PHP PHPUnit assertDirectoryIsWritable()用法及代碼示例

assertDirectoryIsWritable()函數是PHPUnit中的內置函數，用於斷言指定的目錄是目錄還是可寫目錄。如果給定目錄路徑存在且可寫，則此斷言將返回true。如果為真，則通過斷言的測試用例，否則測試用例失敗。

用法:

assertDirectoryIsWritable(string $directory[, string $message = ''])

參數：此函數接受上述和以下描述的兩個參數：

$directory:此參數是一個字符串，它表示目錄路徑。
$message:此參數采用字符串值。當測試用例失敗時，此字符串消息將顯示為錯誤消息。

以下示例說明了PHPUnit中的assertDirectoryIsWritable()函數：

範例1：

PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForAssertDirectoryIsWritable()  
    {  
        $directoryPath = "/home/lovely/Documents/writable";  
    
        // Assert function to test whether given  
        // directory path exists and writable 
        $this->assertDirectoryIsWritable(  
            $directoryPath,  
            "directoryPath exists and writable"
        );  
    }  
}  
    
?>

輸出：
