Jira addon Unit Test fails with java.lang.NoClassDefFoundError: com/atlassian/jira/issue/IssueImpl

[Lukas Kotyza]

Hi, so I've been trying to learn more about unit tests for my jira addon but I hit wall pretty early. I have simple Unit test which mocks IssueManager with one issue. That looks fine but the problem is when I try to get the issue specifically with issuekey

@RunWith(MockitoJUnitRunner.class)
public class JiraServiceUnitTest {

    @Before
    public void setUp() throws Exception {
        MockIssueManager issueManager = new MockIssueManager();
        MockIssue issue = new MockIssue(10000, "FD-1001");
        issueManager.addIssue(issue);

        MockComponentWorker componentWorker = new MockComponentWorker();
        componentWorker.addMock(IssueManager.class, issueManager);
        componentWorker.init();
    }

    @Test
    // OK
    public void testIssueManager() {
        IssueManager issueManager = ComponentAccessor.getIssueManager();
        assertNotNull(issueManager);
    }

    @Test
    // OK
    public void testIssueSearchById() {
        IssueManager issueManager = ComponentAccessor.getIssueManager();
        Issue issue = issueManager.getIssueObject(10000L);
        assertNotNull(issue);
    }

    @Test
    // ERROR
    public void testIssueSearchByKey() {
        IssueManager issueManager = ComponentAccessor.getIssueManager();
        Issue issue = issueManager.getIssueObject("FD-1001");
        assertNotNull(issue);
    }
}

From research I did I learned that there might be a problem with jira java api loading for tests that has something to do with osgi and that it could be solved by adding

<bundle-instructions>
    <Import-Package>com.atlassian.jira.issue;resolution:="optional"</Import-Package>
</bundle-instructions>

to atlassian-plugin.xml. But this didn't work for me. The question is what am I doing wrong?
