Today, we've updated to the newest version of jest in our TypeScript project. We've included jest in our package.json of our project with"jest": "^24.7.1". We've also included "jest-when": "^2.4.0".
When we run now our tests, we get 1531 errors that jest wasn't found:
Cannot find name 'jest'.Cannot find name 'expect'.Cannot find name 'it'. Do you need to install type definitions for a test runner? Trynpm i @types/jestornpm i @types/mochaand then addjestormochato the types field in your tsconfig.and much more.
We include jest in our spec's with import 'jest'; at the top.
Does anyone has an idea what could be the problem?
