Parallelization - Githubissues

Is your feature request related to a problem? Please describe.

The Cypress integration is great and it encourages such tests. However, large applications might have many tests that accumulate long test durations. Currently, our build takes approx. 50 minutes. Most of the time is used by Cypress because parallelization is virtually unachievable. We tried to run multiple docker containers within the build container. That didn't work. We tried to spin up containers in other AWS services. It could work but it comes with a huge amount of complexity. Speeding up our tests is the first thing we did but we have a lot of them. We optimized the tests as far as we could be clicking and typing takes time that we cannot reduce any further. We sped up test runs by running amplify mock inside the build container but the result is almost neglectable.

Describe the solution you'd like What we would love to have is real parallelization of our tests. Other CI tools are well equipped to parallelize tests. We know that Amplify Console is still in its infancy but we consider parallelization to be one of the most important missing features to compete (or at least match) other CI tools.

We would also appreciate any other solution that significantly speeds up our test runs inside the Amplify Console build process.
