Single click in selenium acts as double click

问题

I have a simple code where I click on a link and it opens up a new window. But while executing the script, single click acts as double click on the same element and 2 windows are opened.

I am using InternetExplorer driver

String baseURL = "URL_to_opened";

DesiredCapabilities cap = DesiredCapabilities.internetExplorer();

cap.setCapability(InternetExplorerDriver.NATIVE_EVENTS, false);

cap.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS,true);

 WebDriver driver = new InternetExplorerDriver(cap);

driver.get(baseURL);

driver.findElement(By.xpath("Element to be clicked")).click();

When you work with Selenium 3.4.0, IEDriverServer 3.4.0 with IE(v 10/11), you may consider passing the following configuration properties through DesiredCapabilities Class:

Native Events: As the InternetExplorerDriver is Windows-only, it attempts to use so-called "native", or OS-level events to perform mouse and keyboard operations in the browser. This is in contrast to using simulated JavaScript events for the same operations. The advantage of using native events is that it does not rely on the JavaScript sandbox, and it ensures proper JavaScript event propagation within the browser. However, there are currently some issues with mouse events when the IE browser window does not have focus, and when attempting to hover over elements.

Browser Focus:The challenge is that IE itself appears to not fully respect the Windows messages we send the IE browser window (WM_MOUSEDOWN and WM_MOUSEUP) if the window doesn't have the focus. Specifically, the element being clicked on will receive a focus window around it, but the click will not be processed by the element. Arguably, we shouldn't be sending messages at all; rather, we should be using the SendInput() API, but that API explicitly requires the window to have the focus.

You can find more documentation about these facts in this link.

Sample Code Block:

DesiredCapabilities cap = DesiredCapabilities.internetExplorer();
cap.setCapability(InternetExplorerDriver.NATIVE_EVENTS, true);
cap.setCapability(InternetExplorerDriver.REQUIREWINDOWFOCUS, true);
cap.setCapability(InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS,true);
WebDriver driver = new InternetExplorerDriver(cap);
