please check on that?

I've run into a problem. Navigation crashes because ImagePickFragment doesn't have an empty constructor - it uses @Inject constructor with adapter. But then FragmentFactory also has an @Inject constructor with the adapter... I'm confused by this. The AppModule doesn't even provide the adapter, so why is there even an @Inject? Is Hilt able to construct these without specifying it, so long as it has the things necessary?

Thank you so much for this video :)

Hi Phillip, nice tutorial, this is an adapter question. Do you know why when using RoomDatabase and LiveData, AsyncListDiffer emits a different list if a particular element is removed or added to the list. So, for example if you have a list of 1,2,3 and you add 4 to the list. LiveData and Room know there is 1,2,3,4 in your list but AsyncListDiffer.currentList will return 1,2,3. But if you change the list, or delete item 2 from Room, Room and LiveData will return 1,3,4 but AsyncListDiffer.currentList will return 1,2,3,4 even if I call submitList() function anytime I change my list.

"Run Android instrumented tests using Gradle" option was ignored because this module type is not supported yet. when i run test , get this error . can you help me ?!

Very useful information))

24:42 what if the view model of ImagePickFragment need to be val and assigned by ActivityViewModels?

is there a way to use a viewmodel with the test repository when initializing the viewmodel with viewModels and activityViewModels property delegates ??

Non-Mockito version: imageUrl + testViewModel; launchFragmentInHiltContainer(fragmentFactory = fragmentFactory) { setGraph + setViewNavController + navigate; imageAdapter.images...; viewModel = testViewMode }; navController.popBackStack(); assertThat()___Use this example to get answer for blank test of video 13: imageUrl + testViewModel; testVM.setCurImageUrl(imageUrl); launchFragmentInHiltContainer {setGraph + setViewNavController + navigate; viewModel = testViewModel }; pressBack(); runOnUiThread {assertThat}

You created the fragment factory but you didn't use it. Where did you set it to a fragment manager and i also didn't find this in the source code

very cool

It was a long but very useful video (20%s in 80/20 principle) 👍 I learned a lot of things. just please consider using ListAdapter instead of normal recyclerview adapter in your videos. thanks.

Can you link the documentation for Fragment and Navigation testing you used for these videos?

Great videos man, will you make a dagger hilt series man?

Hey .. How can i upload a pdf file to firebase store with the same name it has via an intent?

if i have several adapters what add to constructor in FragmentFactory class?

you are fucking awesome

👍👊👌

Hi, Will you do a workout fitness app tutorial on Kotlin?
