Jest Test

Running yarn test results in the following output:

yarn test v0.18.1
$ jest
 PASS  ./test.js
  console
    ✓ logs to the console (1ms)

We should be seeing testing console log pop up somewhere. Updating the jest configuration in package.json to include "testEnvironment": "node" instead of the default jsdom results in:

yarn test v0.18.1
$ jest
 PASS  ./test.js
  console
    ✓ logs to the console (2ms)

This includes the console.log output we'd expect to see.
