Why

The trusted run feature allows users to automate the approval process for workflows, reducing manual intervention and speeding up the development process. This is particularly useful for workflows with many steps that are safe to automate.

How to test

1. Open the Workspace screen.
2. Start a new run with the trusted run button.
3. Observe that the run automatically approves steps that do not require manual intervention.
4. Observe that the run stops at steps that require manual intervention, and the reason for stopping is displayed on the node.
5. Verify that the trusted run button changes to a stop button when a trusted run is in progress, and clicking it stops the trusted run.
6. Verify that the trusted run feature does not affect the state of the run or the repository if the trusted run is stopped manually.
