Web Testing for Ie. How Accurate Is Ietester

Web Testing for IE. How accurate is IETester?

I can confirm your experience: IETester sometimes deviates from what the "real" browser shows. I have seen this even with pure CSS constructions in simulated IE7 and IE8.

I have no own experience with them, but MS offer virtual machine packages for the various versions of IE. They migh be worth a shot, I've been planning to give them a test drive for a while. They run their native browsers and are bound to be 100% reliable.

Is IE Collection reliable tool for testing with various versions of Internet Explorer?

IE isn't designed to be installed side-by-side with other versions. Most of these "all-in-one" testing tools use a trick of the Windows loader that lets you override system DLLs with DLLs in a local directory. Then they package up a random subset of Windows DLLs from different operating system versions and different IE versions and drop them into some UI. The fact that they happen to seem to work in this manner is a coincidence and not reliable. There will be errors and other strangeness, and probably crashes if your target operating system is far enough from the IE version (e.g. IE6 on Win7) and your webpage is significantly complex.

So, to be clear, no, don't use these tools because you can't rely on them to give you an accurate result. If you want to know how your page looks in a given IE version, use the IE App Compat VHDs available free from Microsoft here.

IETester Question

I believe IE8 and IE9 don't even have an IE6 emulation mode (only IE7, I thought). But the best way to test for IE6, is to get a virtual machine up and running with IE6 installed. You could use IETester or one of the various stand-alone versions of IE6 to test it on your development PC (most things will work as expected, after all), and do a final test on the virtual machine.

To my knowledge there are no other tools that emulate every quirk of IE6 better.

Allows you to test several versions of all the major browsers, including MSIE.

ietester? site looks very stretched?

Those multiple side-by-side IE testing programs are not reliable.

You should use the Microsoft App Compat VHDs (which are free).

Does IETester run the ACTUAL same code that existed for IE6 / IE7? Or is it an emulation?

Experience had taught me that MultiIE/IETester et al, are never 100% accurate, when you're running other versions of IE.

I would run the VM versions to be 100% sure.

Alternative to IETester

Unfortunately the options are somewhat limited.

You can use VMWare with a Windows XP (or lower) install to test IE6

You can use VirtualPC (free) with a (free) XP/IE6 image from Microsoft

You used to be able to use Spoon.net to run just the browser via a plugin in Firefox/whatever

You can try MultipleIE's but IE6 will break and not work if IE8 is installed locally

Or if you are really lucky, you can DROP IE6 support!

IE 6 OR IE Tester -

As noted by the IE team many times, tools like IETester are inherently less reliable than testing with the real browsers, because the approach they use is an unsupported hack, and leads to crashes and cases where the "real" IE binaries get munged with the older ones you're trying to test. You should test IE6 using the free VPC that Microsoft provides.

You could use an extension for your favourite browser, i.e. LinkChecker for Firefox.
