[转]Hamcrest使用方法实例

assertThat方法需要使用hamcrest的匹配方法：
示例
assertThat( n, allOf( greaterThan(1), lessThan(15) ) );
assertThat( n, anyOf( greaterThan(16), lessThan(8) ) );
assertThat( n, anything() );
assertThat( str, is( "bjsxt" ) );
assertThat( str, not( "bjxxt" ) );
assertThat( str, containsString( "bjsxt" ) );
assertThat( str, endsWith("bjsxt" ) );
assertThat( str, startsWith( "bjsxt" ) );
assertThat( n, equalTo( nExpected ) );
assertThat( str, equalToIgnoringCase( "bjsxt" ) );
assertThat( str, equalToIgnoringWhiteSpace( "bjsxt" ) );
assertThat( d, closeTo( 3.0, 0.3 ) );
assertThat( d, greaterThan(3.0) );
assertThat( d, lessThan (10.0) );
assertThat( d, greaterThanOrEqualTo (5.0) );
assertThat( d, lessThanOrEqualTo (16.0) );
assertThat( map, hasEntry( "bjsxt", "bjsxt" ) );
assertThat( iterable, hasItem ( "bjsxt" ) );
assertThat( map, hasKey ( "bjsxt" ) );
assertThat( map, hasValue ( "bjsxt" ) );
 
Failure和Error
Failure是指测试失败
Error是指测试程序本身出错
JUnit4 Annotation
@Test: 测试方法
(expected=XXException.class)
(timeout=xxx)
@Ignore: 被忽略的测试方法
@Before: 每一个测试方法之前运行
@After: 每一个测试方法之后运行
@BeforeClass: 所有测试开始之前运行 //必须定义为static方法
@AfterClass: 所有测试结束之后运行   //必须定义为static方法
