angularjs - Unknown provider's error throw when injecting constant -

-

i having issues running karma tests.

i have service works well, in inject constant csrf_token :

'use strict';  angular.module('app').factory("authenticationservice", function($http,    $sanitize, sessionservice, flashservice, csrf_token) {     var sanitizecredentials = function(credentials) {        return {            email: $sanitize(credentials.email),            password: $sanitize(credentials.password),            csrf_token: csrf_token        };    }; ...

but when running grunt test command, karma's error :

error: [$injector:unpr] unknown provider: csrf_tokenprovider <- csrf_token <- authenticationservice

update karma.conf :

// karma configuration // http://karma-runner.github.io/0.10/config/configuration-file.html  module.exports = function(config) {   config.set({     // base path, used resolve files , exclude     basepath: '',      // testing framework use (jasmine/mocha/qunit/...)     frameworks: ['jasmine'],      // list of files / patterns load in browser     files: [       'app/bower_components/angular/angular.js',       'app/bower_components/jquery/dist/jquery.js',       'app/bower_components/angular-mocks/angular-mocks.js',       'app/bower_components/angular-resource/angular-resource.js',       'app/bower_components/angular-cookies/angular-cookies.js',       'app/bower_components/angular-sanitize/angular-sanitize.js',       'app/bower_components/angular-route/angular-route.js',       'app/bower_components/xdomain/dist/0.6/xdomain.js',       'app/bower_components/sass-bootstrap/dist/js/bootstrap.js',       'app/bower_components/angular-bootstrap/ui-bootstrap-tpls.js',       'app/scripts/*.js',       'app/scripts/**/*.js',       'test/mock/**/*.js',       'test/spec/**/*.js'     ],      // list of files / patterns exclude     exclude: [],      // web server port     port: 8080,      // level of logging     // possible values: log_disable || log_error || log_warn || log_info || log_debug     loglevel: config.log_info,       // enable / disable watching file , executing tests whenever file changes     autowatch: false,       browsers: ['chrome'],       // continuous integration mode     // if true, capture browsers, run tests , exit     singlerun: false   }); };

and constant defined in bootstrap.js file instantiate before app starts :

'use strict';  angular.element(document).ready(function(){     var app = angular.module('app');     var $injector = angular.injector(['ng']);     $injector.invoke(function($http, $rootscope) {         $rootscope.$apply(function() {             $http.get("http://something/token").then(function(response) {                 app.constant("csrf_token", response.data.csrf_token);                 angular.bootstrap(document, ['app']);             });         });     }); });

do know solution karma stop thinking constant provider?

it seams document's ready event never thrown in jasmine test , therefore constant not defined in app module. try mock csrf_token constant in module configuration section of test:

javascript

describe('test', function() {    beforeeach(function() {     module('app', function($provide) {       $provide.constant('csrf_token', 'mock_constant'); // <= mock constant     });   });    // tests go here  });

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
