Selenium WebDriver findElement(By.xpath()) not working for me

Question

I\'ve been through the xpath tutorials and checked many other posts, hence I\'m not sure what I\'m missing. I\'m simply trying to find the following element by xpath:

Answer 1

element = findElement(By.xpath("//*[@test-id='test-username']");
element = findElement(By.xpath("//input[@test-id='test-username']");

(*) - any tagname
