junit常用注解

阅读更多关于 junit常用注解

在junit中常用的注解有@Test、@Ignore、@BeforeClass、@AfterClass、@Before、@After、@Runwith、@Parameters JUnit4的测试类不用再继承TestCase类了。使用注解会方便很多。 @Test 测试方法，在这里可以测试期望异常和超时时间这是两种抛异常的方法举例如下：expected方法期望抛出异常 timeout方法举例：期望在100秒内结束测试，如果100秒内没有结束，则认为测试失败（一般测试执行效率可用timeout方法） @Ignore：忽略的测试方法举例加入@Ignore此方法，在测试时下面这个方法不进行测试（加这个方法是有意义的，比如此方法的功能没有编写完成加入 @Ignore可暂时不对其进行测试） @Before：每个测试方法之前执行（初始化方法），@After：每个测试方法之后执行（释放资源） @BeforeClass：针对所有测试，只执行一次，且必须为static void，在所有的方法之前执行比@Before还要前 @AfterClass：针对所有测试，只执行一次，且必须为static void，在所有的方法之后执行比@After还要后在什么样的情况下是用这两种方法：如果当你做测试的时候，需要取得很耗费时间的资源比如数据库，或者搭建复杂环境的时候用@BeforeClass
