问题 The title pretty much explains what I'm facing. I'm trying to test a React component that has some state, and I attempt to provide my store to the component in order to get what it needs.

I went so far as to follow another guide for setting up this environment from scratch and still received this issue with my code. Dependencies include...

问题 I am struggling with this jest error and have no idea how to fix it. Basically I ran the following commands to switch to new babel 7 : npx babel-upgrade --write --install npm install --save-dev @babel/preset-react npm install babel-polyfill Here is my package.json where all of the configs are specified (no .babelrc , no jest.config.js ): { "name": "seqr", "version": "0.2.0", "homepage": "", "devDependencies": { "@babel/cli": "^7.0.0", "@babel/core": "^7.0.0", "@babel/plugin-proposal-class
