The document discusses various aspects of Symfony2 functional testing tools, including client and crawler utilization. It also details how to mock a PayPal client for testing and configure parameters in services and YAML files. Additionally, it touches on appointment functionalities and testing setups with different configurations.

24. Something is missing

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

26. What is “outside”?
● External API

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

28. What is “outside”?
● External API
● OS services (time)
● Systems that don't exist yet

29. What is “outside”?
● External API
● OS services (time)
● Systems that don't exist yet
● Systems that other people is working on

30. What is “outside”?
● External API
● OS services (time)
● Systems that don't exist yet
● Systems that other people is working on
● Monsters from the inside(legacy code)

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

32. 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

33. 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

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

35. 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);
}
}
}

36. 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);
}
}
}

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

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

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