Most of my job is making sure that valid queries work as expected and invalid ones are rejected and don't break havoc by producing unexpected effects and that the right error messages are displayed so people can correct the query as necessary and that requires a lot of testing and most of it can be done thru postman.

But not everything can be done thru postman, some errors are browser-specific and even by changing the user agent it won't pop up unless you are using the same browser and operating system, that's expected but it gives you a false sense of security. Review collected by and hosted on G2.com.
