A/B testing

A/B testing of Umbraco pages is supported using Escc.Umbraco.ContentExperiments and Google Analytics Experiments.

Each controller that needs to support Google Analytics experiments should create an instance of ContentExperimentSettingsService, and usually pass it to BaseViewModelBuilder.PopulateBaseViewModel(). This checks for an experiment configured in Umbraco, and then sets the ContentExperimentPageSettings property of the model.

public new async Task<ActionResult> Index(RenderModel model)
{
	var viewModel = new MyCustomModel();

	var templateRequest = new EastSussexGovUKTemplateRequest(Request);
	var modelBuilder = new BaseViewModelBuilder(templateRequest);
	await modelBuilder.PopulateBaseViewModel(viewModel, model.Content, 
			new ContentExperimentSettingsService(),  
			null,
            UmbracoContext.Current.InPreviewMode);

    return CurrentTemplate(viewModel);
}  

This project has layout views (UmbracoDesktop.cshtml and UmbracoFullScreen.cshtml) and which inherit from the sitewide layout views provided by the Escc.EastSussexGovUK project, and add support for rendering the Google Analytics Experiments code using the _ContentExperiment.cshtml partial view. So long as the inherited layout views are configured in web.config the code is added to the page in the right place.
