Full stack BDD for Symfony2

Many Symfony2 developers have heard about Behat and even use it regularly in their Symfony projects. If you have found value in this tool and the BDD practices it was inspired on, come join us for this talk as we will expand on what other benefits these practices and other BDD tools available can bring. This very illustrative talk will not only present you with the tools but show how to use them together to build beautifully architected, business-oriented Symfony2 applications.

1. Full Stack BDD for Symfony2 Marcello Duarte Konstantin Kudryashov
2. Marcello Duarte Head of Training Konstantin Kudryashov Lead Developer About us
3. • Where are we coming from • Why BDD • Behat Best Practices • Introducing a new tool This talk
4. from Cucumber to
6. Adults don’t think their way into a new way of acting
7. They act their way into a new way of thinking Adults don’t think their way into a new way of acting
8. Ask Why
9. PHPSpec from xUnit to xSpec
10. Test ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?
11. xUnit assert code coverage structure private database mocking
12. Language matter
13. public function testUpdateWithEqualTypes() { $installer = $this->createInstallerMock(); $manager = new InstallationManager('vendor'); $manager->addInstaller($installer); $initial = $this->createPackageMock(); $target = $this->createPackageMock(); $operation = new UpdateOperation($initial, $target, 'test'); $initial ->expects($this->once()) ->method('getType') ->will($this->returnValue('library')); $target ->expects($this->once()) ->method('getType') ->will($this->returnValue('library')); $installer ->expects($this->once()) ->method('supports') ->with('library') ->will($this->returnValue(true)); $installer ->expects($this->once()) ->method('update') ->with($this->repository, $initial, $target);
14. Tools matter
15. Why BDD?
16. [Royce 1970] Requirements Analysis Design Develop Test 9 months 3 months 2 months 12 months ...
17. Most of the cost in software development is in feedback delay
18. Refactoring Code Test Requirements Acceptance ~20 minutes [Beck & Cunningham 1996-99]
19. Let’s reduce feedback delay
20. Let’s rename a few things
21. Incremental Design Implement Describe Object Narratives (Why?) Examples (What do you mean?) How! [North 03]
23. Building a simple Student can enrol on a course feature
24. You can follow our steps http://git.io/t4kQ5Q
25. • No examples until you have a red step • No code until you have a red example • No more code than enough to make it green • Don’t get carried away! BDD Rules
26. • Favour MinkAwareInterface over MinkContext • Extract context per role • Group features under feature folder • Use Mink API • Integrate with framework at config level Behat tips
27. • Describe classes not configuration • Concentrate on messages/behaviours PHPSpec2 tips
28. Questions ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?
