I was able to accomplish this by using the sauce_whisk
gem (https://github.com/saucelabs/sauce_whisk)
"SauceWhisk provides an "ActiveRecord" style client for the Sauce Labs RESTful API. If you're not using the Sauce Gem and you want a nice way to interact with our API, give this a try."
During driver
setup retrieve the SauceLabs Job ID - something like @job_id = @driver.instance_variable_get("@bridge").instance_variable_get("@session_id")
Then during teardown I can use SauceWhisk::Jobs.pass_job @job_id
or SauceWhisk::Jobs.fail_job @job_id
to set the status of the job.
