Gradle configuration detection and Spring Repository Beans mocked

Release date: Apr 14, 2020

Gradle configuration is now automatically detected, and Spring Repository Beans are mocked using @MockBean and Mockito. Tests are now created that require calling setter methods and require more complex constructors, increasing the number of branches tested.
