I'm having trouble running tests locally, even on HEAD I get a bunch of tests are failing.
I do:

yarn
yarn bootstrap
yarn build 
yarn test

and I get this: https://gist.github.com/larionov/5e052b1de000297f6d14743a1baee327

Also just removing one dependency from shared-utils changes yarn.lock file considerably, updating a lot of dependencies and CONTRIBUTING.md seems to be outdated, there is no yarn clean command.
