Error connecting to the hook handler. Is the handler running?

[icambridge]

I get the following on travis.

$ node_modules/dredd/bin/dredd
Configuration dredd.yml found, ignoring other arguments.
Starting server with command: app/api_v6/console server:run --docroot=web 127.0.0.1:8081
Waiting 3 seconds for server command to start...
info: Beginning Dredd testing...
Spawning `bin/dredd-hooks-php` hooks handler
Error connecting to the hook handler. Is the handler running?
{ [Error: connect ECONNREFUSED]
  code: 'ECONNREFUSED',
  errno: 'ECONNREFUSED',
  syscall: 'connect' }

I have no idea why, I've ensured that the file is there and executable. So I've ran the script by itself and put it into the background. This just resulted in getting socket errors when the other tests were running.

When you say "running on travis" do you mean your project that is using dredd to test your web service or are you talking about my repository running on travis?

Please post your travis.yml if its your project. I think I can tell what the issue is from that output but I just want to verify.

Edit: Added information

Can you try to run dredd without using the dredd.yml?? Only reason I ask is because on the Dredd website it specifically says

Read the docs where I got the picture here. Maybe @netmilk can comment on your dredd.yml file. Does this work locally? When I run dredd I use the following command since I figured it would be a bad idea to use the dredd.yml.

dredd ./laravel.apib http://localhost:8001 --server "php -S 0.0.0.0:8001 -t public/" --language vendor/bin/dredd-hooks-php --hookfiles tests/dredd/hooks/hookfile.php

[icambridge]

This appears to be an issue with dredd. I added - bin/dredd-hooks-php & to the script: section instead of before script section and dredd now runs.

It fails for another reason, connecting to the app/server

Hey @icambridge, @ddelnano,

dredd.yml is no longer an unstable feature and is widely used. I'll fix the documentation according to reality. :)

Ad your issue, @icambridge: Dredd is waiting 1 second after spawning the hook worker to connect to it. In this case I would suspect something in your hook files is taking longer time than this 1 second. Is it possible? This interval is unfortunately not configurable at this moment. I added it to the requirements for refactoring of worker client in Dredd here: apiaryio/dredd#235

[netmilk]

@icambridge Is you project open-source or would you be willing to share the code of the project with me? I'm super interested to know more how you use hooks and Dredd and to know more how do you organise code in hooks and what roadblocks did you hit while using Dredd. It would be super useful to know more. Please, feel free to reach out to me via twitter @ntmlk, skype netmilk or email adam@apiary.io. Looking forward to hear from you!
