Current behavior

I have a NestJS app which is using @nestjs/bullmq. I am trying to write some e2e test for my app using the @nestjs/testing. But I get the an error, saying that I do not have a worker. I have a Redis container running in the background¹.

Minimum reproduction code

https://github.com/kasir-barati/bugs/tree/bullmq-worker-needs-connection

Steps to reproduce

Written in the README.md.

Just queue the message as you should be doing it.

Package version

11.0.1

Node.js version

In which operating systems have you tested?

• macOS

Other

I had already asked around and since I was not able to get a straight answer I opened this issue:

• Mocking BullMQ Module for E2E Testing.

• Add support for mocking Redis when in development mode.

• And I also learned that the issue lies in how @Processor decorator is working since if I mock it away it just works. But that's not always the desired scenario, right?

  .overrideProvider(AudioConsumer)
  .useValue({})

  As I shared it here.

• I do not know exactly what is missing in my code right now 😕.

Footnotes

1. I am using Testcontainers and I had written a test case to show that I have a redis container running in the background. ↩

You need BullModule.forRoot
