Testing with Visual Studio 2010

The last time I am discovering more and more the test features of Visual Studio 2010. In this blog item I discuss or mention some of these features.

It is possible to execute a code analysis after each developer build. You can enable (or disable) this in the properties of the project; see tab Code Analysis. There are several rules you can configure (globalization rules, basic correctness or of course you can customize these)
It is also possible to measure the quality of the code, with Code Metrics. Code metrics gives some overview in maintanability and complexibility. The code metrics can be used to give a progress overview in a refactor proces to the management, simply export this data to Excel. The index for maintability, complexibility, depth, code coupling and lines of code.
With the Test Impact Analysis feature Visual Studio shows you the tests which are affected on the code change. (use the Test Impace Window)
There are several tests; Code UI Test, Load Test and Web Performance test. You can also use profiling for your application. You can select CPU Samples, Instrucmentation and compare the results and find the method or class which is the most expensive.

Load Tests in Visual Studio

With the help of Visual Studio you can setup a Load Test. A little part of the Load Test is a Web Performance Test (prev. Web Test). A requirement for executing the test again and again without having recording it again is that the ids of the web controls are the same, between postbacks AND IIS restarts. If this is NOT the test will fail, you can solve this by making the web control id constant or maybe you can create an Extraction Rule
