Out of all the test management add-ons available in marketplace like Zephyr, Xray, Test Rail, others, does any support the next gen projects in Jira Cloud?
QMetry Test Management for jira supports Next-Gen projects. Here is the link to the app on marketplace.
For further queries about QMetry you can always reach out QMetry support at https://qmetrysupport.atlassian.net/servicedesk/customer/portal/46 .
Currently, next-gen projects do not support Zephyr Test issue type. We have a feature request suggesting the implementation of this ability:
"Xray " and Test Rail, don't support the new Next-Gen projects.
Also, I'd suggest the same as Jack, to contact the Zephyr support, they will be more accurate to provide you with more information about the plan to implement this feature.
Yes, Xray Cloud supports Next-Gen projects.
