Any recommendations of frameworks and learning materials? Ideally, something that could be integrated in the build process. I have mostly found some SaaS services (no-go) and Apache JMeter tutorials mostly aimed at QA (e.g., using GUI mode predominantly) so far.
I have used k6 in our CI/CD pipeline to do integration testing and then ran nightly actions to do smoke and load testing. It was easy to setup and it worked great.
The framework provides a clean way to define expectations and to produce data that can then be visualized in grafana.
