Version control is enabled by default and allows teams to collaborate and manage multiple versions of test cases simultaneously while maintaining data integrity and providing a history of changes. Versions can be viewed together and compared for audit purposes.
Changes to testing details only affect test executions using the current version. Changes to test steps do not affect test executions automatically to preserve the results history. However, the following notification appears on the Test Player screen:
You cannot create a new version directly from an older version, but you can make changes to older versions. Also, by default all lists, grids, searches, queries, etc., display the latest version of test cases.
The ability to create new versions can be managed in Project Settings.
