Continuous Integration and WebDriver !!Urgent!!
Rodrigue
I'm trying to run my automated tests (work fine in my eclipse ide) on
hudson, which is installed on a debian lenny headless server.
To be able to run the automated tests for the UI, I installed Xvfb.
The FirefoxWebDriver points now on a bash script containing the
following command:
xvfb-run -s "-screen 1 1280x1024x24" /usr/local/bin/firefox $1 $2 $3
$4 $5
The command (a wrapper in reality) makes it easy to start a new Xvfb
server for each application you need to run, which lets you run
multiple tests at a time without the applications conflicting with
each other.
I can run the script from the terminal without a problem. Firefox is
started (I recongnize it because the console doesn't return until I
pressed CTRL+C).
Therefore the FirefoxDriver implementation does have problem with it.
The following exception is namely thrown:
org.openqa.selenium.firefox.NotConnectedException: Unable to connect
to host [0:0:0:0:0:0:0:1%1] on port 7055 after 45000 ms

org.openqa.selenium.firefox.FirefoxDriver.<init>(FirefoxDriver.java:

I would like to know if someone out there got automated Ui Test to
work on Xvfb ( a virtual frame buffer X server)
Many many thanks for any help.
Cheers

need to modify FirefoxWebDriver
to point to command that starts Xvfb.
Instead, in my case, i have a script that runs my test and contains
the following:
1. export DISPLAY=":n" --> where n = any integer
2. start Xvfb on screen n
3. run your test
When running test headless from ssh, the display needs to be
specified, then you can start Xvfb and tests will be able to run on
the display
you specified.
hope this helps.

don't you stop the Xvfb server after all your tests are finished?
Thanks

keep your scripts the same. You do not need to modify FirefoxWebDriver
to point to command that starts Xvfb.
Instead,
export DISPLAY=":n" --> where n = any integer
start Xvfb on screen n
run your test
When running test headless from ssh, the display needs to be
specified, then you can start Xvfb and it will run it on the display
you specified.
hope this helps.

Do you start Xvfb the same way you specified above?
When I start my Xvfb I do not specify the browser at all.
Also, are you on Selenium 2.0a5? I am finding some issues with 2.0a5
that are working fine on 2.0a4. I need to investigate further before I
post the issue.

I started in this case as a standalone programm on the server
Pass the Display using an instance of FirefoxBinary
here is the code:
FirefoxBinary firefoxBinary = new FirefoxBinary();
firefoxBinary.setEnvironmentProperty("DISPLAY",
":1");
ProfilesIni allProfiles = new ProfilesIni();
FirefoxProfile profile =
allProfiles.getProfile("default");
DRIVERS.put(WEBDRIVERS_FIREFOX, new
FirefoxDriver(firefoxBinary, profile));
And finally pass the path to firefox by specifying the system variable "
webdriver.firefox.bin"
Yes I'm on selenium 2.0a5? if necessary I could go back to the previous
version.
Many Thanks for all

I got a connection using x11vnc on the server just to see what is going on
there. I could see that during the 45 seconds, the firefox browser was
started, but the webdriver didn't set the url to load.
I think the real problem is that here:
[Exception... "Component returned failure code: 0x80570016
(NS_ERROR_XPC_GS_RETURNED_FAILURE) [nsIJSCID.getService]" nsresult:
"0x80570016 (NS_ERROR_XPC_GS_RETURNED_FAILURE)" location: "JS frame ::
chrome://browser/content/utilityOverlay.js :: getShellService :: line 326"
data: no] "
And seems to be independent from webdriver...
I don't know if some people out there already got and solved such a problem
on firefox...
Many Thanks for your help

Hudson has a very easy to setup plugin called Xvnc, which does it all for you.
That's what I've been using and it's working great so far.

" Rodrigue, are you using the xvnc plugin?"
no I don't, is it a hudson plugin?
Many Thanks
Felipe Knorr Kuhn
It's available at the plugin setup page (Manage Hudson -> Manage Plugins).
After installing it, you'll have an option in your project to enable Xvnc.

