What tests go where?

All tests in /integration need to avoid using private APIs and imports. They should pass as if you were running it against ioredis and a live redis server.

While everything in /functional are tests that could be a unit test, or otherwise test internals that isn't directly exposed in the published library.

How to run e2e tests

You'll need an instance of redis running on localhost, on port 6379:

$ docker run --name ioredis-mock -p 6379:6379 --rm redis redis-server --save 60 1 --loglevel warning

Then you can run npm run test:e2e
