Running tests fails on OS X

[TinyExplosions]

I cloned the gitevents repo, performed an npm install . and then ran npm run test

I get the following errors: (npm is version 3.8.3 and node version is 5.4.0). node is being run via nvm.

$ npm run test

> gitevents@0.4.0 test ~/OSS/gitevents
> npm run test-int

> gitevents@0.4.0 test-int ~/OSS/gitevents
> NODE_ENV=test tape tests/integration/*.js | tap-spec

milestone = arguments.varValue;

This is as much for your info as a bug report, as I suspect it could be my setup that's causing the problems! (I'm running OS X 10.11.4, MacBook Pro (Retina, 13-inch, Late 2013))

Running on node v5.9.1 and on ubuntu Wily x64 server happens the same.

The problem isn't your setup, the issue is the integration test is using rewire defining a settter for an internal const defined in lib/event.js:L9(https://github.com/gitevents/core/blob/b9ca06753308ae0a67c8583b25c1014215ff7128/lib/events.js#L9)

An V8 runtime because protect const vars reassignation

Not sure why the test passed in the CI and in other dev machines, as I haven't been involved in the development for long time.

I expect that somebody involved recently in the development will provide better explanation and will fix it shortly.

Sorry for the inconveniences and many thanks for reporting it.

[ifraixedes]

Removing 3 lines of test/integration/event.js L9:L12 should the issue.

I'm not sending a PR because I haven't got pass a few expects of test/integration/talks.js which may be because I miss to setup something.

[PatrickHeneise]

there shouldn't be any setup required for the tests. Please submit the PR and I'll continue to investigate as well.
