Intellij IDEA Doesn't See Tests (java.lang.Exception: No tests found in class)

Question

Friends,

My IDEA refuses to see tests and barks out:

 java.lang.Exception: No tests found in class
at com.atlassian.plugins.osgi.test.AtlassianPluginsTestRunner.runViaRestCall(AtlassianPluginsTestRunner.java:125)
    at com.atlassian.plugins.osgi.test.AtlassianPluginsTestRunner.run(AtlassianPluginsTestRunner.java:75)

I have already tried the following:

• Rebuilding and restarting IDEA
• Cleaning the project
• Changing the name of the test
• Set up "Build project" instead of just "Build" in the settings of the method's launch

Any idea what I can try else?

Here is the code:

    @Before
    public void setUp() throws Exception {
        restoreJiraData();
        executeSql();
    }

    @Test
    public void testSomething() {
        JqlQueryBuilder osGiComponentInstanceOfType = ComponentAccessor.getOSGiComponentInstanceOfType(JqlQueryBuilder.class);
        Query query = osGiComponentInstanceOfType.newBuilder().where().addFunctionCondition("issue", "grid", DEFAULT_GRID_NAME, "astring like 'test string 1'").buildQuery();
        SearchResults results = jiraCompatibilityHandler.search(query, PagerFilter.getUnlimitedFilter());
        List<Issue> issues = results.getIssues();
        assertEquals(2, issues.size());
    }

    private void executeSql() throws URISyntaxException, IOException {
        File sqlFile = fileResourceService.getFile(SQL_BEFORE_FILE_PATH);
        sqlExecutor.executeSQL(sqlFile);
    }

    private void restoreJiraData() {
        if(needToRestoreJira()) {
            RestoreJiraData restoreJiraData = new SmartRestoreJiraData();
            restoreJiraData.restore(BACKUP_PATH);
        }
    }

    protected boolean needToRestoreJira() {
        final String importFolder = "jira" + File.separator + "home" + File.separator + "import";
        final File root;
        try {
            root = fileResourceService.getFile("").getParentFile();
        } catch (URISyntaxException e) {
            return false;
        }
        return FileUtils.listFiles(new File(root, importFolder), ZIP_EXTENSION, false).isEmpty();
    }
}

Answer 1

Ok, I figured out what was the problem.

It was a problem neither with Intellij, nor with JUnit. The problem was in OSGI. I forgot to add a class from my plugin to my Test plugin's import. As the consequence, it failed to build the service.
