Testing of spring boot process application

    Details

      Description

      Currently if we create integration test for SpringBootProcessApplication it is "conflicting" with other integration tests using TestApplication in SpringBootTest.
      The error that we see is similar to this:

      The problem must be in the fact, that tests are reusing application context.

          These two conditions must be satisfied, in order to process application integration tests work fine:
          1. When some classes are listed inside @SpringBootTest annotation, they must live in separate package, as they will be used as a base for loading Spring application context, which must be as small and focused as possible.
          2. All integration tests for process applications must declare:

          @DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_CLASS)
