Selenium Webdriver and Firefox 18 - firefox

My Selenium tests use onMouseOver features like
List<WebElement> menuitems = getDriver().findElements(By.tagName("li"));
Actions builder = new Actions(getDriver());
WebElement menu = menuitems.get(2);
getDriver().manage().timeouts().implicitlyWait(Constants.IMPLICITY_WAIT, TimeUnit.SECONDS);
builder.moveToElement(menu).build().perform();
I'm using Firefox driver. Since Firefox updated itself to version 18, my tests stopped working. I know this has to do with native events support - but does not version 18 support native events, or am i able to enable them? If not, is there any replacing implementation to my code?
I'm using selenium java 2.28.0.

For Firefox 18 support we need use selenium webdriver api 2.28.0,jar.

Selenium Java 2.27 mentions that native support for FF17 has been added. However, there has been no mention of support for FF18 in the change logs for 2.28. So its webdriver not supporting native events and not FF18 not supporting native events. You can try downgrading to FF 17 and probably turn off automatic updates for some time.

Rolling back to FF17 is a temporary work around until WebDriver version supports FF18
FF17 Extended Support Release packages -- http://www.mozilla.org/en-US/firefox/organizations/all.html
Note: If you are Mac user, you can simply rename your current FF from 'FireFox' to 'FireFox18' in your applications folder. Install the package from the above URL, which should create a new application called 'FireFox' that will be used by WebDriver.

My hover-over broke with v28. I now use the following hoverOver method with an optional javascript workaround and it seems to work okay.
public void HoverOver(IWebElement elem, bool javascriptWorkaround = true)
{
if (javascriptWorkaround)
{
String code = "var fireOnThis = arguments[0];"
+ "var evObj = document.createEvent('MouseEvents');"
+ "evObj.initEvent( 'mouseover', true, true );"
+ "fireOnThis.dispatchEvent(evObj);";
((IJavaScriptExecutor)driver).ExecuteScript(code, elem);
}
else
{
Actions builder = new Actions(driver);
builder.MoveToElement(elem).Build().Perform();
}
}

I was facing the same issue with Firefox 20. Then I re-installed latest Selenium server (.jar files).

Hope this works!

How to configure Safari webdriver to use .pac file

I am working on automation repo with Ruby and Watir framework. I found a ways to set the pac file for chrome and firefox webfrivers.
Examples:
chrome: args << "--proxy-pac-url=#{pac_file_path}"
firefox: profile['network.proxy.autoconfig_url'] = pac_file_path
My question is how can I set it for Safari webdriver ?
Thanks !
Theoretically you should be using a proxy configuration in your capabilities. There was a bug with Selenium Options and Proxy until Selenium 4 beta 4, which was just released.
I encourage everyone to upgrade to Watir 7 and Selenium 4 even though they are still technically in beta, they are more reliable than the latest release of 6.x and 3.x.
With Watir 7.0.0.beta4 and Selenium 4.0.0.beta4 you should be able to do this:
proxy = Selenium::WebDriver::Proxy.new(type: :pac,
proxy_autoconfig_url: pac_file_path)
Watir::Browser.new :safari, options: { proxy: proxy }
Once I merge this PR and release Watir 7.0.0.beta5, then this will work:
Watir::Browser.new :safari, proxy: {type: :pac,
proxy_autoconfig_url: pac_file_path}

Second Instance of firefox browser is not opening in selenium

I am new to selenium. And I am trying to open multiple instances of firefox browser.
I am not using any Grid. And My selenium version is 2.47.1 and firefox version is 37.0.1.
Also, my browser is not closing automatically even I used quit()
Below is my code:
package TestAutomation;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;
public class TestClassOpenBrowser {
public static void main(String[] args) {
WebDriver driver = new FirefoxDriver();
driver.get("http://www.facebook.com");
driver.manage().window().maximize();
WebDriver d2 = new FirefoxDriver();
d2.get("http://yahoo.com");
d2.manage().window().maximize();
driver.quit();
d2.quit();
}
}
Keep in mind that version 2.42.0 was probably the last version of Selenium that really supported Firefox native events (for Firefox 31). Selenium 2.43 says it supports native events for Firefox32 but I don't think it really worked. In general, if you are running local Firefox instances, you want to be using Firefox 31 or Firefox31.0.6 , even if your on Selenium 2.47+ .
Also, if you are having trouble managing multiple driver instances, take a look at how I did it here (see the ShootoutSuiteTestBase.java
class) :
https://gist.github.com/djangofan/f5eda36f556fc55a5dcb
Tried with jar file version 2.45.0. it worked. Issue was in the latest jar files 2.47.1

