Redeploy a Phase
Reopening a phase for another testing pass.
Select the phase in the project's Assigned or Optional section to open the Testing Phase page, then select View Progress.
Go to the Test Cases or Regression tab that contains the failed case — you can't redeploy from a tab that has no failed case, even if another tab does. Then select Redeploy Testing Phase in the bottom-right of the screen.
Redeploying resets only the cases with failed results and requires all testers to redo those cases, regardless of the result they originally submitted.
