Question

我正在尝试使用Junit在Spring Boot进行Mockito单元测试。

但是我收到以下错误。我无法弄清楚错误出了什么问题 Codesnippet： https://pastebin.com/RDUXk5QF

public List<JobPartRecentActivity> jobPartRecentActivityList() {

        Date timestamp = new Date();
        JobPartRecentActivity jobData = new JobPartRecentActivity();
        jobData.setCommments("TestComments");
        jobData.setEventId(1234L);
        jobData.setJobNumber(1234L);
        jobData.setTagNumber(1L);
        jobData.setSerialNumber("6789");
        jobData.setPartNumber("12345");
        jobData.setOperationName("Receiving");
        jobData.setOperationSequence(1L);
        jobData.setOperationCode("02");
        jobData.setPartStatus("COMPLETE");
        jobData.setTimestamp(timestamp);
        jobData.setSystemActionTaken("Done");

        List<JobPartRecentActivity> dataList = new ArrayList<>();
        for (int i = 0; i < 3; i++) {
            dataList.add(jobData);
        }

        return dataList;

    }

    @Test
    public void testremoveDuplicateEntries() throws Exception {
        //setup
        List<JobPartRecentActivity> actualdataList = new ArrayList<>();
        Date timestamp = new Date();
        JobPartRecentActivity jobDataActual = new JobPartRecentActivity();
        jobDataActual.setCommments("TestComments");
        jobDataActual.setEventId(1234L);
        jobDataActual.setJobNumber(1234L);
        jobDataActual.setTagNumber(1L);
        jobDataActual.setSerialNumber("6789");
        jobDataActual.setPartNumber("12345");
        jobDataActual.setOperationName("Receiving");
        jobDataActual.setOperationSequence(1L);
        jobDataActual.setOperationCode("02");
        jobDataActual.setPartStatus("COMPLETE");
        jobDataActual.setTimestamp(timestamp);
        jobDataActual.setSystemActionTaken("Done");
        actualdataList.add(jobDataActual);
        //execute
        List<JobPartRecentActivity> expecteddataList = new ArrayList<>();
        expecteddataList = eventEngine.removeDuplicateEntries(jobPartRecentActivityList());
        //verify
        assertThat(actualdataList, is(expecteddataList));

    }
}

Answer 1

您注意将equals和hashcode添加到JobPartRecentActivity，因为断言（...，是（...））;如果对象没有equals和hashcode，则按引用进行比较。

Answer 2

问题在于日期。它正在比较时间戳。当创建expecteddatalist对象并创建了realdatalist对象时，确实存在时差。一旦我们删除了Date代码，断言就可以了。

AssertThat返回匹配List
