PHP PHPUnit assertFileNotEquals()用法及代碼示例

assertFileNotEquals()函數是PHPUnit中的內置函數，用於斷言實際文件內容是否與預期文件內容不同。如果預期文件內容為not-equals到實際文件內容，則此斷言將返回true，否則返回false。如果為真，則通過斷言的測試用例，否則測試用例失敗。

用法:

assertFileNotEquals(string $expected, string $actual[, string $message = ''])

參數：此函數接受上述和以下所述的三個參數：

$expected:此參數是代表預期文件路徑的字符串類型。
$actual:此參數是代表實際文件路徑的字符串類型。
$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。

以下示例程序旨在說明PHPUnit中的assertFileNotEquals()函數：

範例1：

PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForassertFileNotEquals()  
    {  
        $expected = "/home/bittu/Documents";  
        $actual = "/home/bittu/Documents";  
    
        // Assert file not equal function to test whether expected  
        // file content is different to actual file content or not  
        $this->assertFileNotEquals( 
            $expected,  
            $actual,  
            "actual file content is equals to expected file content"
        );  
    }  
}  
    
?>

輸出：

        // file content is different from actual file content or not  
        $this->assertFileNotEquals( 
            $expected,

        );  
    }  
}
