If you use PHPStorm you might want to check out the built in HTTP Client. I imported all my Postman collections into it. So far I am pretty impressed. It makes writing tests amazingly easy and I can write a long series of calls and debug them all in PHPStorm. The best part about it is that I can run my tests against my LOCAL, DEV, TEST and PROD servers all with one script, which I could never get postman to do correctly.
