Testing Times in 2021: Delivering with Confidence
summary
Argues for a deployment pipeline that produces a release candidate and evaluates releasability across commit acceptance and production stages using test driven development, unit and BDD-style executable specs, performance and chaos tests; aims for under five minutes feedback at commit and the whole pipeline under an hour; claims concrete wins — 35,000+ tests at commit and 20,000+ acceptance tests, fivefold stress runs, a real exchange running 13 months before first user-reported defect and a 97% production defect drop at Paddy Power.
