org.powermock.reflect.exceptions.FieldNotFoundException

Question

Good day I've got class with 2 methods: first is public GetLeadRequestsList - I want to test it, and second is private LeadRequestListResponse - used by first method. I mocked second method and called first one. Code of my test is here. When I run testGetLeadRequestsList, I catched
org.powermock.reflect.exceptions.FieldNotFoundException: No static field of type "org.mockito.internal.progress.MockingProgress" could be found in the class hierarchy of org.mockito.Mockito.

error in testclass is in the String: doReturn(leadRequestsResponse).when(mock, "LeadRequestListResponse", ArgumentMatchers.anyBoolean());

        } catch (Exception e) {
            System.out.println(e.getMessage());
        }

}

Maybe, anybody know how to check with Error. Thank's in advance

Answer 1

I suppose you use not correct versions of mockito-core and powermock-api-mockito. Because FieldNotFoundException could be if using not compatible versions of these libraries. Please use support versions chart - https://github.com/powermock/powermock/wiki/Mockito#supported-versions

So you need check your versions and correct it.

Also you should do next things:

1. Add @RunWith(PowerMockRunner.class) and @PrepareForTest(LeadRequestsControllerImpl.class) before LeadRequestsControllerImplTest
2. Change from TestNG @BeforeMethod to JUnit annotations (for example @BeforeClass) because you can't mixed it.
