To run a load test using Postman, first install BrowserUp per these instructions.
Create your collection of tests as normal in Postman
Export the collection to the working directory for your load test:
Test out your collection locally with newman to make sure it works as desired.
Adjust your scenario’s profile(s) to run the collection.
scenario: name: Newman total_users: 20 profiles: - name: Cart API think_time: 10s allocation: 100% command: newman run postman_collections/cart-api.json
browserup load start -d
This will launch a local load test in your Docker environment.
Finally, log into the app and watch the reporting as your load test runs.
Repeat, as needed, with a large-scale load test in Amazon AWS to really put your app through its paces.
Hoppscotch (PostMan Alternative)
BrowserUp also ships Hoppscotch in the standard image. Hoppscotch is an open-source alternative to PostMan that offers similar features.
