php - 在 PHPUnit 中为页面上的 XML 元素测试断言？

Question

我想断言 PHP 页面上 XML 元素中的元素被断言为相等。

进行两次测试的最佳方法是什么。一个在第一个 ip 上，一个在第二个 ip 标签上？

将我的脚趾浸入水中片段:

public function testPPTPRangeChecker(){

echo "Loggin in as the adinistrator";
//Login as the administrator
$client = $this->myLoginAs('adminuser','Testing1!');

echo "The test user has successfully logged in as administrator";
$crawler = $client->request('POST', '/config/19/46');
echo "The site has navigated successfully to the config page";

    $this->assertTag(
        array(
            'tag' => 'ip',
            'content' => '192.168.1.1'
            )
        );

XML

<pptpd>
        <user>
            <name>testuser</name>
            <ip>192.168.1.1</ip>
            <password>testpass</password>
        </user>
        <user>
            <name>testuser2</name>
            <ip>192.168.1.2</ip>
            <password>testpass2</password>
        </user>

    </pptpd>

如果您只需要知道是否存在正确的 IP，您可以使用 xpath。如果您需要确保整个 XML 结构正确，您可以使用 assertEqualXMLStructure。

class MyTest extends \PHPUnit_Framework_TestCase
{
    private $expectedXML = <<<EOF
<pptpd>
        <user>
            <name>testuser</name>
            <ip>192.168.1.1</ip>
            <password>testpass</password>
        </user>
        <user>
            <name>testuser2</name>
            <ip>192.168.1.2</ip>
            <password>testpass2</password>
        </user>

    </pptpd>
EOF;

    public function testMy1()
    {
        $actualXml = $this->expectedXML;

        $doc = new \DomDocument();
        $doc->loadXML($actualXml);

        $xpath = new \DOMXPath($doc);

        $this->assertSame(1, $xpath->query('//pptpd/user[ip="192.168.1.1"]')->length);
    }

    public function testMy2()
    {
        $actualXml = $this->expectedXML;

        $expected = new \DOMDocument();
        $expected->loadXML($this->expectedXML);

        $actual = new \DOMDocument();
        $actual->loadXML($actualXml);

        $this->assertEqualXMLStructure(
            $expected->firstChild->childNodes->item(1),
            $actual->firstChild->childNodes->item(1),
            true
        );
    }
}
