Write down test cases for Notepad to "Save/Save as" a file.

• Click File-Save (should open a window and should ask you the file name and path as well)
• Check for .extension like it should be .txt only
• Check for short-key like (Ctrl+S) and ask for same option as above (should open an window and should ask you the file name and path as well)
• Save as (should open the same window with same file name path)
• If you change that file name and path in that window then it should accept.
• If you dont give any name in it then data should not be saved.
• Should accept all alph-numeric, space and special characters.
