In Nock, URL seems ok to me but is not matched - node.js

Question

I am trying to use nock to intercept a call from my app to the internet.
The goal here is to avoid using a variable external API when testing.
What I do is :
describe('My awesome test', () => {
beforeEach(() => {
let scope = nock('http://www.myexternalapi.eu')
.log(console.log)
.post('/my/awesome/path')
.query(true)
.reply(200, response);
console.error('active mocks: %j', scope.activeMocks())
});
it('Should try to call my API but return always the same stuff ', () =>{
myService.doStuffWithAHttpRequest('value', (success) => {
// The answer must always be the same !
console.log(success);
});
})
// Other tests...
}
and myService.doStuffWithAHttpRequest('value', (success) is something like that :
const body = "mybodyvalues";
const options = {
hostname: 'myexternalapi.eu',
path: '/my/awesome/path',
method: 'POST',
headers: {
'Content-Type': 'application/xml'
}
};
const request = http.request(options, (response) => {
let body = "";
response.setEncoding('utf8');
response.on('data', data => {
body += data;
});
response.on('end', () => {
parser.parseString(body, (error, result) => {
// Do a lot of cool stuff
onSuccess(aVarFromAllTheCoolStuff);
});
});
});
When runing my tests, nock display this :
active mocks: ["POST http://www.myexternalapi.eu:80/my/awesome/path/"]
Seems good ! But my request is not matched and the external API is always called !
I have tried :
beforeEach(() => {
let scope = nock('http://www.myexternalapi.eu/my/awesome/path')
.log(console.log)
.post('/')
.query(true)
.reply(200, response);
console.error('active mocks: %j', scope.activeMocks())
});
It don't work neither.
beforeEach(() => {
let scope = nock('myexternalapi.eu')
.log(console.log)
.post('/my/awesome/path')
.query(true)
.reply(200, response);
console.error('active mocks: %j', scope.activeMocks())
});
It don't work neither and display a weird URL :
active mocks: ["POST null//null:443myexternalapi.eu:80/my/awesome/path/"]
Plus something is weird :
Nock can log matches if you pass in a log function like this:
.log(console.log)
Do not display anything... ?! Any idea ?
Thanks you, I'm going crazy with this...

Answer 1

The values you're providing to nock and post are not quite right.
Try this.
let scope = nock('http://www.myexternalapi.eu')
.log(console.log)
.post('/my/awesome/path')
.reply(200, response);
The string argument passed to nock must be the origin, host and protocol, and must not include any path or search param/query info.
Likewise, the post method should receive the path of the call.
One helpful tool when trying to determine why Nock isn't matching a request is to debug which Nock has integrated. So however you're running your tests, prepend DEBUG=nock*.
