Why does ExceptionInInitializerError occur when invoking HtmlCompat in an Android unit test using Robolectric?

Asked 2022-Mar-21 at 13:56

I am attempting to unit test a method that is part of my use case layer of an Android app. The method receives an XML RSS feed and returns it to the view model as GSON-parsed objects. The testing class is annotated with @RunWith(RobolectricTestRunner::class).

The test fails because a java.lang.ExceptionInInitializerError (among others) is thrown by .fromHtml() within this method of the use case class:

App is not able to find DynamicFeature navigation graph. Getting Resources$NotFoundException for the navigation graph

Asked 2022-Feb-16 at 06:49

I am using Android's Dynamic delivery for one of my feature. I have separated the code for the feature. I am also using the Navigation component in my project.

I can see dynamicfeature being downloaded from the progress bar and after downloading I am using Navigation component to navigate to Fragment2.

However, when I am trying to navigate from Fragment1 which is in my "app" to Fragment2 which is in my "dynamicfeature" I am getting below exception.

...

ANSWER

Answered 2022-Feb-16 at 06:49

I was able to resolve this issue. Apparently, if you use tag for navigating into the dynamic feature module. You have to specify ProgressFragment which extends AbstractProgressFragment and specify it as app:progressDestination.

Also since Fragment1 is in base app, which is hosted by activity in base app. We need to override attachBaseContext method in this activity too like below. This will fix the case where same exception was occurring at the subsequent launch.

You can use reflections to access the private field private var rowClick: RowEventCallback? = null of the custom view and then you can call the click interface in the test.

So the test should look something like this

Error inflating ViewBinding in test class : Binary XML file line #38: Binary XML file line #38: Error inflating class

Asked 2021-Dec-17 at 09:54

I am trying to write unit tests for a RecyclerView.ViewHolder class which uses ViewBinding but I am facing issues to inflate my ViewBinding in my test class, having this error when running my test : Binary XML file line #38: Binary XML file line #38: Error inflating class Caused by: java.lang.UnsupportedOperationException: Failed to resolve attribute at index 5: TypedValue{t=0x2/d=0x7f04015d a=2}

I could not find code examples of ViewBinding inflate in test classes, is that possible ? I found this StackOverflow thread but it uses PowerMock to mock a ViewBinding class. I'm using mockK in my project and I think using a real ViewBinding instance would be better in my case.

My ViewHolder looks like this :

ANSWER

Answered 2021-Dec-15 at 13:55

I was able to get this working (using Mockito, but it should be applicable to MockK too) by looking in the generated binding class to see what methods I needed to mock to get it to inflate and return mocked views properly. These files are in app/build/generated/data_binding_base_class_source_out/debug/out/your/package/databinding for a standard build

Here is an example of a generated data binding class with three views in a ConstraintLayout.

Install robolectric

Robolectric supports running tests against multiple Android API levels. The work it must do to support each API level is slightly different, so its shadows are built separately for each. To build shadows for every API version, run:.
If you would like to live on the bleeding edge, you can try running against a snapshot build. Keep in mind that snapshots represent the most recent changes on master and may contain bugs.

Support

Robolectric is built using Gradle. Both IntelliJ and Android Studio can import the top-level build.gradle file and will automatically generate their project files from it.
