### Question:
RepositoryJpaLayerProvider extends CoreLayerProvider { public MemberTypeAdditions getMemberTypeAdditions(final String callerMID, final String methodIdentifier, final JavaType targetEntity, final JavaType idType, final MethodParameter... callerParameters) { return getMemberTypeAdditions(callerMID, methodIdentifier, targetEntity, idType, true, callerParameters); }  int getLayerPosition(); MemberTypeAdditions getMemberTypeAdditions(final String callerMID,
      final String methodIdentifier, final JavaType targetEntity, final JavaType idType,
      final MethodParameter... callerParameters); MemberTypeAdditions getMemberTypeAdditions(final String callerMID,
      final String methodIdentifier, final JavaType targetEntity, final JavaType idType,
      boolean autowire, final MethodParameter... callerParameters);  }### Answer:
@Test public void testGetAdditionsForNonRepositoryLayerMethod() { final MemberTypeAdditions additions = layerProvider.getMemberTypeAdditions(CALLER_MID, "bogus", mockTargetEntity, mockIdType); assertNull(additions); }
@Test public void testGetAdditionsWhenNoRepositoriesExist() { final MemberTypeAdditions additions = layerProvider.getMemberTypeAdditions(CALLER_MID, FIND_ALL_METHOD.name(), mockTargetEntity, mockIdType); assertNull(additions); }
