GetWindow handles returns 01 as the count.

Meta -

OS:
Windows 10
Selenium Version:
2.53.1
Browser:
Internet Explore : 2.53.1

Browser Version:
ie 11.1324.15063.0

Expected Behavior -

Im using to open an application using ie. When browser launches the URL. it open ups another two windows.
User should be able to switch to launched window.

Actual Behavior -

driver returns only count as 01 for driver.getWindowhandles().size();
So cannot switch to the window.

As i see application behaviour as below

• Once url launches. Application it self execute a java script as startup();
  using that script application is opening the other windows. This might be a reason as i assume.

Steps to reproduce -

For issues please provide a concise reproducible test case and describe what results you are seeing and what results you expect.

See CONTRIBUTING.md

[PramodSenda]

It is an application which open ups three window handles while launching.

Expectation to return 03 window handles by selenium , but selenium returns window handles count as 01.

Please provide a concise reproducible test case instead of a narrative description.

I assume it could be my case. Please see steps and comparisons below:

Reproducing on:
geckodriver-v0.23.0-win64
Firefox 62.0.3

Not reproducing on:
ChromeDriver 2.42.591088
Chrome 70.0.3538.102

1. Code with issue. If I try to switch to new tab after click() (driver.switchTo()) without Thread.sleep() - it doesn't work:

        driver.get("https://hotline.ua/computer-noutbuki-netbuki/vinga-twizzle-j116-j116-c40464b/prices/#cond_new");
        System.out.println("getWindowHandles size with 1 tab = " + driver.getWindowHandles().size());
        driver.findElement(By.xpath("//div[@data-selector='price-line']//div[@class='cell-7 cell-md']/a[@class='btn-orange btn-cell']")).click();
        System.out.println("getWindowHandles size with 2 tab = " + driver.getWindowHandles().size());
        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
        }
        System.out.println("getWindowHandles size with 2 tab after Thread.sleep = " + driver.getWindowHandles().size());

2. Console output:

getWindowHandles size with 1 tab = 1
getWindowHandles size with 2 tab = 1

getWindowHandles size with 2 tab after Thread.sleep = 2

3. Same code(issue is not reproducing even in Firefox), but without click() function, simply open new tab using Javascript "window.open(url, '_blank'):

        driver.get("https://hotline.ua/computer-noutbuki-netbuki/vinga-twizzle-j116-j116-c40464b/prices/#cond_new");
        System.out.println("getWindowHandles size with 1 tab = " + driver.getWindowHandles().size());
        ((JavascriptExecutor) driver).executeScript("window.open('https://www.itbox.ua/product/Noutbuk_Vinga_Twizzle_J116_J116-C40464B-p487019/?utm_source=Hotline&utm_medium=PriceList_cpc&utm_campaign=noutbuki&utm_content=U0314607&utm_term=Vinga_Twizzle_J116','_blank');");
        System.out.println("getWindowHandles size with 2 tab = " + driver.getWindowHandles().size());
        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
        }
        System.out.println("getWindowHandles size with 2 tab after Thread.sleep = " + driver.getWindowHandles().size());

4. Console output:

getWindowHandles size with 1 tab = 1

@mlesyk And what's the issue? How many windows did you expect to obtain in this sample?

[mlesyk]

@barancev I expect 2 windows in first sample right after click on link with target="_blank" attribute:
driver.findElement(By.xpath(...)).click();
But for some reason I have to use Thread.sleep(); to wait until getWindowHandles is updated.

[barancev]

Yes, click does not wait for a new window to open, and window opening is not instant. Everything works as expected.

[mlesyk]

But why is the difference between Chrome and Firefox?
Thus Firefox does not wait for a new window to open when use click. But Chrome works as I expected - getWindowHandles is updating immediately, without Thread.sleep need.

[barancev]

Because Chrome is faster to open new windows?

[mlesyk]

@barancev yes, maybe :)
Sorry, I've already read javadoc of WebElement.click() and found peculiarities for it's behavior.
But difference in Firefox and Chrome confused me, thus I thought it could be a bug and wrote here.
