I have created a mailing list that sends data to MailChimp. I am wanting to create a small unit or integration test to validate that it is working correctly. I have created a POST route that gets the first name, last name, company and email address of the user. I also have a helper file that contains a mock user and function. The problem is that I am not sure how to test the route. The test is passing but isn't redirecting to the correct route.

signup.js

app.post('/signup', (req, res) => 
 const 
 firstName,
 lastName,
 company,
 email
 = req.body

 const data = 
 members: [
 email_address: req.sanitize(email),
 status: 'subscribed',
 merge_fields: 
 FNAME: req.sanitize(firstName),
 LNAME: req.sanitize(lastName),
 COMPANY: req.sanitize(company)
 
 ]
 

 const jsonData = JSON.stringify(data)

 const options = 
 url: 'https://us20.api.mailchimp.com/3.0/lists/539c805f12',
 method: 'POST',
 headers: 
 Authorization: `auth $MAILCHIMP_API_KEY-us20`
 ,
 body: jsonData
 

 request(options, (err, response, body) => 
 if (err) 
 res.redirect('/')
 else 
 if (response.statusCode === 200) 
 req.flash('secondary', 'Thank you for signing up.')
 res.redirect('/success')
 else 
 res.redirect('/')
 
 
 )
 )

helper.js

module.exports.mockUser = 
 firstName: 'John',
 lastName: 'Doe',
 company: 'Entivik',
 email: 'jdoe@outlook.com'


module.exports.signupUser = async (agent, firstName, lastName, company, email) => agent
 .post('/signup')
 .set('content-type', 'application/x-www-form-urlencoded')
 .send(
 firstName,
 lastName,
 company,
 email
 )

test.spec.js

const chai = require('chai')
const chaiHttp = require('chai-http')
const should = chai.should()
const expect = chai.expect
const app = require('../../app')
const helper = require('./helper')

chai.use(chaiHttp)

describe('test submitted mailing list form', () => 
 it('should return valid form input', async () => 
 const agent = chai.request.agent(app)
 await helper.signupUser(agent, helper.mockUser.firstName, helper.mockUser.lastName, helper.mockUser.company)
 const res = await agent.get('/')
 expect(res).to.have.status(200)
 )
)
