You will need an Atto WYSIWYG editor (e.g. Add a new forum post) for this testing Enter a wide range of content, which includes: Numbered lists Unordered lists Indented lists Tables HTML copied and pasted from somewhere else Bold Italic Underlined Headings anything else you like... View the full Atto Toolbar View the HTML source of the editor Confirm that the resultant HTML source is coloured Confirm that the resultant HTML source is indented as you would expect Note: Things like Body, Italic, Underline will not be indented in the same that a list with a sublist will be indented. Make some changes Switch back to the normal view Confirm that the changes were made in the normal view Carry out other smoke testing
