Testing ECONNREFUSED

[redben]

When using nock one can test server http errors.
Is there any way to test request errors like ENOTFOUND or ECONNREFUSED using nock ?

You could use .replyWithError(err) to simulate that. You would have to create a mock error object with the .code attribute, etc.

I'm keeping this issue open, since I think nock could provide an easier way to reply with those types of errors.

@pgte like this:

            nock('http://ww.cantconnecttothis.addres/')
                .get('feed')
                .replyWithError({ 
                    code: 'ENOTFOUND',
                    errno: 'ENOTFOUND',
                    syscall: 'getaddrinfo',
                    hostname: 'www.skdhsdk.com'
                });

Doesn't seems to work.

I wrote a project that starts servers for this in Python: http://github.com/kevinburke/hamms

The easiest way is simply to connect to a localhost port where nothing is listening. ETIMEDOUT you can generally use 10.255.255.1 and set a timeout, though I guess nock can just throw errors on its own if you want.

There's a problem with replyWithError: it doesn't support .delay option. I mean that mocked requests with replyWithError reply immediately with an error regardless of the delay value.

afaik this is also not tested: https://github.com/pgte/nock/blob/049799c35f388d7fbf0a614e1f956a8b5eb7f63d/tests/test_intercept.js#L2863

[pgte]

@1999 could you please create a separate issue for this?

[pgte]

@redben what's the status of this?

[pgte]

@filipedeschamps could you please elaborate?

[1999]

@pgte I can also PR this if you think that's unexpected behaviour

[pgte]

@1999 PR is welcome :)

[1999]

@pgte sorry, I've just re-run tests and acknowledged that everything is okay. The problem was in old nock version used in webdriverio.

[pgte]

I'm closing this for lack of feedback. Please reopen if you have more info.

[redben]

Sorry didn't pay attention to notifications.

• For ECONNREFUSED, I ended up disabling nock and passing a url to the unit under test with a port that I know is closed (http://localhost:{closed-port} )
• For ENOTFOUND i set the url to a random hostname.

So basically these two can be tested without nock. Thanks anyway !
