PHP PHPUnit assertXmlFileNotEqualsXmlFile()用法及代码示例

assertXmlFileNotEqualsXmlFile()函数是PHPUnit中的内置函数，用于断言实际的XML文件内容是否不等于预期的XML文件内容。如果预期的XML文件内容与实际的XML文件内容不同，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:

assertXmlFileNotEqualsXmlFile(string $expectedFile, 
string $actualFile[, string $message = ''])

参数：此函数接受上述和以下所述的三个参数：

$expectedFile:此参数可以代表期望的XML文件路径的任何类型。
$actualFile:此参数可以是代表实际XML文件路径的任何类型。
$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。

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

class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForassertXmlFileNotEqualsXmlFile() 
    {  
        $actualFile =  '/home/lovely/Documents/php/actual.xml'; 
        $expectedFile    = '/home/lovely/Documents/php/expected.xml';  
        // Assert function to test whether given  
        // expected xml file is not equal to actual xml file 
        $this->assertXmlFileNotEqualsXmlFile( 
            $actualFile, 
            $expectedFile,  
            "actual xml file is not equal to expected xml file"
        );  
    }  
}
