When you use SpiraTest with GitLab, the synchronization plugin synchronizes some fields unidirectionally and other fields bidirectionally. To clarify the details, this article illustrates which fields are synched and in which directions.
The following table (thanks Mark Grossman for your help) lists what synchronizes:
Sync behaviour (after initial sync)
One-way: Gitlab -> Spira
Read-only in SpiraTeam after initial sync
Comments from one side will be added to the comment flow of the other.
Release: Release Name
No longer synced
No longer synced after initial sync. Fields may be changed in both. However, note Milestone Object/Release object link is still maintained.
Linked by Gitlab ID, remains synced for use by Detected Release, Resolved Release and Verified Release
