[NEW TEST] Automated E2E Testing

Use Dockerfiles and docker-compose to allow for E2E tests to be run via GitHub Actions. This will allow for even better tracking of changes to the NestJS Ecosystem and will help others know the E2E tests are working properly

I’ll try to setup for my project and contribute once I figure it out.

Thinking out loud on the E2E Testing example. @jmcdo29 If you have any idea to simplify it, that would be great!

2 Apps Will Be Created

• e2e-example-redis-publisher have a single REST endpoint, which when called will publish an event to redis
• e2e-example-redis-subscriber will listen to the event from redis and save the data in mongoDB. It also expose a single REST endpoint which can be called to retrieve the saved data.

Dockerfile on how to build each apps will be available in their respective folder.

A e2e-testing folder will be added for E2E test scripts

The endpoints of the request will be injected by environment variables.

A single docker-compose.yaml file in the project root

• The apps and the test scripts will be listed here. We’ll let Docker Compose to figure out which apps to bring up when we docker-compose run in GitHub Actions.
