Hello @kentcdodds , In the README, we have specified that we could use the extend assertions by importing: ``` import 'react-testing-library/extend-expect' ``` infact this throws an error: ``` Cannot find module 'react-testing-library/extend-expect' from 'HelpTest.js' ``` only the below works: ``` import 'react-testing-library/dist/extend-expect' ``` Will debug this and let you know whats happening here.
