rethink-mock

---

A mocking library for unit testing rethinkdb with sinon spies and stubs.

Install

npm install --save-dev rethink-mock

Use

Example

// example using mocha, chai, sinon-chai and proxyquire
const rethinkmock = require('rethink-mock')
const proxyquire = require('proxyquire')
const chai = require('chai')
const expect = chai.expect
chai.use(require('sinon-chai'))
 
describe('userService', () => {
  let userService, r
  beforeEach(() => {
    r = rethinkmock.mock()
    userService = proxyquire('./userService', {
      'rethinkdb': r
    })
  })
  describe('#get', () => {
    it('connects', () => {
      return userService.get('some-id')
        .then(() => {
          expect(r.connect)
            .calledOnce
        })
    })
    it('calls the correct table', () => {
      return userService.get('some-id')
        .then(() => {
          expect(r.table)
            .calledOnce
            .calledWith('users')
        })
    })
    it('calls get with the passed in id', () => {
      return userService.get('some-id')
        .then(() => {
          expect(r.table.get)
            .calledOnce
            .calledWith('some-id')
        })
    })
    it('calls .run with the connection', () => {
      return userService.get('some-id')
        .then(() => {
          expect(r.mock.run)
            .calledOnce
            .calledWith(r.mock.connection)
        })
    })
    it('returns the user', () => {
      const alex = {firstName: 'Alex', lastName: 'DeLarge'}
      r.mock.run.returns(alex)
 
      return userService.get('some-id')
        .then(user => expect(user).to.eql(alex))
    })
  })
})

Options

db: true

By default, .db is missing from the r object. This is because the database is usually selected in the connection and any .db found in the code is probably left over from using the Data Explorer.

If you want to use .db, call .mock({db: true})
