$evalAsync triggers a digest, and is unsuitable when it is expected that a digest should not occur.
BREAKING CHANGE
Previously, even if invokeApply was set to false, a $rootScope digest would occur during promise
resolution. This is no longer the case, as promises returned from $timeout and $interval will no
longer trigger $evalAsync (which in turn causes a $digest) if `invokeApply` is false.
Workarounds include manually triggering $scope.$apply(), or returning $q.defer().promise from a
promise callback, and resolving or rejecting it when appropriate.
var interval = $interval(function() {
if (someRequirementFulfilled) {
$interval.cancel(interval);
$scope.$apply();
}
}, 100, 0, false);
or:
var interval = $interval(function (idx) {
// make the magic happen
}, 1000, 10, false);
interval.then(function(idx) {
var deferred = $q.defer();
// do the asynchronous magic --- $evalAsync will cause a digest and cause
// bindings to update.
return deferred.promise;
});

The $interval service simplifies creating and testing recurring tasks.
This service does not increment $browser's outstanding request count,
which means that scenario tests and Protractor tests will not timeout
when a site uses a polling function registered by $interval. Provides
a workaround for #2402.
For unit tests, repeated tasks can be controlled using ngMock$interval's
tick(), tickNext(), and tickAll() functions.
