PHP PHPUnit assertDirectoryNotIsWritable()用法及代码示例


assertDirectoryNotIsWritable()函数是PHPUnit中的内置函数,用于断言指定的目录是否不是目录或不可写。如果给定的目录路径不存在或不可写,则此断言将返回true,否则返回false。如果为真,则通过断言的测试用例,否则测试用例失败。

用法:

assertDirectoryNotIsWritable( integer $directory, string $message = '' )

参数:该函数接受两个参数,如上面的语法所示。参数说明如下:


  • $directory:此参数是一个字符串,它表示目录路径。
  • $message:此参数采用字符串值。当测试用例失败时,此字符串消息将显示为错误消息。

以下程序说明了PHPUnit中的assertDirectoryNotIsWritable()函数:

程序1:

<?php 
use PHPUnit\Framework\TestCase; 
  
class GeeksPhpunitTestCase extends TestCase 
{ 
    public function testNegativeTestcaseForassertDirectoryNotIsWritable() 
    { 
        $directoryPath = "/home/shivam/Documents/phpunit/notwritable"; 
  
        // Assert function to test whether given 
        // directory path either doesn't exists or not writable 
        $this->assertDirectoryNotIsWritable( 
            $directoryPath, 
            "directoryPath either doesn't exists or not writable"
        ); 
    } 
} 
  
?>

输出:

{ 
    public function testPositiveTestcaseForAssertDirectoryNotIsWritable() 
    { 
        $directoryPath = "/home/shivam/Documents/geeks"; 
  
        // Assert function to test whether given 
        // directory path exists or not writable 
        $this->assertDirectoryNotIsWritable( 
            $directoryPath, 
            "directoryPath either doesn't exists or not writable"
        ); 
    } 
} 
  
?>
