Lines 151 to 153 in 7c08905

	if (process.env['NODE_ENV'] !== 'test') {
	run()
	}

Since NODE_ENV is a reserved environment variable in this action, this should be mentioned in the readme or in a new log.

Excellent point. I think it might make more sense for me to use a more specific env var, to avoid any collisions. I'll get this sorted out soon. Thanks for suggesting!
