I tried claude code, and it did write some good quality e2e tests but my biggest worry was the full coverage. Its really difficult to quantify e2e test coverage the way developers do unit test coverage. its really impossible. specs is just one artifact just like code is just one of many artifacts that full system wide e2e coverage needs. addng production logs + producton incidents which I tried also give me some sense of full e2e coverage. if you are using claude code for dev and testing both, its like having cake and eat it too. If claude for whatever reason misrepresent or misinterpret a requirement, that will percolate in code and testing as well. having a 3rd party testing tool is appropiate with allthe data flowing in it like specs, legacy tests, prod incidents, code and then perhaps we can expect full unbiased test coevrage. I am not talking about wanna be enterprise apps or hobby apps, i am talking about >v0 enterprise apps that have real customers and real downside if they go down with rich data set of past incidents and not so perfect code but now they are increasingly using agentic ai to produce more non-human code. they need a 3rd party tool that ingest their data, create a KG understanding of their data and prevent crtical bugs leak into production by geenrating small number of high quality high coverage tests.
