TDD has been around since 2002 but today still too many people out there have little understanding of what it actually is. This slide deck tries to help to understand that TDD is not a method to create tests but a truly genuine way to do programming and that programmers like no other benefit from the technique. Hopefully, this will lead more people to embracing it.

- I spend too much time writing tests.
- TDD Non-TDD Think Test Code Think Code
- Think Test Code Think Code Debug!!!
- In reality Think Test Code
- TDD vs. debugging only Shorter feedback cycle Reusable test suite Code instead of pen and paper Genuine feeling of completeness Predictability
- I spend too much time writing tests. I would have spent this time anyway.
- It doesn’t apply exactly to my case.
- Legacy code
- Front-end
- Embedded systems
- It doesn’t apply exactly to my case. There’s a fair chance my case is not unique.
- I’m new to the technology, I can’t test what I don’t know.
- It’s OK to use a debugger It’s OK to go back and forth
- Test is a hypothesis you can prove on the spot.
- I’m new to the technology, I can’t test what I don’t know. TDD in fact helps me learn.
- I have to modify the code too often, my tests become waste.

- I have to modify the code too often, my tests become waste. Code without tests is non-existing to me.
- My project is too agile, don’t have time for tests! Well…