Do you know if it also work with the Xvfb server. I cannot find something
about it on the plugin page... I'm asking it, because the vncserver cannot
be find from the sources configured on my debian lenny server...
Many thanks..
Rodrigue Lagoue Njinthe
I installed the xvnc plugin, hudson says it starts vnc server, but the
problem still persists...
perhaps it's a problem with firefox installation. What would be strange,
since I can surf on internet with it...
Many thanks
Rodrigue Lagoue Njinthe
I did it like you mentioned before. My display variable is ":1" but the xvnc plugin start the server at :10
Here is what is printed at start of the hudson job
------------

I also connected to this display from my client using a vnc client. I can see that firefox get started (Probably from Webdriver), but Webdriver somehow doesn't set the url to the application like it should. The Firefox stays open 45s (the time out) and then get killed.
After all I receive an email with the following error:
-----------

Seems like it's a firefox issue. Does anybody already solved such a problem?
Many thanks?

webdriver? I'm telling it because, when I starts the vncserver as daemon,
start firefox and connect on it via the tightvncclient, I can work with
firefox without a problem...
Thanks for your help

" My display variable is ":1" but the xvnc plugin start the server at :10"
I'd suggest that your DISPLAY (in capitals) value should be ":10"

If you launch your tests from Hudson and the xvnc plugin, you don't
need to set the display variable before launching firefox, all
processes spawned by hudson will be redirected to the new display
managed by xvnc.
Since you said you could connect to :10 and see Firefox opening, I
really don't know what else could be wrong.
After searching the group, this seems to be a frequent issue:
https://groups.google.com/group/webdriver/search?group=webdriver&q=7055&qt_g=Search+this+group
I would think that the Firefox extensions are not being installed
properly, but I have no idea how to solve this. Have you tried setting
different profiles?

thanks for your replies. I found it nice... I also think I should check the configuration of firefox on my server...
Rodrigue Lagoue Njinthe
I have just found a workaround with the help of someone who had practically a similar problem.
Why it didn't work?
It seems like the firefox installed on my debian (lenny) headless server doesn't convert from "localhost" to "127.0.0.1" automatically.
The firefox process starts and listen to the address "127.0.0.1:7055" (seen in the output of netstat command), whereas the FirefoxDriver instance tries to make a connection to it using "localhost:7055". The following code from the class FirefoxDriver confirms it:
@Override
protected void startClient() {
LazyCommandExecutor exe = (LazyCommandExecutor) getCommandExecutor();
FirefoxProfile profileToUse = getProfile(exe.profile);
profileToUse.addWebDriverExtensionIfNeeded(false);
// TODO(simon): Make this not sinfully ugly
ExtensionConnection connection = connectTo(exe.binary, profileToUse, "127.0.0.1");
exe.setConnection(connection);
try {
connection.start();
} catch (IOException e) {
throw new WebDriverException("An error occurred while connecting to Firefox", e);
}
}
The solution:
To fix it I just extended the class FirefoxDriver and overrided the #connectTo() method. Since the #startClient() Method uses private classes in it. Here is the code:
--
/**
*
* @author rodrigue
*
*/
public class BaoFirefoxDriver extends FirefoxDriver {
private static final String Localhost = "localhost";
private static final String LocalhostIp = "127.0.0.1";
public BaoFirefoxDriver() {
super();
}
public BaoFirefoxDriver(Capabilities capabilities) {
super(capabilities);
}
public BaoFirefoxDriver(FirefoxBinary binary, FirefoxProfile profile) {
super(binary, profile);
}
public BaoFirefoxDriver(FirefoxProfile profile) {
super(profile);
}
@Override
protected ExtensionConnection connectTo(FirefoxBinary binary,
FirefoxProfile profile, String host) {
String hostToUse = host;
if (Localhost.equalsIgnoreCase(host)) {
hostToUse = LocalhostIp;
}
return super.connectTo(binary, profile, hostToUse);
}
}
------
@Simon
It would be nice to give us a change to change the localhost value more easily.
Thanks again for your help

127.0.0.1 localhost
in your /etc/hosts file?
Rodrigue Lagoue Njinthe
Hi Thómas,
no I don't (I just checked it)
Bartosz Majsak
I was struggling with similar problem today. I'm using Hudson slave to
make headless builds and xvnc plugin to run firefox and webdriver
tests in it.
I was using selenium 2.0a5 version and having similar exception as
mentioned in this thread (ubuntu 10.04 x64, firefox 3.6.8).
When I rolled back to the 2.0a4 version everything is working fine. I
also tried approach with overriding connectTo but it does not work as
well.
So maybe there is some a small issue with firefox driver in alpha5?
Best regards,
Bartosz
