copied!<p>So, after a lot of searching and trial and error, I was presented with @default.kramer's link, which I duely followed! With a little bit of trial and error, again (best way in my opinion), I managed to get the solution I was looking for. Now, whilst you can follow the link (and I would highly suggest doing so), I am going to post the solution to my question as I implemented it. Hopefully this might help someone with a similar problem.</p> <p>So, I now have my configuration setup class like so :</p> <pre><code>public static class DispatchConfiguration { public static void ConfigureStructureMap(IContainer container, IDispatchConfiguration dispatchConfig) { DispatchProcessBatchSize = dispatchConfig.DispatchProcessBatchSize; ServiceIsActive = dispatchConfig.ServiceIsActive; ... } </code></pre> <p>Now, before I was using a settings file to retrieve the configuration out of the app.config file. This was obviously good for ensuring I had flexibility in changing my config settings, but it left me with the problem of not being able to easily test those settings. Say 9/10 tests required the service to be active, but 1 test wanted to test "ServiceIsActive = false;", now I'm in trouble. </p> <p>Now, however, I am able to inject the configuration from the test :</p> <pre><code>[Given(@"Config\.IsServiceActive returns false")] public void GivenConfig_IsServiceActiveReturnsFalse() { var settings = new DispatchSettings { ServiceIsActive = false, DispatchProcessBatchSize = 100, UpdatedBy = "Unit Test" }; DispatchConfiguration.ConfigureStructureMap(ObjectFactory.Container, settings); } </code></pre> <p>And then in the real world I am able to get the settings from app.config :</p> <pre><code>public void Start(String[] args) { var dispatchConfig = this.GetDispatchConfiguration(); DispatchConfiguration.ConfigureStructureMap(ObjectFactory.Container, dispatchConfig); ... } private IDispatchConfiguration GetDispatchConfiguration() { var config = (DispatchSettings)ConfigurationManager.GetSection("DispatchSettings"); return config; } </code></pre> <p>And then the actual config class looks like :</p> <pre><code>[XmlRoot(ElementName = "DispatchSettings", Namespace = "")] public sealed class DispatchSettings : IDispatchConfiguration { public Int32 DispatchProcessBatchSize { get; set; } public Boolean ServiceIsActive { get; set; } ... } </code></pre> <p>For the sake of completeness the interface looks like so :</p> <pre><code>public interface IDispatchConfiguration { Int32 DispatchProcessBatchSize { get; } Boolean ServiceIsActive { get; } ... } </code></pre> <p>And finally, the config file looks like this :</p> <pre><code><?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="DispatchSettings" type="MyNamespace.XmlConfigurator, MyNamespace.Core" /> </configSections> <DispatchSettings type="MyNamespace.DispatchSettings, MyNamespace.Core"> <ServiceIsActive>True</ServiceIsActive> <DispatchProcessBatchSize>100</DispatchProcessBatchSize> </DispatchSettings> </code></pre> <p></p> <p>Now, anyone with a keen eye will spot "MyNamespace.XmlConfigurator". I found this on one of my Google journeys, and the code allows you to deserialize an Xml config into a class of your desire (as shown in this example). So, to ensure you have the complete code to make this technique work, below is the code for the XmlConfigurator. I cannot remember where I came across it, but a big thanks to the person who wrote it!!</p> <pre><code>public sealed class XmlConfigurator : IConfigurationSectionHandler { public XmlConfigurator() { } public object Create(object parent, object configContext, XmlNode section) { XPathNavigator navigator = null; String typeName = null; Type sectionType = null; XmlSerializer xs = null; XmlNodeReader reader = null; try { Object settings = null; if (section == null) { return settings; } navigator = section.CreateNavigator(); typeName = (string)navigator.Evaluate("string(@type)"); sectionType = Type.GetType(typeName); xs = new XmlSerializer(sectionType); reader = new XmlNodeReader(section); settings = xs.Deserialize(reader); return settings; } finally { xs = null; } } } </code></pre> <p>And there you have it! I hope this allows anyone with a similiar issue to resolve it and is clear enough to follow!</p>
