Hello,
The team at RetailMeNot developed a Java SDK for TestRail's API to make it easier to access and consume TestRail's API without having to know the API's inner working. RetailMeNot published the SDK on GitHub today for everyone to use:
https://github.com/RetailMeNot/TestRailSDK
The SDK can also be added to a project via a Maven dependency as explain on the above project page.
Thanks a lot for publishing the SDK! We have many customers who use Java to access TestRail's API and I'm sure other customers will find the SDK very useful. We will also look into listing this and other third-party projects in a separate section on our website in the future.
Thanks.
