Jest 覆盖未检测到 node.js 中的某些文件

Question

I'm doing a small project with node, typescript and typeorm. I created some files basically to create appointments and users and created test files. The problem is, i can't make these files to show in jest coverage report. I'll write down the files:

jest.config.js

module.exports = {
  preset: "ts-jest",
  testEnvironment: "node",
  collectCoverageFrom: [
    "**/*.{ts,tsx}",
    "!**/node_modules/**",
    "!**/vendor/**"
  ]

}

src/routes/users.routes.ts

import { Router } from 'express';
import CreateUserService from '../services/CreateUserService';

const usersRouter = Router();

usersRouter.post('/', async (request, response) => {
  try {
    const { name, email, password } = request.body;

    const createUser = new CreateUserService();

    if (!name) {
      return response.status(400).json({ error: 'Name not informed' });
    }
    if (!email) {
      return response.status(400).json({ error: 'Email not informed' });
    }
    if (!password) {
      return response.status(400).json({ error: 'Password not informed' });
    }

    const user = await createUser.execute({
      name,
      email,
      password,
    });

    const { password: userPassword, ...userResponse } = user;

    return response.send(userResponse);
  } catch (err) {
    return response.status(400).json({ error: err.message });
  }
});

export default usersRouter;

src/routes/index.ts

import { Router } from 'express';
import appointmentsRouter from './appointments.routes';
import usersRouter from './users.routes';

const routes = Router();

routes.use('/users', usersRouter);
routes.use('/appointments', appointmentsRouter);

export default routes;

src/routes/users.routes.test.ts

import request from 'supertest';
import { createConnection, getConnection } from 'typeorm';

describe('appointments routes test', () => {
  beforeAll(async () => {
    await createConnection('development');
    await getConnection('development')
      .createQueryBuilder()
      .delete()
      .from('users')
      .execute();
  });
  afterAll(async () => {
    await getConnection('development')
      .createQueryBuilder()
      .delete()
      .from('users')
      .execute();
    const connection = getConnection('development');
    connection.close();
  });

  it('post new user without name', async () => {
    const response = await request('localhost:3333').post('/users').send({});
    expect(response.status).toBe(400);
    expect(response.body).toEqual({ error: 'Name not informed' });
  });
  it('post new user without email', async () => {
    const response = await request('localhost:3333')
      .post('/users')
      .send({ name: 'Gustavo' });
    expect(response.status).toBe(400);
    expect(response.body).toEqual({ error: 'Email not informed' });
  });
  it('post new user without password', async () => {
    const response = await request('localhost:3333')
      .post('/users')
      .send({ name: 'Gustavo', email: 'ga@gmail.com' });
    expect(response.status).toBe(400);
    expect(response.body).toEqual({ error: 'Password not informed' });
  });
  it('post new valid user', async () => {
    const response = await request('localhost:3333').post('/users').send({
      name: 'Gustavo',
      email: 'ga@gmail.com',
      password: '12345',
    });
    expect(response.status).toBe(200);
    expect(response.body).toMatchObject({
      name: 'Gustavo',
      email: 'ga@gmail.com',
    });
  });
});

The command I'm using for jest: yarn jest --coverage --watchAll --no-cache --runInBand

And the result for the coverage:

$ jest --coverage --watchAll --no-cache --runInBand
 PASS  src/routes/appointments.routes.test.ts (6.082 s)
 PASS  src/routes/users.routes.test.ts

Ran all test suites.

As you can see, it ignores completes the users.routes.ts and index.ts. I tried several things but nothing seems to work. Can somebody help me?

Answer 1

I recently ran into a similar issue. Updating to the most recent version of Jest seemed to fix the problem. You can find the docs for using yarn to upgrade a package here yarn v2.x or here yarn v1.x .

只需清除您的笑话缓存： yarn jest --clearCache或npx jest --clearCache 。
