LocationPickerActivity is showing MapboxConfigurationException while creating it in a test class

Description

I was trying to add tests for the LocationPickerActivity class. But getting errors while building the class. Can’t find any solution for that.

What I was doing

Error

Caused by: com.mapbox.mapboxsdk.exceptions.MapboxConfigurationException: 
Using MapView requires calling Mapbox.getInstance(Context context, String accessToken) before inflating or creating the view. The access token parameter is required when using a Mapbox service.
Please see https://www.mapbox.com/help/create-api-access-token/ to learn how to create one.

I think the exception is occurring because of using Mapview and it’s asking for this Mapbox.getInstance(Context context, String accessToken). But NearbyParentFragment also is using mapview in the same way, it’s not giving error while inflating the layout in the test.

@madhurgupta10 That’s great. Sure I will add instrumentation tests too. However, I created unit tests for the class covering as much as possible.

Thanks a lot for the help.

@madhurgupta10 I think without calling .create() onCreate will not be covered. Isn’t it?

Yes, for now, you can skip onCreate and write tests for other methods
