Service components in `ngMock`

Name	Description
$exceptionHandler	Mock implementation of `$exceptionHandler` that rethrows or logs errors passed to it. See $exceptionHandlerProvider for configuration information.
$log	Mock implementation of `$log` that gathers all logged messages in arrays (one array per logging level). These arrays are exposed as `logs` property of each of the level-specific log function, e.g. for level `error` the array is exposed as `$log.error.logs`.
$interval	Mock implementation of the $interval service.
$animate	Mock implementation of the `$animate` service. Exposes two additional methods for testing animations.
$httpBackend	Fake HTTP backend implementation suitable for unit testing applications that use the $http service.
$timeout	This service is just a simple decorator for $timeout service that adds a "flush" and "verifyNoPendingTasks" methods.
$controller	A decorator for `$controller` with additional `bindings` parameter, useful when testing controllers of directives that use `bindToController`.
$componentController	A service that can be used to create instances of component controllers. Be aware that the controller will be instantiated and attached to the scope as specified in the component definition object. That means that you must always provide a `$scope` object in the `locals` param.
