I need to run all test methods one at a time automatically. I have separate testing methods written in separate files. Is there a way to run all test methods at a time automatically. Please suggest if there are any.
Continuous tests: http://continuoustests.com/ - a free, automatic test runner that supports both the .NET and Mono platforms. I do not think he has a command line version.
Gallio http://www.gallio.org/ has a command line runner and a GUI runner (Icarus). I use it, but I'm not sure if it will perform automatic or continuous test runs.
NCrunch http://www.ncrunch.net/ is also an automatic test runner that runs in Visual Studio. It used to be free, but now it’s paid.
IF you use NUnit, you can use the NUnit GUI. Another option, which is mostly agnostic, is TestDriven.Net .
