#execute(lane, platform = nil, parameters = nil) ⇒ Object

This will take care of executing one lane. That’s when the user triggers a lane from the CLI for example This method is not executed when switching a lane

Parameters:

  • lane_name —

    The name of the lane to execute

  • platform (defaults to: nil) —

    The name of the platform to execute

  • parameters (Hash) (defaults to: nil) —

    The parameters passed from the command line to the lane