Best way to control firefox via webdriver

I need to control Firefox browser via webdriver. Note, I'm not trying to control page elements (i.e. find element, click, get text, etc); rather I need access to Firefox's profiler and force gc (i.e. I need firefox's Chrome Authority and sdk). For context, I'm creating a micro benchmark framework, not running a normal webdriver test.
Obviously raw webdriver won't work, so what I've been trying to do is
1) Create a firefox extension/add-on that does what I need: i.e.
var customActions = function() {
console.log('calling customActions.')
// I need to access chrome authority:
var {Cc,Ci,Cu} = require("chrome");
Cc["#mozilla.org/tools/profiler;1"].getService(Ci.nsIProfiler);
Cu.forceGC();
var file = require('sdk/io/file');
// And do some writes:
var textWriter = file.open('a/local/path.txt', 'w');
textWriter.write('sample data');
textWriter.close();
console.log('called customActions.')
};
2) Expose my customActions function to a page:
var mod = require("sdk/page-mod");
var data = require("sdk/self").data;
mod.PageMod({
include: ['*'],
contentScriptFile: data.url("myscript.js"),
onAttach: function(worker) {
worker.port.on('callCustomActions', function() {
customActions();
});
}
});
and in myscript.js:
exportFunction(function() {
self.port.emit('callCustomActions');
}, unsafeWindow, {defineAs: "callCustomActions"});
3) Load the xpi during my webdriver test, and call out to global function callCustomActions
So two questions about this process.
1) This entire process is very roundabout. Is there a better practice for talking to a firefox extension via webdriver?
2) My current solution isn't working well. If I run my extension via cfx run directly (without webdriver) it works as expected. However, neither the sdk nor chrome authority do anything when running via webdriver.
By the way, I know my function is being called because the log line "calling customActions." and "called customActions." both do print.
Maybe there are some firefox preferences that I need to set but haven't?
It may be that you do not need the add-on at all. Mozilla uses Marionette for test automation of Firefox OS amongst other things:
Marionette is an automation driver for Mozilla's Gecko engine. It can
remotely control either the UI or the internal JavaScript of a Gecko
platform, such as Firefox or Firefox OS. It can control both the
chrome (i.e. menus and functions) or the content (the webpage loaded
inside the browsing context), giving a high level of control and
ability to replicate user actions. In addition to performing actions
on the browser, Marionette can also read the properties and attributes
of the DOM.
If this sounds similar to Selenium/WebDriver then you're correct!
Marionette shares much of the same ethos and API as
Selenium/WebDriver, with additional commands to interact with Gecko's
chrome interface. Its goal is to replicate what Selenium does for web
content: to enable the tester to have the ability to send commands to
remotely control a user agent.

