PHPUnit assertNotIsReadable()函数
assertNotIsReadable()函数是PHPUnit中的内置函数,用于断言assertNotIsReadable指定的文件名是否不可读。如果给定的文件名不可读,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:
assertNotIsReadable(string $filename[, string $message = ''])
参数:该函数接受上面提到的两个参数,如下所述:
- $filename:这个参数是一个字符串,表示文件名。
- $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。
