Repositories and Testing

[AsurasDev]

When deploying Medusa using the npx create-app-medusa command, what appears to be simplified sources are downloaded. These sources correspond to the https://github.com/medusajs/medusa-starter-default repository, unlike the ones found in https://github.com/medusajs/medusa, the collaboration repository. Of course, this makes sense to simplify deployment, but one resource that I find important for ensuring deployment processes are guaranteed are the tests that are not in the simplified repository. Why aren't the tests in the simplified repository? If I wanted to use the full repository for production deployment, is this possible? Is there a guide for this? What is the process for switching from the first repository to the second?
In general, I would like to have a deployment process that integrates tests with either the first or second repository. Since it's a fork of both, it can receive not only customizations but also version improvements from the community, allowing for quick and easy integration.
