Using Test Spawn

To test your mod, you can use the Mod Manager's Test Spawn tab (make sure developer settings are enabled in the Manager Config tab) to bypass all menus and put a specific character in any stage or cutscene. You can also specify a save file override or set up a specific position in the stage.
