How to import Postman's collection into SoapUI?
Smartbear developed a postman plugin for Ready!API: https://github.com/SmartBear/readyapi-postman-plugin
Since the question is specifically about SoapUI, here are a few options:
- upgrade to Ready!API;
- get the trial version of Ready!API and import all your collections before the trial expires;
- adapt the source code from GitHub to generate a soapUI project (xml) file from the json postman export.
One thing to note, a project saved in Ready!API can be opened in SoapUI and vice-versa.
