How to click on Cancel on a windows explorer that displays when a upload button is clicked on a web page using Selenium WebDriver with Java

I am very new to Selenium WebDriver with Java. There is a Upload button on a job portal. When I click on that button windows explorer is displayed to choose the file. there are open and cancel buttons on this window. i want to select the cancel button. since it is a windows explorer i cannot inspect the cancel button. how do we write the code for cancelling the button. Thanks in advance.
driver.get("https://my.indeed.com/resume?from=gnav-homepage&co=US&hl=en_US");
driver.manage().window().maximize();
Thread.sleep(3000);
driver.findElement(
By.xpath("//[#id='container']/div/div/div[2]/div/div/div[2]/div/div[1]/div/div[1]/button")).click();

I do not have Java programming skills. I hope the below python code is easy to translate. In my opinion, combining windows action with selenium calls is often flaky.
There is a hidden element called 'upload resume button', you can change the attribute value to see it on the UI, use the send keys method on the element to upload the resume.
from selenium.webdriver import Remote, DesiredCapabilities
driver = Remote(desired_capabilities=DesiredCapabilities.CHROME)
driver.get('https://my.indeed.com/resume?from=gnav-homepage&co=US&hl=en_US')
driver.execute_script(
"document.getElementById('upload-resume-button').setAttribute('class', '')"
)
upload_your_resume = driver.find_element_by_id('upload-resume-button')
upload_your_resume.send_keys(r'C:\test\resume.docx')
The above code worked in my local.

Short answer is you cant, but if you want to upload a local file you can use send_keys on the input field, sending the file path.
Here is a python exemple:
driver.find_element_by_id("IdOfInputTypeFile").send_keys(os.getcwd()+"/image.png")

you can use Robot class to simulate native keyboard and mouse actions to interact with windows based pop-ups.
The shortcut to close any opened window is: “Alt + Space +C” – Closes the focused window.
Robot rb = new Robot();
rb.keyPress(KeyEvent.VK_ALT);
rb.keyPress(KeyEvent.VK_SPACE);
rb.keyPress(KeyEvent.VK_C);
rb.keyRelease(KeyEvent.VK_C);
rb.keyRelease(KeyEvent.VK_SPACE);
rb.keyRelease(KeyEvent.VK_ALT);

unable to read child window element in selenium as parent window getting closed

I am working with selenium automation. I have coded to login a page and it works fine. The login passed and new child window was opened as a result and parent window was closed.
Due to that my web driver stops and result in exceptions.
Exception in thread main org.openqa.selenium.NoSuchWindowException:
No window found (WARNING: The server did not provide any stacktrace information)
Please help

Selenium keeps a list of windows (handles). The webdriver needs to point to the right handle. When a window is closed, its handle is deleted, and your driver will now point to something that doesn't exist anymore.
Likely, you have to explicitly switch window to point your driver to the right window handle. Maybe this could help:
Switch between two browser windows using selenium webdriver
Selenium python bindings: Moving between windows and frames
"new child window was opened as a result and parent window was closed"
The code below from (1) shows you how to retrieve the list of window handles, and retrieve the right handle based on its title.
private void handleMultipleWindows(String windowTitle) {
Set<String> windows = driver.getWindowHandles();
for (String window : windows) {
driver.switchTo().window(window);
if (driver.getTitle().contains(windowTitle)) {
return;
}
}
}
You can use that function (or something similar) to retrieve the new window. From the code you provided, this would give:
// Entering the credentials in the login window.
driver.findElement(By.id(txtUserId)).clear();
driver.findElement(By.id(txtUserId)).sendKeys(poovan);
driver.findElement(By.id(txtPassword)).clear();
driver.findElement(By.id(txtPassword)).sendKeys(welcome1);
driver.findElement(By.id(btnSubmit)).click();
// Here the login window gets closed, handler to that window disappears, and driver becomes stale.
// So we need update the driver to point to the new window
handleMultipleWindows("The title of my new window");
driver.findElement(By.name(bono)).sendKeys(080);

