10. Question
Tell me how do you work with multiple windows in
Selenium?

11. Answer
Some web applications have many frames or multiple windows. WebDriver
supports moving between named windows using the “switchTo” method:
driver.switchTo().window("windowName");
You can pass a “window handle” to the “switchTo().window()” method. Knowing
this, it’s possible to iterate over every open window like so:
for (String handle : driver.getWindowHandles())
{
driver.switchTo().window(handle);
}

12. Question

13. Answer
1.’table’ tag defines html table.
2.’tbody’ tag defines container for rows and columns.
3.’tr’ defines rows in an html table.

15. Answer
CSS works with simple attributes like ID and Class, XPATH will traverse the DOM
top down to work with nested elements, so CSS is faster
