This repo is to replicate a project using winston as its logger

This repo is to replicate how a project works when winston is used for logging and jest at master. I believe this is a regression because [email protected] works with this setup.

What I think is happening

It seems that there's a bug in BufferedConsole in jest-util. Internally, winston uses console._stdout.write when you log. I don't have enough context on how jest overrides the global console object but I know jest does this so that it can defer logging in getConsoleOutput.

Steps to verify

With [email protected]

1. Run yarn to install deps
2. Run yarn test
3. Verify tests pass

With jest@master

1. Build jest locally
2. cd into jest/packages/jest-cli in your local version of jest and run yarn link
3. cd back into this project and run yarn link jest-cli
4. Run yarn test
5. Verify tests fail
