5. StubbingAn example with Paypal

6. namespace JMSPaymentPaypalBundleClient;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; }}

9. namespace ACMEPaymentBundleTestsStub;use JMSPaymentPaypalBundleClientClient;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; }}

10. namespace ACMEPaymentBundleTestsStub;use JMSPaymentPaypalBundleClientClient;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; }}

11. services.xml<parameter key="payment.paypal.client.class"> JMSPaymentPaypalBundleClientClient</parameter>config_test.ymlparameters: payment.paypal.client.class:ACMEPaymentBundleTestsStubPaypalClientStub

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

13. namespace ACMEPaymentBundleTestsStub;use JMSPaymentPaypalBundleClientClient;class PaypalClientStub extends Client { public function getAuthenticateExpressCheckoutTokenUrl($token) { return /payment/paypalFakeController; }}

14. namespace ACMEPaymentBundleTestsStub;use JMSPaymentPaypalBundleClientClient;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; }}

17. Something is missing

18. Control on the requestnamespace ACMEPaymentBundleTestsStub;use JMSPaymentPaypalBundleClientClient;class PaypalClientStub extends Client { public function request(Request $request) { if ($request != "OK STUFF") { throw new Exception ("Wrong Request for Paypalcall"); } [...] return $response; }}

19. What is “outside”?● External API

20. What is “outside”?● External API● OS services (time)

21. What is “outside”?● External API● OS services (time)● Systems that dont exist yet

22. What is “outside”?● External API● OS services (time)● Systems that dont exist yet● Systems that other people is working on

23. What is “outside”?● External API● OS services (time)● Systems that dont exist yet● Systems that other people is working on● Monsters from the inside(legacy code)

24. The date/time case● A user can see the next three appointments

25. The date/time case● A user can see the next three appointments● A user is shown an alert in home page if she has an appointment in the next 6 hours

26. The date/time case● A user can see the next three appointments● 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

27. namespace ACMECoreBundleService;class Time{ public static function getNow() { return new DateTime(); }}

28. namespace AcmeCoreBundleTestService;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); } }}

29. namespace AcmeCoreBundleTestService;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); } }}

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

31. Inside the testUse AcmeCoreBundleTestServiceTime;public function test_customerHome(){ AcmeCoreBundleTestServiceTime::$time = "2012-06-01"; [...]}

32. Different config states$client = self::createClient(array(environment => test_alternative));
