My unit tests add and delete entities from local Windows Azure dev storage, at their most basic. If the Azure Storage emulator isn’t started, the tests don’t fail quickly – they just sit there acting like the test framework is hung. In order to ensure that the tests proceed, I needed to make sure the emulator was started before the tests ran.
I started with code found in this thread on StackOverflow. I needed to make sure the Storage Emulator is started before the test classes are called and that the emulator is shut down when the tests are done. I wrote this class and added it as a separate file to my test assembly.
More information about CSRun.exe and the Process class are available in MSDN.
