PHPUnit assertIsWritable()函数

assertIsWritable()函数是 PHPUnit 中的内置函数,用于断言 assertiswritable 是否指定文件名可写。如果给定的文件名存在并且可写,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:

assertIsWritable(string $filename[, 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:

  • $filename:此参数是表示文件名的任何类型的字符串。
  • $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 assertIsWritable()函数:

示例 1:

PHP
assertIsWritable(
            $filename, 
            "filename is writable or Not"
        ); 
    } 
} 
    
?>


PHP
assertIsWritable(
            $filename, 
            "filename is writable or Not"
        ); 
    } 
} 
    
?>
