Postman and data driven testing

 

Not sure if you have used this, I recently tried this while trying / testing something for my product and it works great.

My need – to have incremental runs of the same test cases / fire the same request, with different data in the request. The data needs to be driven by a CSV file. Didn’t want to write custom java code for this…

Feature Used – Collection Runner of Postman - http://blog.getpostman.com/2014/10/28/using-csv-and-json-files-in-the-postman-collection-runner/

Findings –

· Environmental variables work great within postman

· You can add custom JS code as pre-test steps / post-test steps.

· Recurring runs, with data driven input like CSV files work well with Collection Runner

· You can have results flow from one test case to another and create test flows / sequences.

· You can parse JSON responses and write to Chrome Console, however you need to enable it - http://blog.getpostman.com/2014/01/27/enabling-chrome-developer-tools-inside-postman/ | http://blog.getpostman.com/2016/08/26/the-postman-console/ | https://www.getpostman.com/docs/postman/sending_api_requests/debugging_and_logs

· There is a standalone desktop version with its own console - https://www.getpostman.com/
