#1714 WebSocket authentication
I am using HtmlUnit 2.18 as part of an integration test.
When I try to use WebSockets API I am getting the error
"WebSocket" is not defined
According to change history, initial WebSockets support was added in 2.11
see http://htmlunit.sourceforge.net/changes-report.html
What am I missing?
At first: please use the user maining list for this kind of questions.
And regarding your problem: I guess you are simulation IE8 instead of FF or IE11. WebSockets are not supported by IE8.
Indeed, simulating a browser supporting websockets enabled Java Websockets API wiring.
However, I am unexpectedly getting the error
c.g.h.javascript.host.WebSocket - java.util.concurrent.ExecutionException: org.eclipse.jetty.websocket.api.UpgradeException: Didn't switch protocols, expected status <101>, but got <302>
I say unexpectedly because WebSockets connectivity is successfully being tested separately
The problem is the same both with HtmlUnit Selenium WebDriver and plain HtmlUnit.
This works perfectly using Selenium Firefox Driver.
My WebSockets endpoint requires CAS authentication. (so the 302 code above)
I am always successfully authenticating the browser before testing the WebSockets connectivity.
The HtmlUnit page instance is thus already authenticated. It looks like HtmlUnit tries to create a new connection to my websockets endpoint from zero instead of re-using the browser's authenticated channel (like my Firefox test does or any real browser does in a real scenario)
This is now a totally different problem and complex too.
I hope my description helps
Any ideas?
Do you have a public website for testing?
Thanks,
Yes, I do have a public website for testing
http://eliasbalasis.net:8080/connectivity/delivery?destination="your page URL"
This will take you to a CAS login page, which will indirectly return you, after passing the credentials I will secretly give you, to "your page URL"
"your page URL" can now connect to the WebSockets end-point ws://eliasbalasis.net:8080/connectivity/form/ws/web/main
Please choose a way to secretly transfer the credentials and related testing code parts

Sorry for late response.
WebSocket was changed some time back to use the cookies from the WebClient.
Can you test with latest version, and provide your feedback.
You can directly contact me: asashour [at] yahoo
Thanks,
I will try and get back to you the sooner.
Hi,
Unfortunately the problem persists,
Using "org.seleniumhq.selenium" 2.52.0 maven artifacts with HtmlUnit WebDriver I am getting the following exception
It is worth mentionin no errors are produced while running the exact same tests under the exact same conditions using Firefox WebDriver instead.

the null variable if containingPage_
Any ideas?
It finally works, the problem was selenium dependency inconsistency on "htmlunit", overriding to match solved the problem. Using now selenium 2.53.1, webdriver 0.9.7376, htmlunit 2.21, htmlunit-core-js 2.17, org.apache.httpcomponents:httpclient:4.5.2 and a websockets implementation in the classpath.
This can now be closed
Thanks for the feedback.
