junit中的assert方法全部放在Assert类中，总结一下junit类中assert方法的分类。 1.assertTrue/False([String message,]boolean condition); 判断一个条件是true还是false。感觉这个最好用了，不用记下来那么多的方法名。 2.fail([String message,]); 失败，可以有消息，也可以没有消息。 3.assertEquals([String message,]Object expected,Object actual); 判断是否相等，可以指定输出错误信息。 第一个参数是期望值，第二个参数是实际的值。 这个方法对各个变量有多种实现。在JDK1.5中基本一样。 但是需要主意的是float和double最后面多一个delta的值。 4.assertNotEquals([String message,]Object expected,Object actual); 判断是否不相等。 第一个参数是期望值，第二个参数是实际的值。 5.assertArrayEquals([java.lang.String message,] java.lang.Object[] expecteds, java.lang.Object[] actuals) ; 6.assertNotNull/Null([String

问题 Assume I want to unit test a method with this signature: List<MyItem> getMyItems(); Assume MyItem is a Pojo that has many properties, one of which is \"name\" , accessed via getName() .

If any other properties don\'t match, I don\'t really care for the purposes of this test. If the names match, it\'s a successful test. I would

问题 I\'m using JUnit-dep 4.10 and Hamcrest 1.3.RC2. I\'ve created a custom matcher that looks like the following: public static class MyMatcher extends TypeSafeMatcher<String> { @Override protected boolean matchesSafely(String s) { /* implementation */ } @Override public void describeTo(Description description) { /* implementation */ } @Override protected void describeMismatchSafely(String item, Description mismatchDescription) { /* implementation */ } } It works perfectly fine when run from the
