TDD test Spec

loginTest.js

import chai from 'chai';
import chaiHttp from 'chai-http';
import app from '../source/app';

const { expect } = chai;
chai.use(chaiHttp);

describe('/api/v1/auth/login', () => {
    it('should not login with invalid email', (done) => {
      chai.request(app)
        .post('/api/v1/auth/login')
        .send({
          email: 'myemail.com',
          password: 'mypassword',
        })
        .end((err, res) => {
          expect(res).to.be.json;
          expect(res).to.have.status(400);
          expect(res.body.error).to.equal('please provide a valid email');
          done();
        });
    });
 });

The test is descriptive enough and was well written. Good job!

thank you
