NOTES: Behat tests will not pass until MDL-76853 is done and this branch is rebased over it. Not everything is covered by Behat tests as tag suggestions and tag completion rely on keyboard events that are unreliable when mocked with JavaScript. Testing: Text formatting: Log into Moodle as an administrator Navigate to: Site administration > Plugins > TinyMCE editor Confirm "TinyMCE HTML formatter" is installed and enabled Navigate to anywhere that uses the TinyMCE editor. For example: the description field when you are editing your own user profile. Add text, tables and a mixture of differently formatted content to the WYSIWYG editor From the TinyMCE editor menu select "view > Source code" Confirm the "Source code" modal appears Confirm that the HTML for the content you entered in WYSIWYG mode is "pretty" formatted (indented etc.) and that the code tags are colored. Tag completion and suggestion: While the source code modal is open from the previous test. If it isn't follow the same setup instructions from that test In code view of the editor start to enter a new HTML tag. For example '<di' Confirm as you enter the partial tag a list of matching potential tags appears Select one of the tags with either your mouse or arrow keys and enter. Confirm that the tag is completed by the editor (without the closing > ) Enter the closing '>' and confirm that a mathing closing tag for the one you entered is automatically generated Finish entering your content then click "save" Confirm that your new content is displayed in the WYSIWYG editor From the TinyMCE editor menu select "view > Source code" Confirm the newly entered HTML code has been formatted and contains coloring.
