Selenium UI Automation for copy clipboard feature

Recently, I came across a UI Automation scenario where I need to validate the clipboard behavior of a field. 

The scenario was: I need to click on a copy SQL button which copies a large SQL which I need to validate. Earlier, I have used the ctrl+c and ctrl+v approach, but here, there was no text field where I can paste that content.

So, at run time, I need to validate the content has been copied or not.  

To automate this, I used the java clipboard class. 

Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard();

Once the clipboard object is created, you can click on the element.

driver.findElement(By.cssSelector("div:nth-child(2) > .input-group .octicon-clippy")).click();

Thread.sleep(2000);

Now, you can extract this data.

Object dataFromCopyURLFeature = clipboard.getData(DataFlavor.stringFlavor);

System.out.println("Copied data is " + dataFromCopyURLFeature);

You can assert this data, with the actual data for validation purpose.

Assert.assertTrue(dataFromCopyURLFeature.equals("https://github.com/qamatters/KarateDemo.git"), "Validate the url");

Let me know if code is needed for this.
