PHP PHPUnit assertXmlStringEqualsXmlString()用法及代码示例


assertXmlStringEqualsXmlString()函数是PHPUnit中的内置函数,用于断言实际的XML字符串是否等于预期的XML字符串。如果预期的XML字符串与实际的XML字符串相同,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:

assertXmlStringEqualsXmlString(string $expectedXml, 
string $actualXml[, string $message = ''])

参数:此函数接受上述和以下所述的三个参数:

  •  $expectedXmlString:此参数可以是代表期望的XML字符串的任何类型。
  •  $actualXmlString:此参数可以是代表实际XML字符串的任何类型。
  •  $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assertXmlStringEqualsXmlString()函数:

范例1:



PHP

<?php  
use PHPUnit\Framework\TestCase;  
    
class GeeksPhpunitTestCase extends TestCase  
{  
    public function testNegativeTestcaseForassertXmlStringEqualsXmlString() 
    {  
        $expectedxmlString  =  '<foo><bazx></bazx></foo>';  
        $actualxmlString    =  '<foo><baz></baz></foo>'; 
        // Assert function to test whether given  
        // expected xml string is equal to actual xml string 
        $this->assertXmlStringEqualsXmlString( 
            $actualxmlString, 
            $expectedxmlString, 
            "actual xml string is equal to expected xml string"
        );  
    }  
}  
    
?> 

输出:

PHPUnit 8.5.8 by Sebastian Bergmann and contributors.

            "actual xml string is equal to expected xml string"
        );  
    }  
}  
    
?>
