Display and Run an LWC from a Quick Action
During active development, use quick actions in the Test Harness app to launch and test
your Lightning web components.
The Test Harness SObjects tab displays a list of all of your org’s sObjects. Tap an sObject in the list to display up to 50 of the most recently viewed records for the selected sObject.
When you tap a record, you’re presented with all of the LWC-based Quick Actions that are defined in Buttons, Links, and Actions in Setup for the selected sObject. Tap a Quick Action to launch the LWC.
