Useful Cucumber steps help inspect a Capybara session by opening the current page in a browser or starting an interactive debugger.

MySQL 5.x rejects Unicode characters above U+FFFF, so emoji and many historic scripts cannot be stored in UTF-8 columns.

Feature files in nested directories can stop Cucumber from loading env.rb and step definitions unless the features directory is required explicitly.

Adds Photoshop-like rulers and guides to a web page with a JavaScript library; also available as a bookmarklet for quick browser use.

Markup inflates naive length checks in WYSIWYG text. Stripping tags and normalizing non-word characters yields a more accurate character count.
