JUnit Parameterized tests not running in isolation with Mockito, Spring, Reflection and AspectJ
<p>I have the below test class, which has been stripped to the bare minimum needed to reproduce the issue:</p>

<pre><code>@RunWith(Parameterized.class)
@ContextConfiguration(locations = { "classpath:restful-service-test-context.xml" })
@DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD)
public class ResftulServiceTest {

    @Autowired
    @Qualifier("failedAspectTestMessage")
    private String failedAspectTestMessage;

    @Autowired
    private ProviderService ProviderService;

    private String methodName;
    private Set valuesToReturnByMock;
    private TestContextManager testContextManager;

    public ResftulServiceTest(String methodName, String[] valuesToReturnByMockArray) {
        this.methodName = methodName;
        this.valuesToReturnByMock = new HashSet&lt;&gt;(Arrays.asList(valuesToReturnByMockArray));
    }

    @Parameterized.Parameters
    public static Collection values() {
        return Arrays.asList(new Object[][] { { "getCountries", new String[] { "GB", "US" } }, });
    }

    @Before
    public void setUpSpringContext() throws Exception {
        testContextManager = new TestContextManager(getClass());
        testContextManager.prepareTestInstance(this);
    }

    @Test
    public void testGetValues_Fail_MyException() throws Exception {
        Method methodInProviderService = ProviderService.class.getDeclaredMethod(methodName);

        Mockito.when(methodInProviderService.invoke(ProviderService))
                .thenThrow(new MyException(failedAspectTestMessage, StatusCodeType.ERROR));
    }

    @Test
    public void testGetValues_Fail_Exception() throws Exception {
        Method methodInProviderService = ProviderService.class.getDeclaredMethod(methodName);

        Mockito.when(methodInProviderService.invoke(ProviderService))
                .thenThrow(new AspectException(failedAspectTestMessage));
    }
}
</code></pre>

<p>If I run each of the tests separately, they work fine. However, if I run all of them, <code>testGetValues_Fail_Exception</code> fails on the Mockito line with error:</p>

<p>If I replace the <code>.thenThrow</code> in <code>testGetValues_Fail_MyException</code> with <code>.thenReturn</code>, it all works fine, so at some point the isolation is being broken. <strong>How can I fix this problem?</strong></p>
