For instances where the checklist is on the issue/task card, once the issue is ready for testing and has been deployed then the tester will follow these list ticking off every item as they pass. A list that completely passes has all items in the list ticked off. Where an item in the list fails, this is left unmarked to indicate that it did not pass. Where relevant, additional information will be left in the comment section of the issue/task card. The relevant developer will be alerted and they can follow up, knowing what item failed to pass.
