Relative URL as hostname in Nock

Question

I need to mock client side HTTP requests. I'm using

isomorphic-fetch

in the client side and I'm using

mocha

and

nock

for testing and mocking. All my client requests are based on relative path. Due to this I'm unable to provide host name for the

nock

. Is there a work around.

Client side:

fetch('/foo') //hostname: http://localhost:8080

.then(res => res.json())

.then(data => console.log(data))

.catch(e => console.log(e))

Test suite

nock('/')

.get('/foo')

.reply(200, {data: "hello"})

This is failing as I'm not giving the proper hostname for the

nock

. Am I doing something wrong?

Found a workaround for this. Have a _ajax-setup.js in your test folder

import $ from 'jquery'

$(document).ajaxSend((event, jqxhr, settings) => {
  settings.url = 'http://0.0.0.0' + settings.url;
})

The thing to note is that this file has to run First and Only Once. Having it as a file runs only once and _ before it makes it alphabetically first.

Later you can test your code with

nock('http://0.0.0.0')
.get('/foo')
.reply(200, {data: "hello"})
