Funny how older versions of browsers such as Opera are never mentioned. IE versions 6-8 seem to be the only "old" browsers that exist. Which of course is because they're still in use. Myopia reigns supreme.
I've often found that IE versions 4-9 will point out errors I've made in my code, as the IE platform is far more strict than browsers such as Firefox, which scramble to protect bad code.
> Accordingly, automating testing in Internet Explorer is much more involved than any other browser.
As someone that tests in 20+ browsers, I spend a lot more time on Firefox versions 1-13 than I do with IE versions 4-9, especially with scripting. Nevermind Google Chrome, which makes testing incremental versions nearly impossible (and no, auto-upgrades are no guarantee).
> Getting automatic cross-browser JavaScript testing working is a complex affair, and bound to involve some amount of trial and error.
Conclusion: test manually. There are no guarantees.
