Example using Jest and Cypress with TypeScript in a single repo

If you are using Jest and Cypress types in the same project, they might conflict because both test runners use globals like expect. This project shows how to isolate Cypress TypeScript definitions from Jest TS definitions in the same project.

See the root level tsconfig.json and jest.config.js. The Cypress types are isolated from the root in the file cypress/tsconfig.json. The root tsconfig explicitly only includes libs with Jest globals (without Cypress)

Additional information
