Jest doesn't exit test cases automatically.

[Vijay-CodeAstu]

Hey folks,

here's my configuration:

  "dependencies": {
    "sequelize": "^4.41.1",
    "sequelize-mock": "^0.10.2"
  }

Here is my test case:

const createData = require("../index.js");
const SequelizeMock = require("sequelize-mock");
const dbMock = new SequelizeMock();
const mockData = require('./mock');

describe("Create Data", () => {
  it("Should create data in sequelize", async done => {
    try {
      const result = await createData(mockData);

      expect(result).toBeDefined();
    } catch (err) {
      expect(err).toBeNull();
    }
  });
});

The test case passes, but jest console returns:
Jest did not exit one second after the test run has completed.

It might be something I missed from the tutorial.
Any pointers?

Let me know if I missed something above, I'll share it asap.

Have you tried to call the done method ?

const createData = require("../index.js");
const SequelizeMock = require("sequelize-mock");
const dbMock = new SequelizeMock();
const mockData = require('./mock');

describe("Create Data", () => {
  it("Should create data in sequelize", async done => {
    try {
      const result = await createData(mockData);

      expect(result).toBeDefined();
    } catch (err) {
      expect(err).toBeNull();
    }
    done();
  });
});

can you please what is in mockData?

this is my test.js using jest
jest.mock('../models/cartype', () => () => {
const SequelizeMock = require("sequelize-mock");
const dbMock = new SequelizeMock();
return dbMock.define('cartype', {
cartypename: 'check1'
})
});

this is my sequelize model which i am trying to mock
'use strict';
module.exports = (sequelize, DataTypes) => {
const cartype = sequelize.define('cartype', {
cartypename: {
type: DataTypes.STRING,
allowNull: false,
},
}, {});
cartype.associate = function(models) {
// associations can be defined here
cartype.hasMany(models.car, {
foreignKey: 'cartypeid',
as: 'cartypeid',
});
};
return cartype;
};

here is my decribe of jest
describe("Test Sequelize Mocking", () => {
it("Should get value from mock", async () => {
const cartype = await cartypeController.list();
expect(cartype.cartypename).toEqual('check1');
})
})

i am getting error as below while mocking with sequelize-mock

NODE_ENV=test jest

I am also getting the same type of error.

You will have to jest.mock you car model the same way you did cartype model.
