I am halfway in the development of a large Flask web application.
Back in the beginning I chose not to use test-driven-development, for learning curve vs project deadline reasons.
Thus these last weeks I had the opportunity to learn more about it, and I am quite exited about starting to use it.
However, regarding I didn't wrap my project with TDD from the start, is there any cons of starting to use it now ?
I would not refactor my entire app, only the new features I am going to design in the near future.