Clear Firefox cache in Selenium IDE

I'm using Selenium IDE to test a web application. Sometimes my tests succeed even though they should have failed. The reason is that the browser happens to load a previous version of a page from the cache instead of loading the newer version of that page. In other words, I might introduce a bug to my app without being aware of it because the tests may pass after loading a previous working version instead of loading the new buggy version.
The best solution I could have thought of is to delete the browser cache before running the tests. I have a Selenium script in which I run set-up selenium commands before running the tests. Is there a selenium command to clear Firefox cache? Alternatively, is there another way to prevent loading pages from the cache during the tests?
In python this should disable firefox cache:
profile = webdriver.FirefoxProfile()
profile.set_preference("browser.cache.disk.enable", False)
profile.set_preference("browser.cache.memory.enable", False)
profile.set_preference("browser.cache.offline.enable", False)
profile.set_preference("network.http.use-cache", False)
driver = webdriver.Firefox(profile)
hope this helps someone
You can disable the cache in firefox profile.
See this link for more details.
For those programming in Java, here is how I solve the issue:
FirefoxProfile profile = new FirefoxProfile();
profile.setPreference("browser.cache.disk.enable", false);
profile.setPreference("browser.cache.memory.enable", false);
profile.setPreference("browser.cache.offline.enable", false);
profile.setPreference("network.http.use-cache", false);
FirefoxOptions options = new FirefoxOptions().setProfile(profile);
driver = new FirefoxDriver(options);
Disclaimer: I've never had to do this before (clearing the cookies has always been sufficient for me), but from what I can see, this is functionality that is lacking in the current builds of Selenium, although from recent changelogs, it looks like the developers are making a push to make a standard way of doing this. In 2.33 of iedriverserver, They have the following changenote:
Introduced ability to clean browser cache before launching IE. This version
introduces the ie.ensureCleanSession capability, which will clear the
browser cache, history, and cookies before launching IE. When using this
capability, be aware that this clears the cache for all running instances of
Internet Explorer. Using this capability while attempting to run multiple
instances of the IE driver may cause unexpected behavior. Note this also
will cause a performance drop when launching the browser, as the driver will
wait for the cache clearing process to complete before actually launching
IE
http://selenium.googlecode.com/git/cpp/iedriverserver/CHANGELOG
To do this, you would specify this at driver creation time in the DesiredCapabilities Map using ensureCleanSession.
http://code.google.com/p/selenium/wiki/DesiredCapabilities
Since you're using firefox, it looks like you're out of luck in using a native way to do this. If you haven't tried driver.manage().deleteAllCookies();, I'd try that to see if it gets you where you need to be.
For C# and Geckodriver v0.31.0
public Task<WebDriver> newInstance()
{
return Task.Run(() =>
{
foreach (var process in Process.GetProcessesByName("geckodriver"))
{
process.Kill();
}
FirefoxProfileManager profilemanager = new FirefoxProfileManager();
System.Collections.ObjectModel.ReadOnlyCollection<String> profilesList = profilemanager.ExistingProfiles;
foreach (String profileFound in profilesList)
{
Console.WriteLine(profileFound);
}
FirefoxOptions options = new FirefoxOptions();
FirefoxProfile profile = profilemanager.GetProfile("default");
//profile = webdriver.FirefoxProfile()
profile.SetPreference("browser.cache.disk.enable", false);
profile.SetPreference("browser.cache.memory.enable", false);
profile.SetPreference("browser.cache.offline.enable", false);
profile.SetPreference("network.http.use-cache", false);
WebDriver driver = new FirefoxDriver(options);
return driver;
});
}

How to Stop the page loading in firefox programmatically?

