PHP PHPUnit assertFileNotEquals()用法及代码示例

assertFileNotEquals()函数是PHPUnit中的内置函数，用于断言实际文件内容是否与预期文件内容不同。如果预期文件内容为not-equals到实际文件内容，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:

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

参数：此函数接受上述和以下所述的三个参数：

$expected:此参数是代表预期文件路径的字符串类型。
$actual:此参数是代表实际文件路径的字符串类型。
$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。

以下示例程序旨在说明PHPUnit中的assertFileNotEquals()函数：

范例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"
        );  
    }  
}  
    
?>
