@aurangzaibumer could we add a unit test for the ViewModel itself? You can mock anything you don't need/already tested in the Cache test if need be.

[ndegwamartin]

Lets add a verify assertion here to verify that the
defaultRepository.loadResource<Questionnaire>(questionnaireConfig.id) method was not called (i.e. was called zero times)

[ndegwamartin]

And we can probably split this to 2 unit tests to get better coverage for the changes in this class.

• Test case 1 to test for when the questionnaire is Found in the cache
• Test case 2 to test for when the questionnaire is Not Found in the cache

So basically use the:

val questionnaire =
      questionnaireViewModel.retrieveQuestionnaire(
        questionnaireConfig = questionnaireConfig,
      ) 

method as the focus of the test case and leave out the ContentCache.save invocations since those are already tested in the ContentCacheTest class

[ndegwamartin]

We can add some test cases for the Structure Map caching as well
