between weird LinkedIn influencers urging to delete tests that never failed and Richard’s learnings I know on what team I want to be and whose software I want to use www.youtube.com/watch?v=V_qzqY1bb7I
a slide from Richard Hipp’s “Reliability Lessons From SQLite” talk enumerating:

What Richard Has Learned

• Testability must be a design objective
• 100% MC/DC testing works
• sizeof(tests_cases) >= 10*sizeof(code)
• Approx 10-20% of code used only for testing
• Clear, concise documentation
• Expect to spend most of your time testing
• Good version control - situational awareness
