A modern load testing tool, using Go and JavaScript
...Verify that applications can handle the expected traffic. Adapt your testing: stress tests, peak tests, soak tests, etc. Mix browser and API testing—interact with real browsers and collect frontend metrics to get a holistic user view. Simulate real-world traffic in your chaos experiments. Inject system failures in your k6 tests.
Lightweight service virtualization/ API simulation / API mocking tool
...Replace unreliable test systems and restrictive API sandboxes with high-performance simulations in seconds. Run on MacOS, Windows or Linux, or use native Java or Python language bindings to get started quickly. Simulate API latency or failure when required by writing custom scripts in the language of your choice.
Katas are fun but they are usually limited in their scope for learning a language; you're unlikely to use goroutines to solve a kata. Another problem is when you have varying levels of enthusiasm. Some people just learn way more of the language than others and when demonstrating what they have done end up confusing people with features the others are not familiar with.
