go test fails with difference in outputs

[jameschensmith]

I'm new to this code and I would like to start contributing some of my effort to this project.

On a fresh go get, Some of the tests are returning a common issue with the outputs. I haven't gone too much into the code yet, but the JSON output at the end makes the issue seem a bit clearer. It seems to be with the {"numOutputs":1} field. Whether or not is should be present, I'm not too sure about. I've posted the test results below. If you need any additional information, just let me know. Thanks!
