start_canvas(cmd=cmd_input, timeout=long_wait)

Waits for Canvas to open. Application context stored as global _canvas.

Parameters:

Quits Canvas closing error/overwrite windows. Logs stdout and all filtered stderr (stderr not reported by catchTerminalErrors eventHandler.

catchTerminalErrors(obj)

Polls stderr for unexpected terminal output during test execution.

Sometimes the most recent object clicked will have no symbolic or real name so a deque of the most recent objects is logged to aid in debugging.
