1. INTEGRATION TESTING IN A MODERN WORLD
2. WHAT THIS TALK ISN'T ! > Framework Agnostic > A strict TDD regiment > How to do Unit testing
3. WHAT THIS TALK IS ! > Practical Testing > Ways to test against the Database > An awesome new way to assert against your responses
4. OTHER SESSION RIGHT NOW > Web Applications Can Control The World Box Room
5. WHO AM I? ERIC PETERSON > ! Utah > " O.C. Tanner > # 1 wife, 1 kid
6. SO YOU WANT TO START TESTING.... !
7. UNIT TESTING
8. Works really well on individual components. it('calculates the square root', function() { var CUT = new Calculator(); expect(CUT.sqrt(25)).toBe(5); }); !
9. ...not as well when you have collaborator components. it('renders the welcome view', function() { var CUT = getMockBox() .createMock('handlers.Welcome'); var mockService = getMockBox().createMock('models.WelcomeService'); mockService.$('getGreeting', 'Greetings!'); CUT.mockProperty(propertyName = 'service', mock = mockService); var event = CUT.index(); expect(event.getValue('greeting')).toBe('Greetings!'); }); !
10. Here's the same test as an Integration test. it('renders the welcome view', function() { var event = execute(event = 'Welcome.index', renderResults = true); expect(event.getValue('greeting')).toBe('Greetings!'); }); !
11. Before we go any further... PROS AND CONS
12. PROS > Easier to get started with > Makes sure that your application is wired together correctly > Avoids Mocks (which can be really confusing) > High level tests make refactoring easier
13. CONS > Slow > Doesn't really help you do TDD > Really slow > Needs a testing database of some kind > Did I mention slow?
14. IN REALITY?
15. DEMO THE APP
16. DEMO A SIMPLE INTEGRATION TEST
17. PROBLEM Running the test multiple times fails or creates multiple database records
18. DEMO A TESTING DATABASE
19. PROBLEM If we want to use database transactions, we can only make one request Also, the tests are getting kind of messy
20. INTEGRATED HTTPS://GITHUB.COM/ELPETE/INTEGRATED
21. WHAT IS INTEGRATED? > Built on ColdBox (4.2+) and TestBox (2.3+) > Augments the built-in ColdBox Integration test > Easy database transactions across multiple requests > jQuery-style page assertions
22. WHAT IS INTEGRATED? it('renders the welcome view', function() { this.visit('/') .see('Greetings!'); }); !
23. WHAT IS INTEGRATED? it('renders the welcome view', function() { this.visit('/dashboard') .seePageIs('/login') .click('Register') .type('John', 'username') .type('john@example.com', 'email') .type('mY@wes0meP@ssw0rd', 'password') .press('Submit') .seePageIs('/dashboard') .see('Welcome to the team, John!'); }); !
24. DEMO INTEGRATED
25. OTHER SESSIONS AT DEV.OBJECTIVE() CFML Sessions for Dummies Wednesday 3:00 PM to 4:00 PM Live Testing a Legacy App Thursday 1:45 PM to 2:45 PM
