Right now we are using JIRA to cover Test cases needs.
It would be great if Aha could integrate test cases so that they link with Requirements and Features.
Zephyr for JIRA propose test execution which could be an added value.
Integrate Aha! Develop with TestRail
You can now link features and requirements to test cases and track test runs at the sprint level. Then, track the status without leaving Aha! Develop.
