javascript - How can I write integration tests for chrome extension? -


i have written chrome extension loads in developer window. communicates loaded webpage , stores desired data in database.

i want write automated unit test extension in node using selenium, phantomjs/chromedriver, mocha , chai. have written simple test using selenium, chromedriver, mocha , chai. failing right now. have attached error below.

this how looks: client.js

exports.client = require('/usr/local/lib/node_modules/webdriverjs').remote({     // settings     // use webdriverjs create selenium client     desiredcapabilities: {         browsername: 'chrome',         chromeoptions: {             binary: '/applications/google chrome.app/contents/macos/google chrome',             args: [],             extensions: ['/users/divyanshu/downloads/stm_updated_20160308051700.crx']         }     },     loglevel: 'silent' });

test.js

var client = require('./client').client; var expect = require('chai').expect;  describe('test stackoverflow.com', function(){     before(function(done) {         client.init().url('chrome-extension://bfedbpidmfabedhnemcibiciahnjdnid/index.html', done);     });      describe('check homepage', function(){         it('should see correct title', function(done) {             client.gettitle(function(err, title){                 expect(title).to.have.string(                     'stm'                 );                 done();             });         });          it('should see body', function(done) {             client.gettext('#header', function(err, span){                 expect(span).to.have.string(                     'browser'                 );                 done();             })         });     });      after(function(done) {         client.end();         done();     }); });

this how running selenium server: java -jar ~/downloads/selenium-server-standalone-2.53.0.jar -dwebdriver.chrome.driver=node_modules/chromedriver/bin/chromedriver

and how running test: mocha test.js -t 10000

but not able load extension , getting these error: error output of test run:

error output in selenium server: exception: unknown error: cannot process extension #1

i used fs.readfilesync('/users/divyanshu/downloads/stm_updated_20160308051700.crx', 'base64') encode crx file overcome error , got error:

exception: unknown error: cannot parse capability: chromeoptions

i tried load extension without crx file. added in 'args' in 'chromeoptions':

args: ['load-extension=/users/divyanshu/downloads/stm_updated_20160308051700']

this helped me in resolving error: cannot process extension #1

but have stumbled upon new error. not able load html file (index.html). saying "your file not found. may have been moved or deleted. err_file_not_found. reload". how can on come error?

this how manifest.json file looks:

{     "name": "extension",     "description": "tool.",     "icons": {         "16":  "icons/icon16.png",         "48":  "icons/icon48.png",         "128": "icons/icon128.png"     },     "version": "1.1.2",     "manifest_version": 2,     "permissions": [         "webrequest",         "<all_urls>",         "history",         "background",         "storage",         "cookies",         "clipboardwrite",         "tabs"     ],     "options_page": "options.html",     "background": {         "scripts": [             "background-script.js",             "panes/js/jquery.js"         ]     },     "content_security_policy": "script-src 'self' 'unsafe-eval'; object-src 'self'",     "devtools_page": "devtools.html",     "web_accessible_resources": [         "panes/*"     ] }

and devtools.js file load html file have specified location of devtools.html:

var panelwindow, injectedpanel = false, injectedpage = false,     panelvisible = false, savedstack = [];  chrome.devtools.panels.create("extension", "panes/img/logo.jpg",     "panes/index.html", function(panel) {});

so, extension has multiple html files. , want write unit tests those, moving past each file 1 one, like, first have log extension (this login.html), select client (this selectclient.html) etc etc.

index.html loads first can see devtools.js, processing starts , loads other html files 1 one.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
