使用SpringRunner和JUnit的Spring数据持久性进行集成测试-每个测试的虚拟数据都不同

时间：2018-09-08 20:36:37

标签： java junit spring-data-jpa

我不确定标题是否具有足够的描述性。我试图将虚拟数据插入数据库以进行测试，我认为我应该检查虚拟数据是否已按预期保存。令我惊讶的是，某个特定的记录没有持久化，因此我试图找出该记录的问题。最后，我意识到该特定记录没有错。

下面您可以看到有4个测试断言完全相同的事物。其中1个失败3个通过... enter image description here

我认为我在这里缺少一些基本的东西。贝娄是测试代码

如果需要在此说明中添加其他内容，请告诉我。

谢谢！

[编辑] 我正在使用一种变通办法，可以将其视为一种hack，但暂时它会让我继续。 在Junit 4.11及更高版本中，您可以通过以下方式注释测试类来指定一组测试的运行顺序： @FixMethodOrder(MethodSorters.NAME_ASCENDING)

一个空方法@Test public void AAA_WarmUp(){}

将首先运行，然后其他运行为绿色。 不过，我仍然很好奇，因此，如果有人对发生的事情有正确的解释，我将不胜感激。谢谢 [/ EDIT]

1 个答案:

答案 0 :(得分：0)

我唯一想到的是尝试使用Thread.sleep延迟第一次测试。我认为在插入数据和读取数据之间可能会有一些延迟。
