Would it be possible to only mount the tests without building the image?

I was assuming that I could just mount the tests instead of building the cypress image over and over again. Would that be possible?

You can now open Cypress by running: node_modules/.bin/cypress open

Yes, once you build the Docker images, every npm run up just uses the volumes, and does not re-install Cypress

    volumes:
      - ./e2e/cypress:/app/cypress
      - ./e2e/cypress.json:/app/cypress.json
