nx: Jest26 on Node10 fails with 'ReferenceError: globalThis is not defined' with V8 coverage provider

Current Behavior

CodeCoverage on Node 10 fails when coverage provider is v8

It should work

Generate empty angular application with Nx and update jest.config.js

collectCoverage: true,
cooverageProvider: "v8"

Run npm run test

ng run jestee:test FAIL apps/jestee/src/app/app.component.spec.ts ● Test suite failed to run

@Lonli-Lokli here’s a solution: yarn add jest-environment-jsdom-fifteen --dev Then change your root jest.config.js to have this:

 testEnvironment: "jest-environment-jsdom-fifteen"

That should allow it to work better with Node 10. But we do really recommend that you update to the latest LTS as Node 10 will be EOL next year 😮

I switched to node 12.18.4 and everything was fine.
