Jest test failing

Issue description

• components: any
• reactstrap version #5.0.0-beta.2
• import method es(typescript) (if umd, are you using the “full” version (only for v5+)?)
• react version #16.2.0

What is happening?

Any Jest test in app created by create-react-app fail to run.

Steps to reproduce issue

1. create-react-app my-app --scripts-version=react-scripts-ts
2. npm install --save reactstrap@5.0.0-beta.2 @types/reactstrap
3. import and use any reactstrap component to App.ts, for ex. Container
4. npm run test

Error message in console

  ● Test suite failed to run

    SyntaxError: Unexpected token export

      at Object.<anonymous> (src/App.tsx:15:20)

I don’t think the reason is typescript. As I understood, Jest runs as node process, and create-react-app setup jest to not transpile any files under node_modules folder. Since react-popper/package.json conains "main": "lib/react-popper.js", and version under /lib contains es6’ export statements, node finally gets those export statements and fails. If I change react-popper/package.json to point main to dist: "main": "dist/react-popper.js", tests pass.

Quick fix - revert to “reactstrap”: “5.0.0-beta”. It has older react-popper version.

The PR in react-popper has been merged, just waiting on it to be published in a release.
