/**
* @ngdoc service
* @name $window
*
* @description
* A reference to the browser's `window` object. While `window`
* is globally available in JavaScript, it causes testability problems, because
* it is a global variable. In angular we always refer to it through the
* `$window` service, so it may be overridden, removed or mocked for testing.
*
* Expressions, like the one defined for the `ngClick` directive in the example
* below, are evaluated with respect to the current scope. Therefore, there is
* no risk of inadvertently coding in a dependency on a global value in such an
* expression.
*
* @example
<example>
<file name="index.html">
<script>
function Ctrl($scope, $window) {
$scope.greeting = 'Hello, World!';
$scope.doGreeting = function(greeting) {
$window.alert(greeting);
};
}
</script>
<div ng-controller="Ctrl">
<input type="text" ng-model="greeting" />
<button ng-click="doGreeting(greeting)">ALERT</button>
</div>
</file>
</file name="protractor.js" type="protractor">
it('should display the greeting in the input box', function() {
element(by.model('greeting')).sendKeys('Hello, E2E Tests');
// If we click the button it will block the test runner
// element(':button').click();
});
</file>
</example>

function $WindowProvider(){
this.$get = valueFn(window);
