Not sure how to use mock-kue

atlantageek commented 8 years ago

Trying to understand how to use mock-kue. The README says just require it. But I only want to use it during testing. Do I put an if statement around it or what? Or does mock-kue realize its running in a test environment and it doesnt look like it overrides the createQueue function. CreateQueue requires redis to be running on the PC. Is this expected.

From looking at the source code, this does not mock a Redis connection. i.e. createQueue will still throw something like:

Error: Redis connection to 127.0.0.1:6379 failed - connect ECONNREFUSED 127.0.0.1:6379
at Object.exports._errnoException (util.js:1026:11)
    at exports._exceptionWithHostPort (util.js:1049:20)
    at TCPConnectWrap.afterConnect [as oncomplete] (net.js:1081:14)

If you provide a connection, then mock-kue will wrap around the Job object. E.g.

// production-code.js
module.exports = {
  createJob: () => {
    require('kue')
      .createQueue()
      .create('some-job', {title: 'some-job-in-production'})
      .save();
  }
}

// test.js
const pc = require('./production-code');
require('mock-kue'); // it must be placed before calling `createJob`

pc.createJob(); // will not enqueue any job because of `mock-kue`

why can't it mock the redis connection as well ?
