usage.md

Usage - Config file

onPrepare: require('./capabilities.js'),

Usage - Test files

if (browser.inOSX()) {
  // in Mac...
} else if (browser.inWindows()) {
  // in Windows...
} else {
  // likely in Linux...
}

This may fail JSHint (depending on your configuration) due to:

• Use of '=='
• Use of semi-colon after if/for statements

It'd be nice if these were fixed up :)

Help. I tried using this EXACTLY as shown and I get the following error:

ERROR - failed loading configuration file ./protractor.conf.js
/usr/local/bin/node_modules/protractor/lib/configParser.js:183

This is a pretty "early" failure and it is based on the fact that your supplied function uses the "browser" global reference in the very first functional line. My config file is

exports.config = {
  jasmineNodeOpts: {
    isVerbose: true,
    defaultTimeoutInterval: 120000
  },
  allScriptsTimeout: 120000,
  getPageTimeout: 60000,
  seleniumAddress: "http://localhost:4444/wd/hub",
  specs: ["e2e/specs/login-spec.js",
          "e2e/specs/send-to-one-spec.js",
          "e2e/specs/upload-spec.js",
          "e2e/specs/reset-pswd-spec.js"],
  multiCapabilities: [
    //{browserName: "chrome"},
    {browserName: "firefox",
      firefox_binary: "/Applications/Firefox.app/Contents/MacOS/firefox",
      binary_: "/Applications/Firefox.app/Contents/MacOS/firefox"
    }
  ],

  onPrepare: require('./capabilities.js'),
};

Unless you have left something very important out of your description, this is what you said to do and it should work. But it doesn't.

Any thoughts? Thanks...
