This is a compilation, we've selected statements with no particular rationale other than to put in bold statements that represent an idea shared by at least 3 people.
What have you done differently than usual?
- Run the tests systematically
- I had tests!
- Making classes out of primitives
- Took smaller steps in refactoring, a more structured approach (bigger steps, more mistakes)
- Focusing on details instead of the bigger picture, to start with.
- Lean more on the compiler / IDE
What suprised you the most?
- Amount of thinking involved in OO design
- The plugin auto running unit tests on save
- Code became readable quite quickly
- Not analysing just extracting logic in small steps
- How small the resulting code was
- The power of refactoring tool in Eclipse, what more tooling am I not using!?
- Ease of refactoring when you have 100% coverage and following a few rules
- Ease, fun
- How many different solutions are available for the same problem
Name one question that this workshop has raised
- When is it OK to have getters and setters?
- Is this actually faster than extracting the different cases?
- Why the heck this code works as is!?
- Will this work with our code?
- What more do I need to know to apply this more rigorously?
- I wonder what my design is going to look like using classes with only 2 instance variables
- Amount of work to get 100% coverage
Does it match your expectations?
- Yes, I want to know more
- Yes it is nice to see a design evolve using these small steps
- Expected it to be less difficult
- It was fun
Would this be useful at work? How? Why not?
- We will talk much about it to our colleagues
- Yes it is a better way of refactoring
- If I didn't know the business domain, yes.
- Yes, it helps me figure out how to attack complicated functions in our legacy code
- Yes, our largest "zzz" class suffers a lot from Feature Envy
Miscallaneous
- It would have been good to have a session about how to write tests for this kind of code
- It was a very nice learning experience
As presenters we're particularly fond of that last phrase! A great thanks to all the participants, we had a great time!
If you didn't attend and you would like to know a bit more about this session there's a github repository with the exercise in several languages, along with documentation that'll give you some idea about the content. With Rémy Sanlaville we'll also prepare a screencast with the live demos.
