Visual Studio 2010 Web Performance Test / Load tests / Coded UI Tests. ANYONE REALLY USE THESE?

I tried both Selenium and Coded UI for integration testing the project I am working on. I wrote a blog article with my impressions.

The bottom line for me is that both Selenium and Coded UI are still far from perfect, but better than manual testing. I am using Selenium right now, though I might revisit CodedUI if a few things would be fixed in a later version.

experience with Selenium and VS Coded UI test for web apps.

Better than manual testing in my eyes, though the tests are at times hard to maintain and often need to be changed manually to make them more robust. Both tools have browser plugins which can generate tests automatically, but this code is generally not very resilient towards changes in the HTML (in case of web apps).

You will be disappointed if you expect an automated test run orders of magnitude faster than a manual tester. I think the aim of the vendors is to get the automated test execute aboit twice as fast as a manual tester (that can feel painfully slow if you have a large set of tests).
