Junit4 断言新方法

话不多少说，直接上代码

package ASSERTTEST;

import org.junit.Assert;

import org.hamcrest.*;
import org.junit.Test;
import static org.junit.Assert.*;

import java.util.List;
import java.util.Map;

import static org.hamcrest.Matchers.*;

public class MYTEST {

@Test

public void testAdd() {

//一般匹配符

int s = new T().add(1, 1);

//allOf：所有条件必须都成立，测试才通过

assertThat(s, allOf(greaterThan(1), lessThan(3)));

//anyOf：只要有一个条件成立，测试就通过

assertThat(s, anyOf(greaterThan(1), lessThan(1)));

//anything：无论什么条件，测试都通过

assertThat(s, anything());
//is：变量的值等于指定值时，测试通过

assertThat(s, is(2));

//not：和is相反，变量的值不等于指定值时，测试通过

assertThat(s, not(1));

//数值匹配符

double d = 5.0;

//closeTo：浮点型变量的值在3.0±0.5范围内，测试通过

assertThat(d, closeTo(3.0, 0.5));

//greaterThan：变量的值大于指定值时，测试通过

assertThat(d, greaterThan(3.0));

//lessThan：变量的值小于指定值时，测试通过

assertThat(d, lessThan(3.5));

//greaterThanOrEuqalTo：变量的值大于等于指定值时，测试通过

assertThat(d, greaterThanOrEqualTo(3.3));

//lessThanOrEqualTo：变量的值小于等于指定值时，测试通过

assertThat(d, lessThanOrEqualTo(3.4));

//字符串匹配符

String n = new T().getName("Magci");

//containsString：字符串变量中包含指定字符串时，测试通过

assertThat(n, containsString("ci"));

//startsWith：字符串变量以指定字符串开头时，测试通过

assertThat(n, startsWith("Ma"));

//endsWith：字符串变量以指定字符串结尾时，测试通过

assertThat(n, endsWith("i"));

//euqalTo：字符串变量等于指定字符串时，测试通过

assertThat(n, equalTo("Magci"));

//equalToIgnoringCase：字符串变量在忽略大小写的情况下等于指定字符串时，测试通过

assertThat(n, equalToIgnoringCase("magci"));

//equalToIgnoringWhiteSpace：字符串变量在忽略头尾任意空格的情况下等于指定字符串时，测试通过

assertThat(n, equalToIgnoringWhiteSpace(" Magci "));

//集合匹配符

List<String> l = new T().getList("Magci");

//hasItem：Iterable变量中含有指定元素时，测试通过

assertThat(l, hasItem("Magci"));

Map<String, String> m = new T().getMap("mgc", "Magci");

//hasEntry：Map变量中含有指定键值对时，测试通过

assertThat(m, hasEntry("mgc", "Magci"));

//hasKey：Map变量中含有指定键时，测试通过

assertThat(m, hasKey("mgc"));

//hasValue：Map变量中含有指定值时，测试通过

assertThat(m, hasValue("Magci"));
}}

最坑的就是这几个jar 的版本了，，
