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,,

<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.5</version>
