@kendallgassner Please review when you got some time. I don't have access to add circle ci as part of the prs, but this should add the yarn test as part of the master circle ci at least. Also, i noticed that the yarn test command was failing because the snippets did not have json format as it was merged here https://github.com/intuit/accessibility-snippets/pull/44 (maybe something got updated later and reverted the changes). Anyway, i renamed it back so now yarn test is passing

I renamed them back to the old file name. I wasn't sure why we changed the file type but the files are actually referenced in the package.json so we will need to update the name there as well

@kendallgassner I've updated the package.json file names and re-tested that yarn test works