Please use below code. It will work for sure.
String parentWindow = driver.getWindowHandle();
Set<String> handles2 = driver.getWindowHandles();
for (String windowHandle : handles2) {
if (!windowHandle.equals(parentWindow)) {
driver.switchTo().window(windowHandle);
}
}

Selenium code to open facebook messenger and send a message

I'm just starting to learn a little bit of Selenium scripting (in Java). Currently I'm trying to open a chat box in Facebook and send a message.
I have gotten up to being able to open the chat box through selenium, however I can't figure out how to actually type things into the text box.
Currently here is my code:
import org.openqa.selenium.*;
import org.openqa.selenium.chrome.ChromeDriver;
public class practice {
public static void main(String[] args) throws InterruptedException {
System.setProperty("webdriver.chrome.driver", "C:/max/chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http://facebook.com/login/");
driver.manage().window().maximize();
driver.findElement(By.name("email")).sendKeys("myemail#yahoo.com");
driver.findElement(By.name("pass")).sendKeys("myPassword");
driver.findElement(By.id("loginbutton")).click();
driver.findElement(By.name("mercurymessages")).click();
driver.findElement(By.cssSelector("a[href*='https://www.facebook.com/messages/conversation-8148306']")).click();
// This has worked randomly. Sometimes the driver will work and open the chat box. Sometimes it will say element not found. I didn't include the full link of the conversation because apparently you don't have to. And it has worked like this in the past.
}
}
My current issue I'd like resolved is: why does this only work sometimes, and how do i find the text box area on the chat box? I did an Inspect Element and the chat box is very odd. It doesn't have anything like an id or a name, so i can't do By.id, or By.name. I can't figure out how to do it with By.cssSelector. This is what the inspect element for the text box looks like:
textarea class="uiTextareaAutogrow _552m" data-ft=".... more stuff here" onkeydown=" more stuff here" style= "more stuff here."

You have to learn Xpath and how to create Relative xpath.The xpath for the textarea
driver.findElement(By.xpath("//textarea[#class='uiTextareaAutogrow _552m']"));
Anyhow I've made few changes that Include instead of clicking on some other message.It will create a new message and send to your friend
driver.findElement(By.name("mercurymessages")).click();
//wait for 20 seconds
WebDriverWait wait = new WebDriverWait(driver, 20);
wait.until(ExpectedConditions.visibilityOfElementLocated(By.id("u_0_5")));
driver.findElement(By.id("u_0_5")).click();//To click on Send a New Message Link
//To enter a name into the to field
wait.until(ExpectedConditions.visibilityOfElementLocated(By.xpath("//input[#class='inputtext textInput']")));
WebElement friendName = driver.findElement(By.xpath("//input[#class='inputtext textInput']"));
friendName.sendKeys("Deep");//Change it with your friend name
//wait for the user list to appear
wait.until(ExpectedConditions.presenceOfElementLocated(By.xpath("//li[#class='user selected']")));
friendName.sendKeys(Keys.ENTER);
WebElement messageBox = driver.findElement(By.xpath("//textarea[#class='uiTextareaAutogrow _552m']"));
wait.until(ExpectedConditions.visibilityOf(messageBox));
messageBox.sendKeys("Hi there");
messageBox.sendKeys(Keys.ENTER);

Hi pal hope this gonna help you:
there is a method called By.className so in order to find elements without an id or a name you can use this method, the thing it's that sometimes the class name of the element it's used in other elements, so be aware of the uses in the current page, if you are lucky and the class name is unique then you can use it :)
System.setProperty("webdriver.chrome.driver", "C:/max/chromedriver.exe");
WebDriver driver = new ChromeDriver();
driver.get("http://facebook.com/login");
driver.manage().window().maximize();
Thread.sleep(5000);
driver.findElement(By.name("email")).sendKeys("myemail#yahoo.com");
driver.findElement(By.name("pass")).sendKeys("myPassword");
driver.findElement(By.id("loginbutton")).click();
Thread.sleep(5000);
driver.findElement(By.name("mercurymessages")).click();
Thread.sleep(7000);// here you have to use ExpectedConditions in order to verify that the elemnt it´s "clickable"
driver.findElement(By.cssSelector("a[href*='https://www.facebook.com/messages/conversation-8148306']")).click();
Thread.sleep(5000);
WebElement mssgbox = driver.findElement(By.cssSelector("textarea[class*='uiTextareaAutogrow _552m']"));
mssgbox.click();
mssgbox.sendKeys("hi");
hope this help you.
and some times elements in the pages changes so use ExpectedConditions to be sure the element its on the page

