PHPUnit assertFileIsWritable()函数

assertFileIsWritable()函数是 PHPUnit 的内置函数,用于断言指定的文件是否为可写文件。如果给定的文件名存在且可写,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:

assertFileIsWritable(string $filename[, string $message = ''])

参数:此函数接受两个参数,如上所述,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。

下面的例子说明了 PHPUnit 中的 assertFileIsWritable()函数:

示例 1:



PHP
assertFileIsWritable( 
            $filename, 
            "filename exists and writable"
        );

?>


PHP
assertFileIsWritable( 
            $filename, 
            "filename exists and writable"
        ); 
    }
