1. assertThat

需要引入的hamcrest包：hamcrest-all-1.3jar 下载地址：https://code.google.com/p/hamcrest/downloads/list

2. 使用hamcrest的匹配方法

3. 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" ) );

静态引入

import static org.junit.Assert.*;

把类的静态方法引进来
