序号	方法和描述
1	void assertEquals(boolean expected, boolean actual) 检查两个变量或者等式是否平衡
2	void assertTrue(boolean expected, boolean actual) 检查条件为真
3	void assertFalse(boolean condition) 检查条件为假
4	void assertNotNull(Object object) 检查对象不为空
5	void assertNull(Object object) 检查对象为空
6	void assertSame(boolean condition) assertSame() 方法检查两个相关对象是否指向同一个对象
7	void assertNotSame(boolean condition) assertNotSame() 方法检查两个相关对象是否不指向同一个对象
8	void assertArrayEquals(expectedArray, resultArray) assertArrayEquals() 方法检查两个数组是否相等

最坑的就是这几个jar 的版本了，，

<dependency>
<groupId>junit</groupId>
<artifactId>junit</artifactId>
<version>4.5</version>
<scope>test</scope>
</dependency>

<!-- https://mvnrepository.com/artifact/org.hamcrest/hamcrest-core -->
<dependency>
<groupId>org.hamcrest</groupId>
<artifactId>hamcrest-core</artifactId>
<version>1.3.RC2</version>
<scope>test</scope>
</dependency>
<!-- https://mvnrepository.com/artifact/org.hamcrest/hamcrest-library -->
<dependency>
<groupId>org.hamcrest</groupId>

<version>1.3.RC2</version>

junit4新用法：

//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"));
}}
