Experienced CTO-level Rails architect

My name is Jason Fleetwood-Boldt. My specialization is in automated testing.

With codebases tested using automated testing, the engineers write the tests as part of writing the code itself. Automated testing enables solid agile practices like iteration and refactoring with confidence. This is an essential distinction from no-test waterfall development. With untested software and waterfall practices, the developers are constantly afraid of improving any existing code (paying down code debt) because it might break existing functionality.

With automated tested development, both QA (quality assurance) and Product Acceptance are still essential. However, the test suite dramatically reduces the need for regression testing. We know that we have covered existing functionality by the tests we already wrote.
