Therefore, I decided to implement something which was already implemented in other languages before using other infrastructure. This happens in our industry very rarely.
I started to implement the payroll system described in the book Agile Software Development. Originally the payroll system was written in C++ and consist of about 3300 LOC. I implemented the first iteration in ruby writing only 383 LOC including even the test code. I was very surprised. :)
And why did I use rails? Ruby would have been enough.
Simply because it has a very effective development environment.
I used migrate files for creating the relational DB, fixtures for setting up the preconditions for testing, zentest as devil's advocate, and rake for a lot.
What about the benefits:
- it was fun, easy, and very interactive
- I've got fast feedback from zentest
- all the O/R mapping was already done
- learned a lot along the journey
- During the development I was happiest ever
Keep smiling :)
