Subject Re: Unit test is getting failed for custom ,Awscredentialprovidercontrolerservice

You shouldn't be modifying the service code to make the test pass.

You need to set whatever properties are needed to make it valid by
using Runner.setProperty(service, property name, value)

unit test is working fine.But problem is these parameters are appearing in the NiFi UI of
