Using values from AppConfig file in C#
I think a better idea is to write a wrapper class to everything that deals with configuration, especially if you write tests. A simple example might be:
public interface IConfigurationService{ string GetValue(string key);}This approach will allow you to mock your configuration when you need it and reduce complexity
So you could proceed with:
public void SelTest(IConfigurationService config){ var selenium = new DefaultSelenium(config.GetValue("TestMachine"), 4444, config.GetValue("Browser"), config.GetValue("URL"));}or you could inherit your configuration from a List and reduce the typing to:
config["Browser"]
Yes, you can do
ConfigurationManager.AppSettings[""]As it is already a string.
If you're using ConfigurationManager.AppSettings["Something"] at multiple places, you should create a static Config class, that reads your AppSettings via static properties.
You can go to the properties of the project and add Settings, then read it with: Properties.Settings.Default.Property
