You can see the CI output for example at circleci.com/gh/cypress-io/cypress-example-kitchensink/1187, here is this job executed on 4 machines. We can move our time forward and skip the wait: In this case, we dont really need to pass a Date object to our .clock() function since we are working with a setTimeout() function which will just get moved with the .tick() function and we dont really mind the exact date. once". know your application, so we don't have a lot of specific advice to give you.