How to handle overlay/popup window using selenium webdriver

I am trying to automate initial configuration(of my server) through webpage. After hitting my server ip https:/localhost:4443 and entering my credentials ,i get a window to change password(overlay/popup window).
Problem:- if i browse the same ip from another m/c or from another browser , i get a window over window i.e one more window over change password window(Please click the link to see the screenshot).
What i tried is to get the handle of the window but its not working, its providing one handle only.
**Its not frame also.
HTML code -- https://dl.dropboxusercontent.com/u/91420517/Html_Code.JPG
Here's my code
WebDriver driver=new FirefoxDriver();
driver.get("https://localhost:4443/ControlPoint/");
driver.findElement(By.xpath("//*[#id='name']")).sendKeys("xxxxxx");
driver.findElement(By.xpath("//*[#id='pass']")).sendKeys("xxxxxx");
driver.findElement(By.xpath("//*[#id='loginForm123']/div[6]/div[1]/div")).click();
Set<String> winIds = driver.getWindowHandles();
System.out.println("Total Windows --- " + winIds.size()); // its resulting the size as 1 which is not correct.
Iterator<String> it = winIds.iterator();
String mainWin=it.next();
String changeWin=it.next();
String shareWin =it.next();
driver.switchTo().window(shareWin);
String warning = driver.findElement(By.xpath("html/body/div[4234]/div[1]/span")).getText(); // to get the text on 3 window
System.out.println(warning);
How to resolve this issue .Please help. Any other way to click on buttons on window 3.

If the additional window is opened asynchronously, then possibly you are checking for it (with getWindowHandles()) too early, before it has been created - this is a common issue with Selenium tests and asynchronous page updates.
If this is the issue, it can be solved by trying a few times with a wait in between, checking each time whether a new window has appeared.

Selenium Webdriver screenshots do not show driver errors

I'm creating screenshots in my testcases with selenium webdriver, and while these indeed show what is visible in my web application, it doesn't show popups created by the browser.
I have found that in IE in some cases, my app triggers a JS debug popup in IE. This is of course an error and breaks the rest of my test, but the screenshot does not show the error. I presume this is because it's an IE native popup, rather than one trigger by my application.
Is it possible to get this included in the screenshots? I was thinking of maybe creating the screenshot with Robot#createScreenCapture() but obviously that wouldn't show anything useful if the browser is minimized.
So, a few possible solutions:
- can you detect if an error message pops up in a browser
- is it possible to maximise/focus the browser while running?
- can you take screenshots from selenium with the popups showing?

Selenium will take a screenshot that represents the rendered DOM that the browser shows the end user by intercepting the rendered image that the browser is displaying and taking a copy of it.
It does not take a desktop screenshot so the screenshots shown will not show anything covering the browser window. JavaScript alerts are not part of the rendered DOM so you will not see these in Selenium screenshots.

Maybe because the driver is not with the Alert/Window active?
You could try something like this:
private void CheckForOtherWindows()
{
//Check for any other window open
if (driver.WindowHandles.Count > 0)
{
foreach (string window in driver.WindowHandles)
{
driver.SwitchTo().Window(window);
TakeScreenshot();
}
}
//Check for alert window
try
{
driver.SwitchTo().Alert();
TakeScreenshot();
}
catch
{
//Nothing
}
}
This is not tested, not sure if works. Just giving the idea. :)
Edit:
To maximize the window is easy:
driver.Manage().Window.Maximize();
Hope it helps.

You can use this as below:
FileUtils.copyFile(((TakesScreenshot) driver).getScreenshotAs(OutputType.FILE), new File("E:\\ScreenShot\\screenshot.png"));
