If a user story fails to pass the test, what message will be displayed when trying to promote it?

When a user story fails to pass the test in the context of the Copado deployment process, an error message is typically displayed when an attempt is made to promote it. This error message serves to indicate that there is an issue that needs to be resolved before the user story can proceed to the next stage of the deployment lifecycle.

The purpose of such an error message is to ensure that only validated changes are deployed, which is crucial for maintaining the integrity of the application and avoiding potential issues in the production environment. By providing a clear indication that the promotion cannot occur due to failed tests, it helps developers and teams to quickly identify and address the necessary corrections.

This contrasts with the other options: a warning message might suggest caution but would not prevent advancement; a success message is only shown when tests pass, thus confirming that the story is ready for promotion; and a notification alert is generally used for informational purposes rather than indicating a failure. Hence, the presence of an error message in this context ensures that the users are aware of the failure to meet the testing criteria before promotion can take place.
