"(node:20862) UnhandledPromiseRejectionWarning: FetchError: network timeout" when API answer exceeds predefined timeout

[terradek]

Environment:
Frisby 2.1.0 (it works fine on 2.0.16), Node: v10.6.0, Ubuntu 18.04,

Test code snippet:
frisby.timeout(400) // or using .setup({request:{timeout: 400}}) .get(baseUrl+'~info').inspectResponse()

Full ERROR log:
(node:20862) UnhandledPromiseRejectionWarning: FetchError: network timeout at: https://dev.com:443/api/v1.1/~info at Timeout.<anonymous> (/home/and/Desktop/api-test/node_modules/node-fetch/lib/index.js:1338:13) at ontimeout (timers.js:427:11) at tryOnTimeout (timers.js:289:5) at listOnTimeout (timers.js:252:5) at Timer.processTimers (timers.js:212:10) (node:20862) UnhandledPromiseRejectionWarning: FetchError: network timeout at: https://dev.com:443/api/v1.1/~info warning.js:18 at Timeout.<anonymous> (/home/and/Desktop/api-test/node_modules/node-fetch/lib/index.js:1338:13) at ontimeout (timers.js:427:11) at tryOnTimeout (timers.js:289:5) at listOnTimeout (timers.js:252:5) at Timer.processTimers (timers.js:212:10)

PS thank you for development this very handy tool.

Please adjust Jasmine timeout in either way.(default: 5[ms])

• set jasmine.DEFAULT_TIMEOUT_INTERVAL.
• set 3rd argument in it().

@H1Gdev Thanks for your answer.
I'm currently don't use Jasmine. I'm new to Frisby and JS, so my code is very simple:

`'use strict'
const frisby = require('frisby');
const Joi = frisby.Joi;
const baseUrl = 'https://dev.com:443/api/v1.1/';
const defaultJoiOptions = { convert: false, presence: "required" }

frisby.timeout(500) //.setup({request:{timeout: 300}})
.get(baseUrl+'~info').inspectResponse()
.inspectJSON()
.expect('jsonTypes', {
meta: Joi.object({
status: Joi.string().valid('ok').error(() => 'status must be: "ok"'),
error: Joi.equal(null)
}).options(defaultJoiOptions),
});`

And I see that timeout value is set as needed but when endpoint answer time exceeds timeout it throws this error.

I understood your runtime environment.

Frisby is test framework based on Promise.
If error is occured, catch myself or Event: 'unhandledRejection' is emitted.

Update your code.

'use strict'
const frisby = require('frisby');
const Joi = frisby.Joi;
const baseUrl = 'https://dev.com:443/api/v1.1/';
const defaultJoiOptions = { convert: false, presence: "required" }

frisby.timeout(500) //.setup({request:{timeout: 300}})
  .get(baseUrl+'~info')
  .inspectResponse()
  .inspectJSON()
  .expect('jsonTypes', {
    meta: Joi.object({
      status: Joi.string().valid('ok').error(() => 'status must be: "ok"'),
      error: Joi.equal(null)
    }).options(defaultJoiOptions),
  })
  .catch(err => { // <- add catch.
    // catch network timeout and Joi error.
    console.log('error', error.message);
  });

Did you solve this issue?

If you return frisby.get(...) in your tests, the test framework automatically attaches .catch handlers and handles the failure cases. That is the recommended approach when using Frisby. If you always return the Promise in your tests, you will never have to do this manually.
