 Type `npm run test:e2e` in your command line and see Cypress running for the first time. A folder named `cypress` will be created at the root of your project and a new application window will pop up.

-_Important note_: If you are running Gatsby with the `--https` flag, whether using your own or automatically generated certificates, you will also need to tell `start-server-and-test` to disable HTTPS certificate checks (otherwise it will wait forever and never actually launch Cypress.
