 | `QA_COOKIES` |-  | Optionally set to "cookie1=value;cookie2=value" in order to add a cookie to every request. This can be used to set the canary cookie by setting it to "gitlab_canary=true", or to use a different cell e.g. "_gitlab_session=cell-2-please". | No|
-| `QA_DEBUG` |-  | Set to `true` to verbosely log page object actions. Note: if enabled be aware that sensitive data might be logged. If an input element has a QA selector with `password` in the name, data entered into the input element will be masked. If the element doesn't have `password` in its name it won't be masked. | No|

 | `QA_LOG_PATH` | `QA_ARTIFACTS_DIR` | Path to output debug logging to. | No|
