Selenium code for Video click in iFrame works in Debug but fails in normal,tried sleep,wait etc

The code below works as expected in debug mode of Eclipse, but when try Normal mode, I get the error below. I even increased thread.sleep from 3000 to 12000 but still fails at Normal mode.
In debug mode, when I put a breakpoint at line 45 and 46 and step over them, the Video plays.

Rather than using sleep to wait for the element, try using an explicit WebDriverWait and ExpectedConditions to repeatedly poll the DOM for your desired state.
I've updated your example below:
/**
* Unit test for simple App.
*/
public class AppTest extends TestCase
{
public static void main(String[] args) throws InterruptedException {
System.setProperty("webdriver.chrome.driver", "C://Sprints//chromedriver_win32//chromedriver.exe");
//System.setProperty("webdriver.gecko.driver", "C://Sprints//geckodriver-v0.19.0-win64//geckodriver.exe");
WebDriver driver = new ChromeDriver();
// WebDriver driver = new FirefoxDriver();
driver.manage().timeouts().implicitlyWait(5, TimeUnit.SECONDS);
driver.get("http://utubehits.com/");
//This is the magic thing. It will repoll the dom for 25 seconds before it gives up.
WebDriverWait explicitWait = new WebDriverWait(driver, 25);
explicitWait.until(ExpectedConditions.visibilityOfElementLocated(By.name("login"))).sendKeys("wealthytarundas2015#gmail.com");
explicitWait.until(ExpectedConditions.visibilityOfElementLocated(By.name("pass"))).sendKeys("Tapan#321");
explicitWait.until(ExpectedConditions.elementToBeClickable(By.name("connect"))).click();
explicitWait.until(ExpectedConditions.elementToBeClickable(By.linkText("YouTube Views"))).click();
explicitWait.until(ExpectedConditions.elementToBeClickable(By.linkText("Watch Video"))).click();
System.out.println(driver.getTitle());
//driver.switchTo().parentFrame();
List<WebElement> frameElements = explicitWait.until(ExpectedConditions.visibilityOfAllElementsLocatedBy(By.cssSelector("iframe[id='iframe']")));
//--------- HERE I PUT BREAK POINT ----------
System.out.println(frameElements.size());
//........ HERE I PUT BREAK POINT ----------
//I'm not certain I have this exactly right, you may have to fiddle with it a bit
explicitWait.until(ExpectedConditions.frameToBeAvailableAndSwitchToIt(By.cssSelector("iframe[id='ytPlayer']")));
Thread.sleep(3000);
explicitWait.until(ExpectedConditions.elementToBeClickable(By.cssSelector("button[class='ytp-large-play-button ytp-button']"))).click();
}
}
Using explicit waits in combination with setting the implicit waits can help to account for many timing conditions various browsers experience during testing.
Best of Luck.

Webdriver Expected condition failed: waiting for element to no longer be visiblr

I have a method which waits for a css (Modal) locator to not be visible on screen, on some of my builds I get the following failed message
Expected condition failed: waiting for element to no longer be

My method:

return this.wait.until(ExpectedConditions.invisibilityOfElementLocated(By.cssSelector(".modal-body")));
}

Loading web elements in your page will be different each time you run your code so you should increase the wait time in your web driver wait and try running your code more than once to be sure your driver have waited enough time for the element to be loaded
try below :
WebDriverWait wait = new WebDriverWait(driver, 40);
wait.until(ExpectedConditions.invisibilityOfElementLocated(By.cssSelector(".modal-body")));

There is nothing wrong in this method and you use it right.
The code of this method (on C#) is:
return (Func<IWebDriver, bool>) (driver =>
{
try
{
return !driver.FindElement(locator).Displayed;
}
catch (NoSuchElementException ex)
{
return true;
}
catch (StaleElementReferenceException ex)
{
return true;
}
});
So probably your element was visible indeed. Try to increase your timeout and maybe to make screenshots on failure to be able to view real data and to know if the element is visible or not indeed.

org.openqa.selenium.NoSuchElementException - Selenium Test

I am assumming that you are trying to click a "link" named "Finding Dory" on this page:
But this is not a link - try to click it manually, it simply is not possible to click on it.
If you click on it, nothing happens, it's just not clickeable - this is nothing but a simple text "Finding Dory".
What you can do is to click a link named "Play trailer" that is located below the text "Finding Dory". The problem is that there are many links with the same name "Play trailer" on this page, and WebDriver doesn't know which link should be clicked, and returns an error if you try a simple method findElement( By.linkText('Play trailer')).click();
You need to tell WebDriver that it should click on the link that is located under the text "Finding Dory". To do it you need more advanced locating strategies than a simle method By.linkText. The two the most popular are locating using xpath or css expressions.
First you need to examine a structure of this page. Open this page in the browser, and press F12 key - this opens Developer Tools window (how to use this tool is beyond this answer). You will see something like this:
That is:
DIV tag that contains a text "Finding Dory"
followed by A tag that contains a text "Play trailer"
You can build an xpath expression for the above, that finds a link "Play trailer" located under a DIV tag that contains "Finding Dory" in this way :
//div[contains(.,'Finding Dory')]/following-sibling::a[contains(.,'Play trailer')]
and then replace this line of your code:
driver.findElement(By.linkText("Finding Dory")).click();
with this one:
driver.findElement(
By.xpath(
"//div[contains(.,'Finding Dory')]/following-sibling::a[contains(.,'Play trailer')]"
)).click();

You can try the following code
driver.findElement(By.xpath(.//a[contains(text(),'Finding Dory'))].click();
Note: If "Finding Dory" is having any link then only the above code will work.

Scrolling Webelement using Selenium Webdriver with Java

Please help me to handle StaleElementReferanceException.
I am trying to scroll a webelement using action class.
Below is the code:
public void newsSearch() throws StaleElementReferenceException{
driver.get("https://pi.persistent.co.in");
driver.manage().timeouts().implicitlyWait(30, TimeUnit.SECONDS);
driver.findElement(By.id("ui-accordion-1-header-2")).click();
Actions act = new Actions(driver);
int numOfPixels = 2;
WebElement draggablePartOfScrollbar = driver.findElement(By.xpath("//*[#id='ui-accordion-1-panel-2']/div/div[2]/div[2]/div"));
for (int i = 2; i < 50; i = i + numOfPixels) {
act.moveToElement(draggablePartOfScrollbar).clickAndHold().moveByOffset(0, numOfPixels).release().perform();
System.out.println("Inside for loop");
}
System.out.println("After for loop");
driver.findElement(By.xpath("//*[#id='ulNotification']/li[5]/h3")).click();
driver.close();
}
It is giving an Exception:

I tried using try catch, still it is not working.
Thank you in advance.

In for loop condition at number of iteration you are getting exception?
Because once the element is moved or dragged, page DOM will update and that element will not longer available to move again. That's the reason your are getting StaleElementReferenceException. See this explanation about StaleElementReferenceException
And your code to move element should be like below:
act.moveToElement(draggablePartOfScrollbar).clickAndHold().moveByOffset(0, numOfPixels).release().build().perform();

This is because of the following two reasons from here:
A stale element reference exception is thrown in one of two cases, the
first being more common than the second:
The element has been deleted entirely. The element is no longer
attached to the DOM.
Generally this happens in ajax based sites. One way is to solve this is to refetch the element, because of ajax call the DOM would have been changed.
