Hi,
I have been surfing around attempting to look for an answer of how I
can do FileUpload on a Remote Node. I have found numerous suggestions;
using a Webdriver backed Selenium (http://code.google.com/p/selenium/
source/detail?r=10610), using a FileDetector and the (http://
groups.google.com/group/webdriver/browse_thread/thread/
2fb93423c8eae233) BUT I have not found a single full example for my
set up and am struggling to get it to work.

I have the following setup:

1) Images are in Maven test/resources and are available on the
classpath for the server running the unit tests
2) Hudson executes my mvn test target and the hub is available on the
same server as hudson.
3) A remote node running firefox is used to execute the job (I do get
logs like shown below on the node)

Logs on node
22:42:02.374 INFO [14] org.openqa.selenium.remote.server.DriverServlet
- Executing: [send keys: 5
org.openqa.selenium.support.events.EventFiringWebDriver
$EventFiringWebElement@a6919592, [/tmp/1327357083300/

upload5349320589334893179file/banner.jpg"]}"

4) The tests work fine locally and I also attempted to download them
using http in the test code but they images I am trying to upload
never makes it out to the node and stays on the hub.

I know there are a lot of file upload questions out there but it would
be great to hear if someone could point me to the "right" or even a
working solution.

Thanks in advance.

Andreas,

Here's a working example that could help you get started :

public static void showUploadDemo(URL remoteWebDriverURL, DesiredCapabilities dc){

RemoteWebDriver.setLogLevel(Level.INFO);

RemoteWebDriver rwd = new RemoteWebDriver(remoteWebDriverURL,dc);

rwd.get("http://cgi-lib.berkeley.edu/ex/fup.html");

LocalFileDetector detector = new LocalFileDetector();

File file = detector.getLocalFile("C:/Users/krmahadevan/testfile.txt");

rwd.setFileDetector(detector);

rwd.findElementByName("upfile").sendKeys(file.getAbsolutePath());

rwd.findElementByName("note").sendKeys("Test note");

rwd.findElementByXPath("//input[@value='Press']").click();

System.out.println("Page Title ==> " + rwd.getTitle());

System.out.println("Page source contents :\n " + rwd.getPageSource());

rwd.quit();

}

The output :

Hi Krishnan,

I am facing the same problem to upload a file in gmail and found your solution. Can you please explain how to define the "URL remoteWebDriverURL, DesiredCapabilities dc" and how we can pass the firefox driver in below method. I am unable to pass the parameters in the method when calling it in the main method. Thanks in advance.

Hi Krishnan,

I have setup the remote web driver as it is described in the links, but it is again giving me the exception "Error forwarding the new session Empty pool of VM for setup {platform=ANY, javascriptEnabled=true, browserName=firefox, version=}

Command duration or timeout: 607 milliseconds"..

Here is my main method code:

public static void main(String[] args) throws MalformedURLException {

DesiredCapabilities capability = DesiredCapabilities.firefox();

WebDriver driver = new RemoteWebDriver(new URL("http://localhost:4444/wd/hub"), capability);

String remoteWebDriverURL = null;

showUploadDemo(remoteWebDriverURL, capability);

}

Please correct me if i am doing anything wrong.

Thanks,

Neeraj

I have gone through the blog again and i have a little confusion about grid-startup-batch.bat , how we can create this file and in the above link google chrome driver are not available. There is one more thing which i am facing in java if i use this code

DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setBrowserName(DesiredCapabilities.internetExplorer());
URL url = new URL("http://localhost:4444/grid/register");
RemoteWebDriver driver = new RemoteWebDriver(url, capabilities);

then it display a error message on 2nd line. How we can remove this error message.

Use any editor to create a batch file on windows. What is the confusion in that ?

I think you should be using:

capabilities.setCapability...

and not

capabilities.setBrowser name.

The latter will accept a string, not a "capability" type object.

Neeraj,

That was indeed an error in my post.

It should have been :

capabilities.setBrowserName(DesiredCapabilities.internetExplorer().getBrowserName());

Thanks for bringing it up. I have rectified it in my blog

Is it necessary to create a batch file, i mean we can also start the selenium server by using this command in command line "java -jar selenium-server-standalone-2.14.0.jar -role hub", I am new in testing to so idea about syntax of batch file.

Its totally upto you. Batch file is merely as a means for convenience.

Even running the command on the command prompt is also fine.

Used the command line server start and now i am getting this exception.

Exception in thread "main" org.openqa.selenium.WebDriverException: <html>

The main method code is like this now.

public static void main(String[] args) throws MalformedURLException {

DesiredCapabilities capabilities = new DesiredCapabilities();

capabilities.setBrowserName(DesiredCapabilities.firefox().getBrowserName());

URL url = new URL("http://localhost:4444/grid/register");

And if i change the URL to http://localhost:4444/wd/hub this then it display another exception.