I am running several tests with WebDriver and Firefox.
I'm running into a problem with the following command:
WebDriver.get(www.google.com);
With this command, WebDriver blocks till the onload event is fired. While this can normally takes seconds, it can take hours on websites which never finish loading.
What I'd like to do is stop loading the page after a certain timeout, somehow simulating Firefox's stop button.
I first tried execute the following JS code every time that I tried loading a page:
var loadTimeout=setTimeout(\"window.stop();\", 10000);
Unfortunately this doesn't work, probably because :
Because of the order in which scripts are loaded, the stop() method cannot stop the document in which it is contained from loading 1
UPDATE 1: I tried to use SquidProxy in order to add connect and request timeouts, but the problem persisted.
One weird thing that I found today is that one web site that never stopped loading on my machine (FF3.6 - 4.0 and Mac Os 10.6.7) loaded normally on other browsers and/or computers.
UPDATE 2: The problem apparently can be solved by telling Firefox not to load images. hopefully, everything will work after that...
I wish WebDriver had a better Chrome driver in order to use it. Firefox is disappointing me every day!
UPDATE 3: Selenium 2.9 added a new feature to handle cases where the driver appears to hang. This can be used with FirefoxProfile as follows:
FirefoxProfile firefoxProfile = new ProfilesIni().getProfile("web");
firefoxProfile.setPreference("webdriver.load.strategy", "fast");
I'll post whether this works after I try it.
UPDATE 4: at the end none of the above methods worked. I end up "killing" the threads that are taking to long to finish. I am planing to try Ghostdriver which is a Remote WebDriver that uses PhantomJS as back-end. PhantomJS is a headless WebKit scriptable, so i expect not to have the problems of a real browser such as firefox. For people that are not obligate to use firefox(crawling purposes) i will update with the results
UPDATE 5: Time for an update. Using for 5 months the ghostdriver 1.1 instead FirefoxDriver i can say that i am really happy with his performance and stability. I got some cases where we have not the appropriate behaviour but looks like in general ghostdriver is stable enough. So if you need, like me, a browser for crawling/web scraping purposes i recomend you use ghostdriver instead firefox and xvfb which will give you several headaches...
I was able to get around this doing a few things.
First, set a timeout for the webdriver. E.g.,
WebDriver wd;
... initialize wd ...
wd.manage().timeouts().pageLoadTimeout(5000, TimeUnit.MILLISECONDS);
Second, when doing your get, wrap it around a TimeoutException. (I added a UnhandledAlertException catch there just for good measure.) E.g.,
for (int i = 0; i < 10; i++) {
try {
wd.get(url);
break;
} catch (org.openqa.selenium.TimeoutException te) {
((JavascriptExecutor)wd).executeScript("window.stop();");
} catch (UnhandledAlertException uae) {
Alert alert = wd.switchTo().alert();
alert.accept();
}
}
This basically tries to load the page, but if it times out, it forces the page to stop loading via javascript, then tries to get the page again. It might not help in your case, but it definitely helped in mine, particularly when doing a webdriver's getCurrentUrl() command, which can also take too long, have an alert, and require the page to stop loading before you get the url.
I've run into the same problem, and there's no general solution it seems. There is, however, a bug about it in their bug tracking system which you could 'star' to vote for it.
http://code.google.com/p/selenium/issues/detail?id=687
One of the comments on that bug has a workaround which may work for you - Basically, it creates a separate thread which waits for the required time, and then tries to simulate pressing escape in the browser, but that requires the browser window to be frontmost, which may be a problem.
http://code.google.com/p/selenium/issues/detail?id=687#c4
My solution is to use this class:
WebDriverBackedSelenium;
//When creating a new browser:
WebDriver driver = _initBrowser(); //Just returns firefox WebDriver
WebDriverBackedSelenium backedSelenuium =
new WebDriverBackedSelenium(driver,"about:blank");
//This code has to be put where a TimeOut is detected
//I use ExecutorService and Future<?> Object
void onTimeOut()
{
backedSelenuium.runScript("window.stop();");
}
It was a really tedious issue to solve. However, I am wondering why people are complicating it. I just did the following and the problem got resolved (perhaps got supported recently):
driver= webdriver.Firefox()
driver.set_page_load_timeout(5)
driver.get('somewebpage')
It worked for me using Firefox driver (and Chrome driver as well).
One weird thing that i found today is that one web site that never stop loading on my machine (FF3.6 - 4.0 and Mac Os 10.6.7), is stop loading NORMALy in Chrome in my machine and also in another Mac Os and Windows machines of some colleague of mine!
I think the problem is closely related to Firefox bugs. See this blog post for details. Maybe upgrade of FireFox to the latest version will solve your problem. Anyway I wish to see Selenium update that simulates the "stop" button...
Basically I set the browser timeout lower than my selenium hub, and then catch the error. And then stop the browser from loading, then continue the test.
webdriver.manage().timeouts().pageLoadTimeout(55000);
function handleError(err){
console.log(err.stack);
};
return webdriver.get(url).then(null,handleError).then(function () {
return webdriver.executeScript("return window.stop()");
});
Well , the following concept worked with me on Chrome , try the same:
1) Navigate to "about:blank"
2) get element "body"
3) on the elemënt , just Send Keys Ësc
Just in case someone else might be stuck with the same forever loading annoyance, you can use simple add-ons such as Killspinners for Firefox to do the job effortlessly.
Edit : This solution doesn't work if javascript is the problem. Then you could go for a Greasemonkey script such as :
// ==UserScript==
// #name auto kill
// #namespace default
// #description auto kill
// #include *
// #version 1
// #grant none
// ==/UserScript==
function sleep1() {
window.stop();
setTimeout(sleep1, 1500);
}
setTimeout(sleep1, 5000);
