PHP PHPUnit assertNotIsWritable()用法及代码示例


assertNotIsWritable()函数是PHPUnit中的内置函数,用于断言assertNotIswritable是否指定了文件名不可写。如果给定的文件名不存在且不可写,则该断言将返回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:

assertNotIsWritable(string $filename[, 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:

  • $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,此字符串消息将显示为错误消息。

以下示例说明了PHPUnit中的assertNotIsWritable()函数:

范例1:



PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForassertNotIsWritable() 
    {  
        $filename = "/home/lovely/Documents/php/phpunit";  
    
        // Assert function to test whether given  
        // file name is not writable  
        $this->assertNotIsWritable( 
            $filename,  
            "filename is not writable"
        );  
    }  
}  
    
?>

输出:

PHPUnit 8.5.8 by Sebastian Bergmann and contributors.

F                                                             1 / 1 (100%)

            $filename,  
            "filename is writable or not"
        );
