I am currently writing a new test runner for Django and I'd like to know if it's possible to TDD my test runner using my own test runner. Kinda like compiler bootstrapping where a compiler compiles itself.
Assuming it's possible, how can it be done?
Yes. One of the examples Kent Beck works through in his book "Test Driven Development: By Example" is a test runner.
Is it possible to TDD when writing a test runner?
