Question

请考虑以下PHP代码

static public function IsLicenseValid($domain)
{
    if (empty($domain)) {
        throw new Exception;
    }

    $licenseResponse = Curl::Post(['hostname' => $domain]);

        $Xml     = new XML();
        $xmlTree = $Xml->XMLToTree($licenseResponse);

        if ($xmlTree['is_valid'] == 'true') {
            return true;
        }
    }

    return false;
}

我正在使用PHPUnit编写测试用例来检查上述方法。我能够涵盖所有情况，除了一个域许可证应该在true xml节点中返回is_valid的情况。

REST API非常安全，不接受来自白名单中未列出的IP的请求。如果有人通过非白名单IP发出请求，则API会为false返回is_valid值（这就是我覆盖false的情况）

我知道这可以使用模拟对象完成，但我不确定如何编写一个模拟对象，可以覆盖域名有效的情况。有人可以帮忙吗？

提前致谢

要测试此类，您将模拟Curl :: Post调用，但由于它是内联完成的，因此您需要使用依赖注入来使用模拟。

类别：

class ValidateLicense {
    private $svc;

    // Constructor Injection, pass the IntegratedService object here
    public function __construct($Service = NULL)
    {
        if(! is_null($Service) )
        {
            if($Service instanceof LicenseAPI)
            {
                $this->SetService($Service);
            }
        }
    }

    function SetService(LicenseAPI $Service)
    {
        $this->svc = $Service
    }

    function ValidLicense($domain) {
        $svc    = $this->svc;
        $result = $svc->IsLicenseValid($domain);
        return $result;
    }
}

class LicenseAPI {
    public function IsLicenseValid($domain)  
    {
        if( empty($domain)) {
            throw new Exception;
        }
        $licenseResponse = Curl::Post(['hostname' => $domain]);

        $Xml     = new XML();
        $xmlTree = $Xml->XMLToTree($licenseResponse);

        if ($xmlTree['is_valid'] == 'true') {
            return true;
        }

        return false;
    }
}

测试：

class ValidateLicenseTest extends PHPUnit_Framework_TestCase
{
    // Could also use dataProvider to send different returnValues, and then check with Asserts.
    public function testValidLicense()
    {
        // Create a mock for the LicenseAPI class,
        $MockService = $this->getMock('LicenseAPI', array('IsLicenseValid'));

        // Set up the expectation for the return method 
        $MockService->expects($this->any())
                    ->method('IsLicenseValid')
                    ->will($this->returnValue(true));

        // Create Test Object - Pass our Mock as the service
        $TestClass = new ValidateLicense($MockService);
        // Or
        // $TestClass = new ValidateLicense();
        // $TestClass->SetServices($MockService);

        // Test
        $domain = "localhost";  // Could be checked with the Mock functions
        $this->assertTrue($TestClass->ValidLicense($domain));
    }

    // Could also use dataProvider to send different returnValues, and then check with Asserts.
    public function testInValidLicense()
    {
        // Create a mock for the LicenseAPI class,
        $MockService = $this->getMock('LicenseAPI', array('IsLicenseValid'));

        // Set up the expectation for the return method 
        $MockService->expects($this->any())
                    ->method('IsLicenseValid')
                    ->will($this->returnValue(false));

        // Create Test Object - Pass our Mock as the service
        $TestClass = new ValidateLicense($MockService);
        // Or
        // $TestClass = new ValidateLicense();
        // $TestClass->SetServices($MockService);

        // Test
        $domain = "localhost";  // Could be checked with the Mock functions
        $this->assertFalse($TestClass->ValidLicense($domain));
    }
}
