True TDD​

Our real-time incremental coverage is the first of it’s kind.

Incremental Coverage will filter the coverage to the code that you edited, which means that you can see what impact your latest edits have on your codebase, and if you are really doing TDD, your incremental coverage will always be at 100%.

If you write tests after your code, you will never forget a test!
