java - Mockito 和延迟结果

Question

我有一个基于 spring 的项目，我正在努力提高其中的代码覆盖率

我有以下代码块，它在 defferedResult onCompletion 方法上使用了 lambda

        util.getResponse(userInfoDeferredResult, url, userName, password);

    userInfoDeferredResult.onCompletion(() -> {
        //the result can be a String or ErrorResponse
        //if ErrorResponse we don't want to cause ClassCastException and we don't need to cache the result
        if (userInfoDeferredResult.getResult() instanceof String){

            String response = (String) userInfoDeferredResult.getResult();

            cacheServices.addValueToCache(Service.USER_INFO_CACHE_NAME, corpId, response);              
        }
    });

我想知道 - 是否可以使用 mockito 或 powerMockito 模拟 onCompletion lambda 的内容？

Answer 1

将内容提取到新方法:

if(userInfoDeferredResult.getResult() instanceof String) {
     String response = (String) userInfoDeferredResult.getResult();
     cacheServices.addValueToCache(Service.USER_INFO_CACHE_NAME, corpId, response);              
 }

然后这样测试方法？
