How to use startTabMirroring method of org.openqa.selenium.chromium.Interface HasCasting class

The problem seems to be when running in a headless environment. If you don't have a window for it to render your browser in, it will hang. You can test this by pasting the same command when you ssh into your machine, but instead do ssh -X me@server.com

I found this documentation on what you can do to fix this: http://www.alittlemadness.com/2008/03/05/running-selenium-headless/

It seems that the Advanced Actions API relies on native events, which are disabled in the Linux version of Firefox by default. Therefore, they must be enabled in the WebDriver instance explicitly.

FirefoxProfile profile = new FirefoxProfile();
//explicitly enable native events(this is mandatory on Linux system, since they
//are not enabled by default
profile.setEnableNativeEvents(true);
WebDriver driver = new FirefoxDriver(profile);

Also, in my case I needed to upgrade the WebDriver to version 2.31 since the hover(moveToElement) action did not work properly on 2.30 even with native events explicitly enabled. Tested this with version 2.31 of WebDriver and versions 17 and 19 of Firefox on Linux. For more information you may check this link:

I would also add +1 for HtmlUnit since its functionality is very powerful: if you are needing behaviour 'as though a real browser was scraping and using the page' that's definitely the best option available. HtmlUnit executes (if you want it to) the Javascript in the page.

It currently has full featured support for all the main Javascript libraries and will execute JS code using them. Corresponding with that you can get handles to the Javascript objects in page programmatically within your test.

If however the scope of what you are trying to do is less, more along the lines of reading some of the HTML elements and where you dont much care about Javascript, then using NekoHTML should suffice. Its similar to JDom giving programmatic - rather than XPath - access to the tree. You would probably need to use Apache's HttpClient to retrieve pages.

Selenium with default configuration creates for every session temporary profile and delete this temp files after work.

So if you want to save cookies (remmember "logged in session") you need to go by one of the following ways:

1. Use the same Chrome driver profile created earlier ( Load Chrome Profile using Selenium WebDriver using java )
2. Create external class for save cookies to some file (c# solution here: Keep user logged in - save cookies using web driver )
3. Do binary Serialyzation of cookies if this is possible and deserialyze when needed

The fact that PhantomJS keeps sessions between tests is a known problem in GhostDriver, the Selenium Webdriver implementation in PhantomJS.

I suppose that this problem will be fixed with the PhantomJS 2 release. The bug is already fixed in GhostDriver 1.1.1, but there is no PhantomJS version which includes this GhostDriver version.

There is a page documenting Advanced User Interactions; which has a lot of great examples on how to generate a sequence of actions, you can find it here

// Configure the action
Actions builder = new Actions(driver);

builder.keyDown(Keys.CONTROL)
   .click(someElement)
   .click(someOtherElement)
   .keyUp(Keys.CONTROL);

// Then get the action:
Action selectMultiple = builder.build();

// And execute it:
selectMultiple.perform();   

or

Actions builder = new Actions(driver);

Action dragAndDrop = builder.clickAndHold(someElement)
   .moveToElement(otherElement)
   .release(otherElement)
   .build();

dragAndDrop.perform();

In a word, no. It's not possible using the Selenium WebDriver API. This has been discussed ad nauseam in the issue tracker for the project, and the feature will not be added to the API.

You can control how the Firefox driver chooses the profile. Set the webdriver.firefox.profile property to the name of the profile you want to use. Most folks think this is a bad idea, because you'll inherit all the cookies, cache contents, etc. of the previous uses of the profile, but it's allowed if you really want to do it.

For example:

System.setProperty("webdriver.firefox.profile", "MySeleniumProfile");
WebDriver driver = new FirefoxDriver(...);

UPDATE - From Ranhiru

How I handled it for Java

FirefoxProfile profile = new FirefoxProfile(new File("D:\\Selenium Profile"));                  
WebDriver driver = new FirefoxDriver(profile);

Then I changed settings in Firefox to clear all cookies and cache when exiting. Look here on how to do it.

I had a similar issue couple of days ago. Apparently I was using an old version of selenium-node image. I updated to latest version and the issue was resolved.
