Packer has the option to write build results to a manifest post-build. See https://www.packer.io/docs/post-processors/manifest.

After writing a few tests for some packer builds, I tend to build my artifact first, then test it. I can have packer write that manifest file, but I continue to have to lug around boilerplate to properly parse the manifest file. It would be nice if terratest came with a helper function that could parse this file and pull an artifactId based on build name.

Thoughts, concerns? Am I missing something?
