Hello

Brief info about class under Test.
The class will fetch secret, certificate and access token from KeyVault and login.mirosoftonline.com. Also using Corbertura as code coverage tool.
I am trying to write testcases (using Junit, Mockito) for the below classes, but unable to find correct way.

SecretClient
SecretClientBuilder
KeyVaultSecret
ConfidentialClientApplication
ClientCredentialParameters

Some problems I found is as the above classes are marked as final, so unable to Mock. Also if I try to use PowerMock, Corbertura doesnt detect the code covered by it.

Please suggest any alternative way of testing so that my code coverage also gets calculated using corbertura.

Thanks!

    Hello, you should not need to mock implementations but interfaces, such as IConfidentialClientApplication (implemented by ConfidentialClientApplication). To make your classes (unit) testable you should inject interfaces as dependencies.
