Question

这是我的应用程序中测试的样子：

    @Test (expected = UniqueFieldValueConstraintViolationException.class)
    public void testName() {
       Branch b1 = new Branch("tetsname","Test 234","06:00-17:00","098144658");
       Branch b2 = new Branch("tetsname","Test 234","06:00-17:00","098144658");
       db.store(b1);
       db.store(b2);
       db.commit();
     }

虽然引发了异常，但此测试失败：

我该如何避免这种行为？

从堆栈跟踪中，您可以看到testName()方法中没有抛出此异常：它被tests.BranchTests.cleanUp抛出，这可能是在您的真实测试之前或之后运行的单独方法

JUnit的expected不会涵盖这些阶段中抛出的异常。确保这些失败不会在这里发生，或者捕获并忽略它们。

尽管引发了预期的异常，但jUnit测试失败
