使用ServerManager .net C＃的单元测试方法

Question

How would you test such method that uses ServerManager. Obviously you can't mock ServerManager. And this method is void. Is there a workaround? Should one event test such method? Thanks!

 public void AppPoolRemoval(string poolName)
    {
        using (var serverManager = new ServerManager())
        {
            var oldPool = serverManager.ApplicationPools[poolName];
            if (oldPool != null)
            {
                oldPool.Delete();
                serverManager.CommitChanges();
            }
        }
    }

There's no way to unit test this code in isolation. You'd better write an integration test for it where you would have some IIS instance to test it on.

You could abstract this logic behind an interface:

public interface IWebServer
{
    void AppPoolRemoval(string poolName);
}

and then unit test in isolation the code that depends on this. But the actual implementation which is tied to a real ServerManager cannot be unit tested.
