PHPUnit assertNotSame()函数
assertNotSame()函数是PHPUnit中的内置函数,用于断言实际获得的值与预期值不同。如果预期值与实际值不同,则此断言将返回 true,否则返回 false。如果为真,则断言的测试用例通过,否则测试用例失败。
句法:
assertNotSame( mixed $expected, mixed $actual, string $message = '' )
参数:此函数接受三个参数,如上述语法所示。参数说明如下:
- $expected:此参数是代表预期数据的任何类型。
- $actual:这个参数是代表实际数据的任何类型。
- $message:此参数采用字符串值。当测试用例失败时,此字符串消息显示为错误消息。
