java.lang.AbstractMethodError: org.powermock.api.mockito.internal.mockmaker.PowerMockMaker.isTypeMockable

Question

I am new to writing junit4 tests with spring boot I have explored all the SO questions to work around the following problem, I have done extensive research but I have not been able to get around this problem. I have been trying to run unit tests with SpringRunner using @MockBean and @AutoWired annotations, it is throwing following stack trace

    @Test
    public void triggerTest() {
        testSuiteRunner.trigger();
    }

}

Could some one list proper compatible dependency versions with spring boot2 and junit. PowerMock api is giving MockMaker issue while being used with spring2

Answer 1

The following github links helped in fixing the issue up, all I had to do was to upgrade the powermock-api version to 2.0.0-beta.5 to make it work properly with mockito2.
