From website copy as cURL, import to postman and run.
Simple, fast, sorts out the authentication and then allows experiments.
Example: I was testing a search feature under a logged in state on a website.
Easy way to do exploratory testing on the search call, see all the data in a decent format that may not be used or displayed by the front end and then do rapid experiments from there.
Going from website to postman and running about 20 test scenario’s and finding bugs in 5 mins. That’s my go-to.
