Stubbing

An example with Paypal

namespace JMS\Payment\PaypalBundle\Client;

class Client { [...] public function request(Request $request) { [...] // perform the request if (false === $returnTransfer = curl_exec($curl)) { throw new CommunicationException( 'cURL Error: '.curl_error($curl), curl_errno($curl) ); } [...] $response = new RawResponse( substr($returnTransfer, $headerSize), curl_getinfo($curl, CURLINFO_HTTP_CODE), $headers ); curl_close($curl); return $response; }}





namespace ACME\PaymentBundle\Tests\Stub;

use JMS\Payment\PaypalBundle\Client\Client;

class PaypalClientStub extends Client { public function request(Request $request) { $response = new RawResponse( "TOKEN=BlaBlaBlaBla", 200, array( 'Date' => "Fri, 07 Sep 2012 15:21:00 GMT", 'Server' => "Apache", ) ); return $response; }}

namespace ACME\PaymentBundle\Tests\Stub;

use JMS\Payment\PaypalBundle\Client\Client;

class PaypalClientStub extends Client { public function request(Request $request) { $response = new RawResponse( "TOKEN=BlaBlaBlaBla", 200, array( 'Date' => "Fri, 07 Sep 2012 15:21:00 GMT", 'Server' => "Apache", ) ); return $response; }}

services.xml

JMS\Payment\PaypalBundle\Client\Client

config_test.yml

parameters: payment.paypal.client.class: ACME\PaymentBundle\Tests\Stub\PaypalClientStub


class Client { [...] public function getAuthenticateExpressCheckoutTokenUrl($token) { $host = $this->isDebug ? 'www.sandbox.paypal.com':'www.paypal.com';

return $host; }}

namespace ACME\PaymentBundle\Tests\Stub;use JMS\Payment\PaypalBundle\Client\Client;

class PaypalClientStub extends Client { public function getAuthenticateExpressCheckoutTokenUrl($token) { return '/payment/paypalFakeController'; }}


class PaypalClientStub extends Client { public function request(Request $request) { if ($request->request->get('METHOD') == 'SetExpressCheckout') { $response = new RawResponse( "TOKEN=BlaBlaBla", ); } elseif ($request->request->get('METHOD') == 'GetExpressCheckoutDetails'){ $response = new RawResponse( "CHECKOUTSTATUS=PaymentCompleted&ACK=Success", ); } elseif ($request->request->get('METHOD') == 'DoExpressCheckoutPayment'){ $response = new RawResponse( "PAYMENTINFO_0_PAYMENTSTATUS=Completed", ); } return $response; }}





Something is missing

Control on the request


class PaypalClientStub extends Client { public function request(Request $request) { if ($request != "OK STUFF") { throw new Exception ("Wrong Request for Paypal call"); } [...]

return $response; }}

The date/time case

A user can see the next three appointments

The date/time case


A user is shown an alert in home page if she has an appointment in the next 6 hours

The date/time case


A user is shown an alert in home page if she has an appointment in the next 6 hours

A user can take an appointment for the next day, but if it is Friday the next eligible day will be Monday

namespace ACME\CoreBundle\Service;

class Time{ public static function getNow() { return new \DateTime(); }}

namespace Acme\CoreBundle\Test\Service;

class Time{ public static $referenceTime = '2012-05-01 12:00:00'; public static $time = null;

public static function getNow() { if (is_null(self::$time)) { return new \DateTime(self::$referenceTime); } else { return new \DateTime(self::$time); } }}

namespace Acme\CoreBundle\Test\Service;

class Time{ public static $referenceTime = '2012-05-01 12:00:00'; public static $time = null;

public static function getNow() { if (is_null(self::$time)) { return new \DateTime(self::$referenceTime); } else { return new \DateTime(self::$time); } }}

Use Acme\CoreBundle\Test\Service\Time;

public function load(ObjectManager $manager){ $appointmentToday = new Appointment(); $appointmentToday->setDateTime(new \DateTime(Time::$referenceTime)); [...]}

Inside the fixtures

Use Acme\CoreBundle\Test\Service\Time;

public function test_customerHome(){ Acme\CoreBundle\Test\Service\Time::$time = "2012-06-01";

[...]}

Inside the test

Different config states

$client = self::createClient(array('environment' => 'test_alternative'));
