I’ve been suffering of selenese flu for months, being on a .net project we were using selenium RC. The typical symptoms are flaky, slow tests and sometimes a lot of sleeps in your code to make it work.
Selenium has its age and it struggles to cope with the current web 2.0 asynchronous calls & rich javascript.
Fortunately old good Simon is working hard at Google on webdriver, and in December the official port has been released also for the .net platform.
It works alright, there are some classes missing and you have to put the IE dll on your project as a content so that it gets copied on the bin folder to make it work.
A part from that, it’s faster, more reliable, more fun to write.
It’s time to cure your flu, webdriver is your medication.
