Testing Javascript with Jasmine
11 likes1,880 views
Jasmine is a behavior-driven development framework for testing JavaScript code. It does not depend on any other JavaScript frameworks and does not require a DOM. It has a clean, obvious syntax for writing tests using specs, expectations, suites, matchers, spies, and handling asynchronous code. Jasmine can be used with HTML, Ruby, NodeJS, Java, and other platforms/languages.
![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.](https://image.slidesharecdn.com/jasmine-110606123527-phpapp02/85/Testing-Javascript-with-Jasmine-20-320.jpg)
Testing Javascript with Jasmine

- 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
