Parallelize Cypress

Question: Can this Integrate with a package like knapsack-pro-cypress? · Issue #55 · testdouble/cypress-railsGitHub

Currently we are hitting up close to 20m build times for e2e tests in travis.

We want to use knapsack pro to split this up - but the main problem is the support for this uses a direct call to the npm module cypress - while the rake task is needed to setup the db / server (and not automatically called by the knapsack integration).

It would be nice to solve this problem.
