Presentation about testing Javascript with Jasmine. https://github.com/pivotal/jasmine

1. André Faria Gomes

2. Jasmine is a behavior-driven
development framework for testing
your JavaScript code.

3. It does not depend on any other
JavaScript frameworks

4. It does not require a DOM

5. It has a clean, obvious syntax so that
you can easily write tests.

7. Specs

8. Expectations

9. Suites

10. Nested

11. Disabling
describe => xdescribe
it => xit

12. Matchers
expect(x).toEqual(y);
expect(x).toBe(y); //same
expect(x).toMatch(pattern); //regex
expect(x).toBeDefined(); //not undefined
expect(x).toBeNull();
expect(x).toBeTruthy();
expect(x).toBeFalsy();
expect(x).toContain(y); //for arrays or strings
expect(x).toBeLessThan(y);
expect(x).toBeGreaterThan(y);
expect(fn).toThrow(e);
expect(x).not.toEqual(y);

13. Your Matchers

14. Before & After

15. Spies
Spies are automatically removed after each spec.
They may be set in the beforeEach function

16. Spying Static Methods

17. Spying Instance Methods

18. Spying CallBacks

19. Spying AJAX

20. Spying Matchers
expect(x).toHaveBeenCalled()
expect(x).toHaveBeenCalledWith(arguments)
expect(x).not.toHaveBeenCalled()
expect(x).not.toHaveBeenCalledWith(arguments)
spyOn(x, 'method').andCallThrough(): spies on AND calls the original function spied on
spyOn(x, 'method').andReturn(arguments): returns passed arguments when spy is called
spyOn(x, 'method').andThrow(exception): throws passed exception when spy is called
spyOn(x, 'method').andCallFake(function): calls passed function when spy is called
Spy Properties
callCount: returns number of times spy was called
mostRecentCall.args: returns argument array from last call to spy.
argsForCall[i] returns arguments array for call i to spy.
