Deprecation warnining in Node 7

Expected behavior

Things to work! (i.e. no deprecation warnings crashing Karma)

Actual behavior

This deprecation warning:

node.exe : (node:2636) DeprecationWarning: Using Buffer without `new` will soon stop working. Use `new Buffer()`, or preferably `Buffer.from()`, `Buffer.allocUnsafe()` or `Buffer.alloc()` instead.

Environment Details

• Karma version (output of karma --version): 1.3.0
• Relevant part of your karma.config.js file: N/A (I think - here’s my config)
• OS: Windows only

Steps to reproduce the behavior

1. Run Karma in Node 7
2. Watch the output

This came up in CI, and has been failing my Windows builds (oddly, it’s not affecting my Linux builds). Downgrading Node did fix the problem, though.

Just as a reference the deprecation warning was introduced with https://github.com/nodejs/node/pull/8169/commits/996389c0b9bf87e3b393d06e18e722635035d579 and reverted with https://github.com/nodejs/node/commit/4fffe32a4b3a93548c4d39b1c2531aa38403b5e6. So in the next 7.x node version it should not cause any troubles anymore, but it might be a breaking change in nodejs 8

Here’s the involved files:

• karma.conf.js:

module.exports = function(config) {
  config.set({
    frameworks: ['mocha'],
    files: ['test.js'],
    browsers: ['Chrome'],
    singleRun: true,
  })
}

• package.json:

{
  "scripts": {"test": "karma start"},
  "devDependencies": {
    "karma": "^1.3.0",
    "karma-chrome-launcher": "^2.0.0",
    "karma-mocha": "^1.3.0",
    "mocha": "^3.2.0"
  }
}

• test.js:

describe("foo", function () {
    it("works", function () {})
})
