A presentation on mocking and isolation frameworks in the .net space.

1. A Mockery of a Presentation Gil Zilberfeld Typemock

2. Who am I? Software developer for 15 years Technical Evangelist at Typemock @gil_zilberfeld Let me tell you about my first REAL job...

4. We can’t touch a live system When we call the database Setup Teardown Repeat

6. Really…

7. What do I need? A mock? A stub? A fake? A test double?

8. Mocks aren't stubs!

9. Modern Tests AAA Arrange Act Assert

10. AAA Demo

11. Mocks vs. stubs don't matter in AAA world, so let's use fake

12. Fakes help me change behavior without changing the code

13. Fakes help me verify calls

15. Override virtual methods

17. 41%

20. What are the differences?

21. My name is Gil andI did not use a framework I used hand rolled fakes until it became complicated and I stopped unit testing I knew about isolation frameworks, read about them, but thought they were too complicated

22. My name is Gil and I was an idiot (I'm better now)

23. Unit tests are the antidote to stupid bugs it's impossible to stick with unit testing without fakes It's a waste of time using hand rolled mocks

24. Start now It's a productivity tool Make it part of your tool belt
