php:如何在PhpUnit测试中模拟对__soapCall()的SoapClient响应

我有一个RessortSoapService服务,它使用SOAP调用的响应。

我注入一个类,这使我回到了SoapClient:

public function __construct(ParameterBagInterface $params, SapSoapClientInterface $sapSoapClient)
{
    $this->params = $params;
    $this->soapClient = $sapSoapClient
        ->fetchWdslContent($this->params->get('sapwsdlstruktur'))
        ->getClient();
}

在SapSoapClient类中,方法getClient()为我提供了正确初始化的客户端:

public function getClient(): SoapClient
{
    $client = new SoapClient('data://text/plain;base64,' . base64_encode($this->wsdlContent), $this->options);

    return $client;
}

现在,我想编写一个单元测试,它当然不应该调用Soap服务器,而只是伪造一个响应。

这是什么?

class RessortSoapServiceTest extends TestCase
{
    public function setUp(): void
    {
        $this->prepareMocks();
        $this->ressortService = new RessortSoapService($this->params, $this->sapSoapClient);
    }

    private function prepareMocks()
    {
....

        $this->soapClient = $this->createMock(SoapClient::class);

        $this->soapClient
            ->method('__soapCall')
            ->willReturnCallback(
            '<SOAP:Envelope xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP:Header/>
   <SOAP:Body xmlns:urn="urn:sap-com:document:sap:rfc:functions">
      <nm:Z_STA_CUST_GET_RESSORTS.Response xmlns:nm="urn:sap-com:document:sap:rfc:functions" xmlns:prx="urn:sap.com:proxy:PV1:/1SAI/TASC3650D2D2360AAAFB21E:731">
         <ET_RESSORTS>
            <item>
               <GROUP_HIER>0000001</GROUP_HIER>
               <GROUP>0000001</GROUP>
               <IDENT>0000103</IDENT>
               <IS_INACTIVE>0</IS_INACTIVE>
            </item>
... some more XML

         </ET_RESSORTS>
         <ET_RETURN>
            <item>
               <TYPE>S</TYPE>
               <ID>ZSTA</ID>
               <NUMBER>401</NUMBER>
               <MESSAGE>Daten erfolgreich gelesen</MESSAGE>
            </item>
         </ET_RETURN>
      </nm:Z_STA_CUST_GET_RESSORTS.Response>
   </SOAP:Body>
</SOAP:Envelope>'
        );

        $this->sapSoapClient = $this->createMock(SapSoapClientInterface::class);

        $this->sapSoapClient
            ->method('getClient')
            ->willReturnCallback($this->soapClient);
    }

因此,我创建了一个本机SoapClient的模拟程序,我告诉了它,它应该给我一个包含SOAP XML响应的XML字符串,而不是真正联系SoapServer。

当我运行测试__soapCall时,我返回null,因此测试失败。

如何正确模拟__soapCall响应?这是我第一次使用Soap,所以也许我错过了一些细节或了解?

您正在使用willReturnCallback。这期望为实际响应调用一个函数。因此,它尝试查找具有整个xml名称的函数。当然找不到哪个。如果改用willReturn,则应该得到想要的结果。
