The product my company provides uses tab index to control the order in which a user can tab through components on a form. This is often a pain to test manually when a page has lots of components displayed on it, something which I did when I first started out as a Software Tester. I quickly found a very popular plug-in called “Developer Toolbar” which will no doubt ring a bell with most web developers & testers which allowed me to speed up the manual check by displaying the components which have a tab index set or not. I’ve been using it for a long time now & find it a great time saver whenever I have to check the tab order of a form somewhere.
I’ll quickly demonstrate how easy this is to use in the video below using a very basic example page.
The application I test has a very complex layout with many levels of inheritance for tab index from parent forms. Most pages have 20+ components with this set on them, so you can only imagine how much easier my life is using Developer Toolbar.
