Sample unit test for model

Is your feature request related to a problem? Please describe. I’m new to Hapi & mongoose and trying to setup unit test for some model I define with Jest, but having found no references on google how to do it properly, so running into some sort of trial and error to make it work.

Describe the solution you’d like One sample unit test where you could run CRUD or call method in a model

Describe alternatives you’ve considered

const Mongoose = require('mongoose')
const RestHapi = require('rest-hapi')
const Config = require('../../config')
const restHapiConfig = Config.get('/restHapiConfig')

// process.env.NODE_ENV = 'development'
const path = require('path')

// we require the handlers directly, so we can test the "Lib" functions in isolation
const Manifest = require('../../config/manifest.conf');
const Glue = require('glue');

describe('unit tests - programs', () => {
  let models

  beforeAll(async (done) => {

    RestHapi.config = restHapiConfig
    RestHapi.config.absoluteModelPath = true
    RestHapi.config.modelPath = path.join(__dirname, '../../server/models')

    models = await RestHapi.generateModels(Mongoose)


    const composeOptions = {
      relativeTo: path.join(__dirname, '../../')
    }

    const manifest = Manifest.get('/')
    const server = await Glue.compose(manifest, composeOptions)

    await server.start()

    done()
  })

  it('should return a report body', async (done) => {

    const logger = RestHapi.getLogger('test').bind()
    const UserData = Mongoose.model('user_program')
    let userData = await RestHapi.list(UserData, {$limit: 1}, logger)
    let reportBody = await models.program.getEvaluationSummary(userData, logger)
    console.log(reportBody)
    expect(reportBody).toBeDefined();
    done()
  });

  afterAll((done) => {
    process.exit(0)
    done()
  });

});

Additional context Above is my trial and it works but could have been better, I guess having a setup.js and not calling generateModels and server.start every time.

Hi @1change, sorry for the late response, life has been busy lately.

Glad you got a working example. For your ‘globalSetup’, are you trying to run an external setup script (like the setup.js you mentioned)? I believe after you register the rest-hapi plugin you need to pass the Mongoose instance back to your test script instead of using a separate require('mongoose'). So maybe something like

const setup = require('setup.js')

...

const Mongoose = await setup()

Also, for the code you posted, since you are using beforeAll it should not have to call server.start and generateModels every time, correct?

Hi @JKHeadley, thx for taking the time. Yes beforeAll won’t call server every time but in every testspec, so having a globalSetup would help.
