Stable, Easy to use, No deploy Limited errors for catch, no reals checks with infrastructure Unit tests Fast (1-20 min), very good stability with retries, trust in components Need real deploy, non trivial test code, extra work for CI Integration tests Mostly stable with retries, High level confidence in multiple units Slow (5-60 min), Need real deploy, non trivial test code, extra work for CI E2E tests Build confidence in entire architecture Very slow (60-240+ min), Need real deploy, Still problem 0- deployments, Can be brittle (even with retries) Ladislav Prskavec - Teststack conference, 4. 6. 2020 70
