haredo-test-adapter

This is a test adapter for Haredo. Use with Haredo>=3.0.0

Usage

All original methods are replaced with sinon stubs. You can use them to assert that the methods are called with the correct arguments.

In addition to that there are some helper methods and properties to make testing easier, like callSubscriber which emulates a rabbit message arriving to the subscriber of the specified queue.

Also, some RabbitMQ behavior is being emulated, like the fact that when trying to assert a queue twice with different parameters then the second call will reject with an error.

import { Haredo } from 'haredo';
import { createTestAdapter } from 'haredo-test-adapter';

const adapter = createTestAdapter();

const haredo = Haredo({ adapter, url: process.env.RABBIT_URL });

haredo.queue('testQueue').subscribe((message) => {
  console.log(message);
});

haredo.callSubscriber('testQueue', JSON.stringify({ test: 'test' }));

assert.equal(adapter.createQueue.callCount, 1);
