Legacy Code Workshop
It was interesting to see how to make testable a legacy code. The "small step" approach is, indeed, useful to make progresses.
However, it was very hard to get the legacy code even to compile, and took a lot of time to get everything fixed.
How to improve:
I think that making everyone working on the same legacy file might be better, since it would be easier to track everyone progress and to help in case of problems.
In this way might be faster to get to something working, so everyone can see the different aspect of the legacy code testing.
Also, might be better to check the source chosen to make the training, so it's not too hard, or too complex to get it done.
