On Reddit today, someone asked “What is the best kind of testing?” That’s a loaded question.

I replied:

There are layers of software testing (unit, component, system, end to end, user acceptance, etc) and various types (manual, guided, exploratory, crowd sourced, scripted automation, no-code automation). Where you start depends on the scope of the application under test (AUT), the risks involved, etc. I typically 25% of a project budget being allocated to testing…and here it is often 60% of the project effort.

But then someone else added this longer list:

This list is from the Continuous Delivery youtube channel. There is no one “best” they all fill different requirements.
