so i'm using nodejs to access an API ( league of legend api ) from my server, i tested the route that access the api using httpie ( a simple http client) and everything is working without any issue.
when i wanted to write tests for my api using Jest + supertest, and when i tested the route that access the remote LOL api, a always get this error
Response for preflight has invalid HTTP status code 401
of course i never get this error when i'm using the http client or a webbrowser
Test Method
test('exist route should return 200 if summoner exist', done => {
request(app)
.get('/summoners/exist/yaskillin')
.expect('Content-Type', /json/)
.expect(200)
.then(res => {
expect(res.body.exist).toBeTruthy()
done()
})
})
Route Method
private exist(req: Request, res: Response, next: NextFunction) {
let name: string = req.params["name"];
return this.riotService
.getSummonerByName(name)
.then(result => {
console.log(result)
res.json({ exist: true });
})
.catch(err => {
console.log(err.config)
res.json({ exist: false });
});
}

- Are you using an http request library that tries to simulate cross origin restrictions that exist in the browser? A preflight request is used when a client that implements cross origin restrictions and it detects a different origin or certain custom attributes of the http request. There is generally no CORs from server-based code, but it seems like maybe you have a library that is implementing that or you're actually running some code in a browser. – jfriend00 Commented Apr 22, 2018 at 7:33

Reset to default 20SOLVED --
by default, jest is runner in jsdom mode, that mean that jest is runner in a browser like envirement by default,
what need to be done is to configure it to run in server like envirement you need to put that in your jest.config file
