first line: the letter "a" and then a text input field filled with repeating "foobarbaz", then the word "text" followed by a disabled text input field filled with "foo" and then the letter "b" and then "a"
second line: and then a password input field that's filled and then the word "password" and then a disabled password field that's filled
and then the letter "b"
third line: the letter "a" and then a checkbox (unchecked) with the word "checkbox" and then a disabled checkbox and letter "b"
fourth line: the last line has the letter "a" and then a redio button (unselected) and then the word "radio" and then a disabled radio button and the letter "b"
