Does anybody see this issue? It happens on IE9, not sure about other
browsers.
(WebDriver 2.16.0 Java)
Whenever I open an URL, say facbook.com, after a while (maybe 15
seconds), there is always a new browser window pops out,
with URL in address bar:
http://localhost:xxxxx/ (port number changes)
and content of webpage:
This is the initial start page for the WebDriver server.
The main browser window (facebook.com to some other URLs) works fine,
with or without closing the second window.
Thanks,
Lindsay

Hi, Lindsay. I'm a little confused about the sequence of events you're
talking about here. When your WebDriver code starts IE, you get the
(expected) initial page opened up. When and how are you attempting to
open the other URL? In your WebDriver code? When you create your
instance of InternetExplorerDriver, are you just using the default
constructor, or do you mess around with DesiredCapabilities?

WebDriver wd = new InternetExplorerDriver();
something else.....
public File saveScreenShot() {
WebDriver augmentedDriver = new Augmenter().augment(this.wd);
File f = null;
if (augmentedDriver instanceof TakesScreenshot) {
f = ((TakesScreenshot)
augmentedDriver).getScreenshotAs(OutputType.FILE);
} else {
return new File("could-not-take-screenshot");
}
it seems this method creates a new window, and then loses the
reference. augmentedDriver.quit() will only close the main window.

Lindsay,
I do this and it works fine for me since I implemented it. Currently
I am running on 2.14.0, but I have also tried 2.19.0 and I did not see
any such issue. I have posted my code before, but here it is again in
case it helps you. I am using TestNG, so this places the reference to
the image file in the log output, plus each filename is made unique so
I can have multiple screen shots per test suite:

I can confirm this issue. On selenium 2.19, when calling
'Augmenter.augment(driver)' an extra blank browser window is produced
every time. Also, the reference to the new browser is lost and cannot
be closed, as far as I can tell.
If there is a workaround for this, I'd love to see it. Otherwise, I
know this is an experimental class, so I'm not sure if this would be
worth adding as an issue or not.
Thoughts?

Hello Lindsay, I was running into the same issue so I worked around it by casting to RemoteWebDriver rather than using the Augmenter. Since only drivers that support screenshots implement RemoteWebDriver this also gets around the HtmlUnitDriver problem (no screenshot allowed). By the way, this code is implemented inside of a JUnit Rule that I wrote so if any test failure happens it will take a screenshot as long as the driver is compatible. I cleaned out some of my own framework code to simplify it a bit:
File screenshotFile = null;
try {
// This checks to make sure we're not running an
// incompatible driver to take a screenshot (e.g.
// screenshots are not supported by the HtmlUnitDriver)
//the following line will throw a ClassCastException if the current driver is not a browser typed driver
RemoteWebDriver compatibleDriver = (RemoteWebDriver) driver;
screenshotFile = ((TakesScreenshot) compatibleDriver).getScreenshotAs(OutputType.FILE);
} catch (ClassCastException e) {
//this driver does not support screenshots.
// this should get logged as a warning -- this only means the driver cannot be of type RemoteWebDriver
} finally {
if (screenshotFile == null) {
System.out.println("This WebDriver does not support screenshots");
return; //get us outa here
}
}
try {
String pathString = "some path of your choice"
File path = new File(pathString);
if (!path.exists())
path.mkdirs();
stringPath.concat("/someFileName.png");
File newFileLocation = new File(pathString);
System.out.println("Full path to screenshot: " + newFileLocation.getAbsolutePath());
FileUtils.copyFile(screenshotFile, newFileLocation);
} catch (IOException e) {
e.printStackTrace();
}
I hope this helps!

This is the path that we took on this, and so far it looks like its working:
/**
* Helper function to ask the test class to take a picture
*
* @return File pointing to a screenshot
* @throws IOException If file could not be saved
*/
public File takeScreenShot() throws IOException {
WebDriver d;
if (driver.getClass().getName().equals("org.openqa.selenium.remote.RemoteWebDriver")) {
d = new Augmenter().augment(this.driver);
} else {
d = this.driver;
}
File srcFile = ((TakesScreenshot)d).getScreenshotAs(OutputType.FILE);
return srcFile;

I would attribute this behavior to a probable bug in your code. Somewhere in your test code you are creating an additional instance of WebDriver which is what is triggering the duplicate browser window.
