[QUESTION] Integration with Jest - Schema hasn't been registered for model #793

gustavovendramini · 2020-04-01T11:45:26Z

How to load Ts.ED schemas outside the server context?

I'm writing tests with Jest and I`m receiving this:

● Test suite failed to run
 
    MissingSchemaError: Schema hasn't been registered for model "Spirit".
    Use mongoose.model(name, schema)

I have tried with const SpiritModel = mongoose.model('Spirit') as MongooseModel<Spirit> but no sucess.

I'm using Typescript 3.8.3, Ts.ED 5.44, Jest/ts-jest 25.x and express 4.17

mytest.test.ts

import "@tsed/mongoose";
import { MongooseModel } from "@tsed/mongoose";
import * as mongoose from 'mongoose';
import { Spirit } from '../src/models/Spirit';

const SpiritModel = mongoose.model('Spirit') as MongooseModel<Spirit>

test('get a wild spirit', async () => {
  expect.assertions(1);
  const spirit = await SpiritModel.findOne({ wild: true, power: 1, state: '' }).exec();
  expect(spirit?.wild).toBe(true);
})

package.json

"scripts": {
    "test": "TS_TEST=true jest"
  },

jest.config.js

module.exports = {
  preset: 'ts-jest',
  testEnvironment: 'node',
  setupFiles: ['dotenv/config'],
  roots: ['tests'],

  globals: {
    'ts-jest': {
      tsConfig: 'tsconfig.json'
    }
  },
  verbose: true,
  collectCoverage: true,
  moduleFileExtensions: ['ts', 'js', 'json'],
  testMatch: ['**/tests/**/*.test.ts'],
  testEnvironment: 'node',
  testPathIgnorePatterns: ['<rootDir>/node_modules/', '<rootDir>/out/'],
  modulePathIgnorePatterns: ['<rootDir>/node_modules/', '<rootDir>/out/'],
  coverageDirectory: 'tests/result',
  collectCoverageFrom: [
    'src/controllers/**/*.ts',
    'src/middlewares/**/*.ts',
    'src/services/**/*.ts',
    '!**/*.d.ts'
  ]
};

Hello @gustavovendramini
Have your looked this page : https://tsed.io/tutorials/mongoose.html#testing-model

It should solve your problem :)

See you

@Romakita That not worked for me ...

But I followed @striquer tip and it worked

import { createSchema, createModel } from "@tsed/mongoose";
import { Character } from "../src/models/Character";
import { Document } from "mongoose";
import { MongooseService } from "../src/services/MongooseService";
import { States } from "../src/interfaces/States";

const characterSchema = createSchema(Character, { schemaOptions: { _id: false } });
const CharacterModel = createModel<Character>(Character, characterSchema, 'Character', 'characters');

beforeAll(() => {
    return MongooseService.connect(process.env.MONGO_CONNECTION_URL, {
        useNewUrlParser: true,
        useCreateIndex: true,
        useFindAndModify: false,
        useUnifiedTopology: true,
        poolSize: 40
    });
});

afterAll(() => {
    return MongooseService.get().connection.close()
});

test('Character state its NORMAL', async () => {
    expect.assertions(1);
    const character = await CharacterModel.findOne({ name: 'Grace' }).exec() as Character & Document;
    expect(character.state).toBe(States.NORMAL);
})

Ha ook :)
But you create a connection on a physical mongo db.
It strange. Because the TestMongooseContext is here to solve this problem, and I have some unit test on mongoose model which is works.

import {TestMongooseContext} from "@tsed/testing-mongoose";
import { MongooseModel } from "@tsed/mongoose";
import { Spirit } from '../src/models/Spirit';

describe("SpiritModel", () => {
  beforeEach(TestMongooseContext.create);
  afterEach(TestMongooseContext.reset);

  it("get a wild spirit", TestMongooseContext.inject([SpiritModel], async (model: MongooseModel<SpiritModel>) => {
      // GIVEN - Create and add data to the mocked database
      const spirit = new SpiritModel({ wild: true, power: 1, state: '' }); 
      await user.save();

      // THEN - Get the data in the mocked database
      const result = await SpiritModel.findOne({ wild: true, power: 1, state: '' }).exec();
      expect(result?.wild).toBe(true);
  }));
});

I think when you have tested the solution given document, you've missed to populate the mocked database befare run the findOne() method :)

See you
