Writing Tests for Message-Writing Applications

Application tests are simpler as well. Generally, they just write a message and then respond. Here’s a test used as part of registering users:

video-tutorials/src/app/register-users/register-users.test.js

test('Issues the registration command when user submits good data ', t => {
  const userId = uuid() 
  const attributes = {
    id: userId,
    email: '[e-mail]',
    password: 'adsfasdf'
  }





  return supertest(app) 
    .post('/register')
    .type('form')
    .send(attributes)
    .expect(301)
    .then(res => {
      t.assert(res.headers.location.includes('registration-complete'))
    })
    .then(() => 
      config.messageStore
        .read(`identity:command-${userId}`)
