To execute an Engine test you don’t need to write a new Gauntlet test.
You can use the already existing test node named UE.EditorAutomation and UE.TargetAutomation tests to run through the corresponding build targets (Editor and Client).
RunUAT.bat RunUnreal -test=UE.TargetAutomation -runtest=Lyra.MenuStartEliminationSpec -project=Lyra -build=<path to packaged game>The advantage of using the UE.Automation test nodes is the build-in parsing of test output. However for the Client run it will require the Editor too as it will serve as coordinator.
A coordinator is required mainly if you have Screenshot comparison to evaluate.
