Subject Re: Unable to do unit testing Awscredentialprovidercontrolerservice
Date Thu, 17 Oct 2019 16:02:14 GMT
Please only email one list, removing users...

The AWS processors depend on an interface called
AWSCredentialsProviderService.  The unit test of the processor should
not need to depend on real implementations of this interface,
otherwise it is really an integration test of multiple components.

I would suggest testing your processor and service separately... the
processor test can mock the AWSCredentialsProviderService interface.

this custom Awscredentialprovidercontrolerservice is working or not like if I get invalid
bucket name then test case should failed.

creation line as custom controller service project is not available to this processor service
project. If we add dependency in pom file to make it available then it will be circular dependency.
