为什么使用 Mockito 模拟静态方法在我的情况下不起作用？

我有这个复杂的方法。我只想嘲笑结果。里面的所有内容基本上都应该被忽略。我正在使用 Mockito 。

class JiraManager
{
    public static  List<Issue> searchMitarbeiterIssue(String mitarbeiterName) throws JqlParseException, SearchException {
        ApplicationUser user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser();
        JqlQueryParser jqlQueryParser = ComponentAccessor.getComponent(JqlQueryParser.class);
        SearchService searchService = ComponentAccessor.getComponent(SearchService.class);
        String jqlSearchString = "project = BLUB AND issuetype = BLOB AND text ~ \"" + myName+ "\""+" AND status = aktive";
        final Query query = jqlQueryParser.parseQuery(jqlSearchString);
        List<Issue> issues = null;
        Query queryToExecute = JqlQueryBuilder.newBuilder(query).buildQuery();
        // get results for the jql query
        SearchResults searchResult = searchService.search(user, queryToExecute, PagerFilter.getUnlimitedFilter());
        try {
            Method newGetMethod = null;
            try {
                newGetMethod = SearchResults.class.getMethod("getIssues");
            } catch (NoSuchMethodException e) {
                try {
                    LOGGER.warn("SearchResults.getIssues does not exist - trying to use getResults!");
                    newGetMethod = SearchResults.class.getMethod("getResults");
                } catch (NoSuchMethodError e2) {
                    LOGGER.error("SearchResults.getResults does not exist!");
                }
            }
            if (newGetMethod != null) {
                issues = (List<Issue>) newGetMethod.invoke(searchResult);
            } else {
                LOGGER.error("ERROR NO METHOD TO GET ISSUES !");
                throw new RuntimeException("ICT: SearchResults Service from JIRA NOT AVAILABLE (getIssue / getResults)");
            }
        } catch (NoSuchMethodException | IllegalAccessException | IllegalArgumentException | InvocationTargetException e) {
            LOGGER.error("Jql Helper can not get search result (ICT)", e);
        } catch (Exception e) {
            LOGGER.error("Jql Helper can not get search result - other exception (ICT)", e);
        }
        return issues;
    }
}

我不希望 Mockito 运行该方法内的所有代码。它应该只返回 List 。就这样 。所以我尝试了这个：

try (MockedStatic<JiraManager> utilities = Mockito.mockStatic(JiraManager.class)) {
    utilities.when(() -> JiraManager.searchMitarbeiterIssue(any()))
            .thenReturn(Collections.singletonList(mitarbeiterIssueResult));
    assertTrue(JiraManager.searchMitarbeiterIssue("").size() == 1);
} 

但它不起作用。它总是返回 null。为什么 ？？方法内的代码是否被执行？ Mockito 到底在做什么？

下面对我有用。

1. 创建MockedStatic类字段

private MockedStatic<MyUtilClassWithStaticMethods> myUtil;

2. 在每个测试用例之前初始化 MockedStatic

@BeforeEach
void initialiseWorker() {
    myUtil = mockStatic(MyUtilClassWithStaticMethods.class);
}

3. 每个测试用例后关闭 MockedStatic

@AfterEach
public void close() {
    myUtil.close();
}

4. 测试用例中的模拟静态方法行为

@Test
void test() {
    when(MyUtilClassWithStaticMethods.staticMethod(any())).thenReturn(null);
}

您可以在此处返回列表而不是 null。
