Did you know?
Did you know that we've been shipping unit tests for DXperience since version 2008.1?
If you've bought the source code version of one of our products, go to our folder in Program Files (or Program Files (x86), if you're running a 64-bit operating system). Navigate into the Sources folder, and choose a product, like DevExpress.Web.ASPxGridView. Under that you should see a Tests subfolder holding all the NUnit unit tests for that product.
Some of the older, more established products don't have NUnit tests yet because they used our in-house testing system (which you really don't want to see), but we're working on it. However, in general all the products we've been releasing over the past several months, say, are represented.
Have a look at the tests, run them, file bugs against them if you find something. We're glad of all feedback.
