3. Unit = Unit Of Work
Starts with a public entry point
Returns a Value
Changes System State
Calls a 3rd party system
RTFM

4. Unit Testing vs. TDD
Writing the tests
Vs.
When to write them

5. TDD is NOT about testing
It is about
Driving development
Plays a role in design and aesthetics
Focus
Productivity
Incremental Delivery & early Feedback

6. I do not use TDD to test the whole
system
Create a skeleton of a working system
Simple use cases, simplest inputs
Drive development
Rest is covered by
Integration tests
Acceptance Tests

7. I do not use TDD if
I am working on a proof of concept
One-off that is short lived, or easy to maintain
and fix without tests
Startup with min. viable product

8. I do use TDD if
I am working on code that someone else might
have to maintain at some point
I know this code will leave in this application for
more than a week

12. Looks like you’re doing fine

14. Bad Test

15. All around me are familiar classes
No test passes
No test passes

16. And I swear they passed the day before
They passed before
What are you crying for

17. And I find it kind of funny
I find it kind of sad
If we didn’t catch this early
Then project would be dead

18. I think the test had saved us
But my manager disagrees
There are clients running circles
It’s a very very

19. Bad test
I’m stressed
He’s not impressed

20. There’s a testing framework I am using
It was hard choosing
And very confusing

21. And there are many mocking frameworks to
choose from
I tried them all
And It’s killing my soul

22. And I find it kind of funny
I find it kind of sad
The tests that I’ve been writing
Are the worst I’ve ever had

23. I find it hard to tell him
Afraid that he will see
I am hiding from my dev lead
It’s a very very

24. Bad test
I’m stressed
He’s not impressed
BAD TEST
