angularjs - Why is Angular $timeout blocking End-To-End tests? -


i've made directive used show notification messages user. show notification wrote this:

$scope.$watch($messaging.isupdated, function() {     $scope.messages = $messaging.getmessages();     if ($scope.messages.length > 0) {         $timeout(function() {             (var = 0; < $scope.messages.length; i++) {                 if (i + 1 < $scope.messages.length) {                     $messaging.removemessage($scope.messages[i]);                 } else {                     $messaging.removemessage($scope.messages[i]);                 }             }         }, 5000);     } });

i'm using $timeout make sure messages stays on screen 5 seconds.

now want write end-to-end test on can sure notification shown. problem when notification shown end-to-end timed out notification message. makes impossible check whether right notification shown. .

this test code:

it('submit update center', function() {     input('center.name').enter('new name');     input('center.department').enter('new department');     input('center.contact').enter('new contact');     input('center.street').enter('new street');     input('center.city').enter('new city');     input('center.country').enter('new country');     element('button#center_button').click();      expect(element('.feedback').count()).tobe(1);     expect(element('.feedback:first').attr('class')).tomatch(/success/);      expect(element('.error.tooltip').count()).tobe(0); });

i’d avoid using javascript settimeout() , hope there’s (angular) solution problem.

bad news, pal. it's known issue in angularjs. there discussion here , "somehow related" issue here.

fortunately, can workaround rolling own $timeout service, calling settimeout , calling $apply hand (this suggestion discussion i've referred). it's simple, although it's ugly. simple example:

app.service('mytimeout', function($rootscope) {   return function(fn, delay) {     return settimeout(function() {       fn();       $rootscope.$apply();     }, delay);   }; });

note 1 not compatible angular $timeout, can extend functionality if need.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
