Carl and Richard talk to Marcel de Vries about CodedUI - the test functionality built into Visual Studio that nobody knows about. CodedUI tests are tests built to automatically operate your UI so that you can test your application top-to-bottom, no short cuts. Marcel talks about how CodedUI tests are actually built using a test recorder and then tweaking the tests to increase coverage. You can build tables of data to use for entry to challenge boundary testing, add additional assertions and validations - it's very clever! If you own Visual Studio 2013, you need to check this out!
