Unit Testing custom ConfigurationElement & ConfigurationElementCollection

Question

I have created a custom ConfigurationElement and ConfigurationSection to make it easier to set up a host of application parameters at startup. However,

Well, I ended up simply going with what @CodeCaster suggested and using ConfigurationManager anyway (as suggested by his link here).

I've posted a sample test below:

[Test]
public void ShouldProvideFullProductionServiceConnectionRecord()
{
    //NOTE: Open ConfigTests.config in this project to see available ServiceConnection records

    //Arrange
    ExeConfigurationFileMap fileMap = new ExeConfigurationFileMap { ExeConfigFilename = "ConfigTests.config" };
    Configuration config = ConfigurationManager.OpenMappedExeConfiguration(fileMap, ConfigurationUserLevel.None);

    ServiceConnectionSection section = config.GetSection("AutomationPressDataCollectionServiceConnections") as ServiceConnectionSection;

    //Act
    var productionSection = section.Connections.Get("0Q8");

    //Assert
    Assert.AreEqual("0AB0", productionSection.LocationNumber);
    Assert.AreEqual("DEVSERVER", productionSection.HostName);
    Assert.AreEqual(1234, productionSection.Port);
    Assert.AreEqual("DEVELOPMENT", productionSection.Environment);
}

It requires you add a new .Config file and set its output as Content and set to Copy if Newer (it's in a unit test project). But it's better than having no coverage at all.
