Enough small talk... This is why I like unit testing so much:
- It forces me to initially focus on functionality.
- It lets me refactor central code bits and see if any dependant projects break because of it.
I have worked on projects where nobody wanted to change stored procedures on the database. Instead new stored procedures were created. Thereby not breaking existing code. - It lets me open up old projects that i don't remember anything about and experiment when fixing an error. It more or less functions as a description and validation of what the application does.
- It feels good when delivering a product knowing that it actually does what you expect of it.