Error forwarding the new session Empty pool of VM for setup {browserName=firefox}

What is the meaning of these two URLs?

Neeraj,

Lets go over what we have so far :

1. To work with the Grid, you WOULD need to start both the Grid and the node. If you just have a Grid and NO node, then you are likely to see the error

Error forwarding the new session Empty pool of VM for setup

2. The URL "http://localhost:4444/grid/register" is used by the node to register itself to the Grid. You shouldnt be using that in your test. If you use, you will see those errors

So I would suggest that you please go back and start everything from the scratch.

If you are not comfortable with batch files, then run the commands to start the grid in one command window, open up another command window and run the command to start the node in it.

Then run your test, with the URL referring to "http://localhost:4444/wd/hub"

Thanks & Regards
Krishnan Mahadevan

Thanks Sure, all things gone messy so i have to start again on this problem,

Can you please give me a brief idea about this remotewebdriver, i mean to say, how this remote web driver is able to upload a file but the simple web driver not, can you please provide any good link of remote webdriver and webdriver differences.

All flavors of WebDrivers WILL HELP with File upload.

The way in which you do file upload differs between RemoteWebDriver and all of the rest of the flavors of WebDrivers.

RemoteWebDriver is used ONLY when you are involving a grid. A grid is used when you want to abstract the execution environment from the

local machine i.e., if you have the luxury of having a bunch of machines at your disposal and want to use those machines for running your tests

so that you can use your local machine for your browsing needs, you would opt for Grid.

This is my naive explanation !

Thanks & Regards

I have also tried to use this code but the files is not uploaded,

RemoteWebElement element = (RemoteWebElement) driver.findElement(By.xpath("//div[2]/div/div/div/div/div/div/form/table/tbody/tr[6]/td[2]/span[1]"));

String filePathToUse = new File("C:\\Users\\Neeraj\\Desktop\\Leh").getAbsolutePath();

element.setFileDetector( new LocalFileDetector() );

System.out.println(filePathToUse);

element.sendKeys(filePathToUse);

it is returning me the absolute xpath but the file is not attaching,

This works for me :

public static void main(String[] args) throws MalformedURLException, InterruptedException {

URL url = new URL("http://localhost:4444/wd/hub");

DesiredCapabilities dc = new DesiredCapabilities();

dc.setBrowserName(DesiredCapabilities.firefox().getBrowserName());

RemoteWebDriver driver = new RemoteWebDriver(url, dc);

driver.get("http://cgi-lib.berkeley.edu/ex/fup.html");

RemoteWebElement element = (RemoteWebElement)driver.findElement(By.name("upfile"));

File f = new File("C:/Users/krmahadevan/Desktop/text.txt");

element.setFileDetector(new LocalFileDetector());

element.sendKeys(f.getAbsolutePath());

WebElement ele = driver.findElement(By.xpath("//input[@value='Press']"));

ele.click();

System.out.println("Page URL after upload = " + driver.getCurrentUrl());

System.out.println(driver.getPageSource());

driver.quit();

}

Hi Krishnan,

can you please explain the use of

element.setFileDetector(new LocalFileDetector());

Does this mean we are telling the script to look into a Local file system?What exactly is it's use and what others we may supply as an argument to setFileDetector() function?

Thanks&Regards

That should help you understand more than what I can possibly explain :)

Hi Krishnan ji,

I have updated the batch file with the help of my friend and now the below code is running till entering the absolute path in the text box, after that it is not able to press the button. There are some confusions in my mind:-

1. In the batch file you have used the google chrome driver but in the program you are using the firefox and internet explorer driver. Is this is the main reason of the below code is not running properly.

2. I have also tried this solution to my current problem (To upload a file in gmail compose box) but file is not uploading and it send the email without the attachment. What is the main reason now for that problem.

The batch file was to ensure that even automation runs for Google chrome would be supported on the node. That batch file and my standalone demo code has got nothing in common.

2. I have also tried this solution to my current problem (To upload a file in gmail compose box) but file is not uploading and it send the email without the attachment. What is the main reason now for that problem.

Unless you are working for google, I dont think you should be trying to automate anything on google or gmail for that matter.

I would suggest that you try out on your Application under test. If you are just using all of this for learning purposes, then I would suggest that you either create a local web application

and host it on your local tomcat server and then play around with it, or choose a simpler website. Gmail is much more complicated than you think and I am running out of options as suggestions

How is the node connected to Hudson. I mean slave can be started automatically through the Services and also by slave headless start [ by typing java jar -slave.jar XXXXXXXXXX command ] in a command prompt.[https://wiki.jenkins-ci.org/display/JENKINS/Step+by+step+guide+to+set+up+master+and+slave+machines]
Sometimes, files do not get copied to a node from a shared network path.

Please try to connect the node through JNLP command line option and re execute the tests.

Thanks,
Pavan
