Is there a way to effectively test Apollo Server subscriptions with jest?

While working on integration tests with apollo-testing-library, I found that I could mutate and query but not subscribe and test. Can anyone share any innovative techniques or know how to mock a subscription in Jest?

Answer №1

I may be arriving late to the party, but I wanted to share my solution for anyone facing a similar challenge.

In my case, I tackled the issue with an all-encompassing End-to-End test focused on subscriptions.

This involved:

  • Launching my existing graphql server
  • Setting up an apollo client in node
  • Implementing subscriptions within my test

If you're interested, I've provided a sample gist here:
