You don't want to create a completely new test from scratch and rather prefer amending what already works for you? We've just enabled you to do this with our "Duplicate a test" feature.
If you want to duplicate an existing test, click on the 3 dots on the right side of "Invite candidates" and then choose "Duplicate"
You will then be able to replace unavailable tasks or make other changes to your test and save it as a new test.
If you have any additional questions or would like to leave your feedback, please contact us at support@codility.com.
