selenium - Error : profile.getTemplateDir is not a function -


i'm trying implement multi-browser test protractor firefox , chrome. test, need change download path. in chrome, works in firefox, solution found involved changing profile of firefox. found way in answers of question set firefox profile protractor .

but when try run multiple instance of navigator alongside of 1 instance of firefox modified profile, error profile.gettemplatedir not function.

here code in protractor configuration file :

var q = require('q'); var firefoxprofile = require("selenium-webdriver/firefox").profile     function getprofiles() {   let deferred = q.defer();    let multicapabilities = [{     browsername: 'chrome'   }]   deferred.resolve(multicapabilities);   let firefoxprofile = new firefoxprofile();   firefoxprofile.setpreference("browser.download.folderlist", 2);   firefoxprofile.setpreference("browser.download.manager.showwhenstarting", false);   firefoxprofile.setpreference("browser.download.dir", '/tmp');     let foxcapabilities = {     browsername: 'firefox',     firefox_profile: firefoxprofile   };   multicapabilities.push(foxcapabilities);    deferred.resolve(multicapabilities);   return deferred.promise; }  exports.config = {   seleniumaddress: "http://localhost:4444/wd/hub",   specs: [     'spec.js'   ],   framework: 'jasmine2',   getmulticapabilities: getprofiles,   jasminenodeopts: {     defaulttimeoutinterval: 30000   }, };

does knows why error triggered , how resolve ?

thanks

so have digged issue debugging code , seems limitation/bug in selenium web-driver

when getmulticapabilities returns multiple browsers, protractor creates fork of process run test

fork process

this forked process sent profile created json

childprocess send

the childprocess can receive json data in form of text , not in form of profile object

child process jsonify

later creategeckodriver function called profile object. code of creategeckodriver expecting profile object

create geckodriver profile

so code needs fixed in selenium webdriver , should check if profile sent encoded or not. code have used needs fixed encode profile. below work once selenium driver patched allow sending encoded profile

var firefox = require('selenium-webdriver/firefox'); var q = require('q'); var firefoxprofile = require("selenium-webdriver/firefox").profile  var makefirefoxprofile = function (preferencemap) {     var deferred = q.defer();     var firefoxprofile = new firefoxprofile();     (var key in preferencemap) {         firefoxprofile.setpreference(key, preferencemap[key]);     }      firefoxprofile.encode().then(function(encodedprofile){         cap =  {             "browsername": "firefox",             marionette: true,             "firefox_profile": encodedprofile,         };          deferred.resolve(cap);     });      return deferred.promise; };  exports.config = {     seleniumaddress: "http://localhost:4444/wd/hub",     specs: [         'spec.js'     ],     framework: 'jasmine',     getmulticapabilities: function () {         return q.all([             {                 browsername: 'chrome'             },              makefirefoxprofile(                 {                     "browser.download.folderlist": 2,                     "browser.download.dir": "/path/to/save/downloads",                     "browser.helperapps.neverask.savetodisk": "application/zip"                 }             )         ]);     },     jasminenodeopts: {         defaulttimeoutinterval: 180000     } };

i have http interceptor built via tutorial https://scotch.io/@kashyapmukkamala/using-http-interceptor-with-angular2 the problem need have dynamic header changes automatically once changes 'mode' in app. service able tell interceptor change header, or have interceptor pull header (which string)from service each request. able throwing away patch method, call http.patch('new header string') set header string. call in service controls 'mode' setting. wondering if there way interceptor pull recent value service each request or if can add method http provider via interceptor? i've tried call service in interceptor each request returns undefined. because creating new instance of service or copying value before service fired , loaded/changed data. i don't want pass header string every http provider call because defeats purpose of having interceptor, id able set once changes or have provider fetch service before makes request. tl;dr : need add autom
