Unable to require node-hid in Travis CI

When requiring node-hid in Travis-CI I get this error “cannot initialize hidapi (hid_init failed)”.

I am unable to run unit tests on modules that use node-hid on Travis-CI because this error is thrown when node-hid is required. I have tried to stub out the module in my tests without any luck. I have traced this to https://github.com/node-hid/node-hid/blob/master/src/HID.cc#L583. This code is being run when the module is required and I think this should be done when the HID instance is created.

const HID = require('node-hid'); // Is thrown her.

const device = new HID.HID(path); // Should be thrown her.

I believe this has been fixed in the latest release. We’re currently doing builds in Travis too. Thanks for your patience.

Thanks, that does work.

Only because mockery is so overly aggressive when it does it’s mocking.

You can get node-hid to install on travice by adding this to travis.yml.

before_install:
  - sudo apt-get update
  - sudo apt-get install build-essential git -y
  - sudo apt-get install libudev-dev -y
  - sudo apt-get install libusb-1.0-0-dev -y
  - sudo apt-get install gcc-4.8 g++-4.8 -y
  - if [[ `npm -v` != 3* ]]; then npm i -g npm@3; fi

I still think that node-hid should not start executing this code when the module is required.
