PHPUnit | assertDirectoryExists()函数
assertDirectoryExists()函数是 PHPUnit 中的内置函数,用于断言目录路径是否存在。如果给定的目录路径存在,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:
assertDirectoryExists( integer $directory, string $message = '' )
参数:此函数接受两个参数,如上述语法所示。参数说明如下:
- $directory:此参数是一个字符串,表示目录路径。
- $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。
