PHP PHPUnit assertDirectoryIsNotWritable()用法及代码示例

assertDirectoryIsNotWritable()函数是PHPUnit中的内置函数，用于断言指定的目录是否为不可写目录。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:

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

参数：此函数接受上述和以下描述的两个参数：

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

class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForAssertDirectoryIsWritable()  
    {  
        $directoryPath = "/home/lovely/Documents/writable";  
    
        // Assert function to test whether given  
        // directory path exists and writable or not
