Ways to detect if my app is running under Cypress?

[homer3018]

Hello,

I've got an app loading extensive data from S3 in its production setup (docker containers deployed on Kubernetes). I'd like to know if anyone has come up with a reliable way of identifying if the app is running under cypress. Basically if so the app would read some local mocked data that would load way faster than querying S3, hence testing E2E the app a lot faster while ensuring reproducibility (pulling from S3 gets you the latest).

Side question : it looks like cypress 7.7.0 is used, while the latest is 13.1.0. Any reason why is that ?

Thanks ahead of time for the help
