I’ve taken to writing .http files which are runnable on a number of IDEs and plugins. I don’t need to know what anybody else is using to run them, they live with the code and I’m happy.
That said, I’ve seen people on QA do really cool end-to-end tests at load via very approachable scripting on Postman.
There’s lots of room for “to each their own” here.
We really all need to get along and accept each others’ opinions. Even if some people are completely wrong and think mutable by default it OK. Hehe.
