Bulk edit allows you changing Custom Fields, Tags, Links etc. on multiple test cases at once.
Perform a bulk action
In a project, go to the Test cases section and do the following:
Select test-cases you want to process together by ticking their check boxes on the left.
Bulk actions button will become visible.
Click the Bulk actions button in the top-right corner of test cases list tree area.
Choose the action you want to execute on selected test cases.
Automated test cases specifics
Please keep in mind that by default all the meta information (Custom Fields, Layer, owner, links) is taken from the test results, so if you haven't configured an Upload Policy for your project all your changes might be lost with the next Launch.
