Feat: Simulate nodejs-level errors ? #365
Description
Hi,
For testing purpose, I wanted to check the behavior of my application when receiving errors ECONNRESET, ENOTFOUND, ECONNREFUSED or EHOSTUNREACH, and the only solution I found (after quite some time of research) was to do the following:
axiosMock.onGet('/api/v1/version').reply(() => {
throw Object.assign(new Error('connect ECONNREFUSED test:1234'), {
errno: os.constants.errno.ECONNREFUSED,
syscall: 'connect',
address: 'test',
port: 1234,
code: 'ECONNREFUSED'
})
});While it seems to be working as expected, it's rather verbose, and would be super useful to have helpers to throw such errors.
I've made a runkit with a few samples of those errors:

Proposal:
Add an optional parameter to networkError, which would be the code of the error to throw. For what I've seen, errors could look like this:
const NET_ERRORS = {
ECONNRESET: {
code: 'ECONNRESET',
message: 'socket hang up',
errno: os.constants.errno.ECONNRESET,
},
ENOTFOUND: {
code: 'ENOTFOUND',
message: 'getaddrinfo ENOTFOUND http://test:1234',
syscall: 'getaddrinfo',
hostname: 'http://test',
errno: os.constants.errno.ENOTFOUND,
},
ECONNREFUSED: {
code: 'ECONNREFUSED',
message: 'connect ECONNREFUSED 1.2.3.4:1234',
errno: os.constants.errno.ECONNREFUSED,
syscall: 'connect',
address: '1.2.3.4',
port: 1234,
},
EHOSTUNREACH: {
code: 'EHOSTUNREACH',
message: 'connect EHOSTUNREACH 1.2.3.4:1234',
errno: os.constants.errno.EHOSTUNREACH,
syscall: 'connect',
address: '1.2.3.4',
port: 1234,
},
};I'm OK to PR
