testNG断言

https://junit.org/junit4/javadoc/latest/org/junit/Assert.html#assertThat

断言:Hamcrest - Matchers

对象:
equalTo - 测试对象相等使用Object.equals方法
hasToString - 测试Object.toString方法
instanceOf,isCompatibleType -测试类型 不会,没有验证
notNullValue,nullValue -测试Null
sameInstance - 测试对象示例
集合:
hasEntry,hasKey,hasValue -测试一个map包含一个实体,键或者值
hasItem,hasItems -测试一个集合包含一个元素
hasItemInArray - 测试一个数组包含一个元素
数字:
closeTo - 测试浮点值接近给定的值
文本:
equalToIgnoringCase - 测试字符串相等忽略大小写
equalToIgnoringWhiteSpace - 测试字符串忽略空白
containsString,endsWith,startsWith - 测试字符串匹配
