According to God of Prompt on X, the largest drain on QA velocity is repetitive, every-sprint regression checks across real user flows like search, navigation, and verification; manual execution adds 2–5 days per release, which compounds to roughly 65 extra days annually for bi-weekly shipping teams (as cited in the linked post). As reported by God of Prompt, Kane AI by TestMu AI (formerly LambdaTest) automates these end-to-end flows on demand, allowing engineers to proceed without manual bottlenecks. According to the same source, this targets brittle test maintenance caused by fast-moving product UIs, suggesting business impact in faster cycle time, lower QA headcount pressure, and earlier feature delivery to customers.
