- 35. Continuous Integration …highest priority is to satisfy the customer…
- 37. Quiz / Show hands: How do you get fast feedback? A. Check if it works manually B. Write tests C. Wait for QA to open a ticket
- 38. Continuous Integration = Fast feedback Check all software changes continuously Continuously = runs on every commit Does the software still work?
- 39. Continuous Integration - Examples Fail build when script has syntax errors Fail build when code is invalid Fail build when content is invalid Fail build when expectations are not satisfied
