How to get the process id of opened browser in java?

[Anto Aravinth]

Is there any way in which I can get the process id of the launched browser? Is that possible?

I’m using Selenium WebDriver. Test cases are running in mac against Safari browsers.

Any reply on this?

Thanks.

you can just use a stack to track all the window handles, and when you know there will be a new handle you can call WebDriver.getWindowHandles(), and use the last group to minus the stack group, you will get the newly created handle, right?

1) wd.toString();

2) System.getProperty("os.name");

3) JavascriptExecutor js = (JavascriptExecutor) wd;

    Object ms=js.executeScript("return navigator.userAgent","");

    String value =ms.toString();

Not sure what you want.

This will get the user agent. I want is process id.

Fine. Let me explain my problem:

Upload is not working in Safari. WebDriver can’t able to click on the upload button and also the trick of sendKeys to upload file also not working either. So we wrote an applescript for it. Now, in parallel mode, we want to know which safari needs the upload button click. In that case, the only solution is to get the process id of that browser and then send to applescript so that it picks the right one! This is what we are trying. 

Any idea will be great!

Anto,

I haven't gotten the time to actually create a working example of what I am suggesting here. 

But on a high level here's what I think should work:

1. Create a method that would leverage Runtime.getRuntime().exec() and run a shell command which will figure out all the set of process ids matching the "Safari" process before the SafariDriver is instantiated.

2. Make a note of the process id.

3. Instantiate the Safari driver and re-run step (1) and find out the new safari browser process.

There are a lot of quirks with this approach, but I hope it lets you get started.

Thanks & Regards

not sure about java , done in .net but same approach can be applied to java

Out of box, selenium does not expose driver process id or Browser hwnd but it is possible. Below is the logic to get hwnd

• When driver is initialized, get the url for hub and extract the port number
• From port number, find the process id which is using this port for listening, ie. PID of driver
• After navigation, from all instances of iexplore find the parent PID matches the pid of driver, i.e browser pid.
• Get the Hwnd of browser pid once browser hwnd is found , you can use win32 api to bring selenium to foreground.

its not possible to post full code here, the full working solution (C#) to bring browser in front is on my blog
