Our project is moving to SpringBoot 2 (using spring-starter-test) and Mockito 3.x .
In the integration tests, I converted the beans from @Mock to @MockBean annotation , removed @InjectMocks where it was not needed and also the MockitoAnnotations.initMocks(this) [either way not sure if it makes a difference]
When I run the test class individually (containing multiple test methods] , it runs successfully.
On running the whole test suite (3k tests), I start getting the error

}
Is it for some reason that the mocks are getting accessed ,before being created or something else altogether? Any help would be appreciated . Have been at it for a day or so now.
Update: Somehow the mocks are coming as one of the configuration classes that Spring is trying to load. For some reason, they are not getting cleared/reset . It does not happen in all combination of test cases.
