In spite of the many choices for web developers today, ASP.NET Web Forms is alive and well. One of the platform’s many strengths is its long history of stability. Microsoft has kept it current with frequent updates and the .NET Framework 4.7.1 continues to add features that can be utilized by Web Forms applications.
So what does that mean to you? If you are getting ready to build an ASP.NET Web Forms application, what should you consider?
My colleague, Ed Charbeneau, shares his thoughts and recommendations in the “Planning a Modern Web Forms Application” whitepaper. In this post, we’ll look at two excerpts from that paper – Using Controllers and Routing in Web Forms and Testing Methodologies. He explores the ability to take advantage of web API controller architecture without switching to ASP.NET MVC and he shares his thoughts on testing methodologies.
Developers don't need to switch to ASP.NET MVC to take advantage of web API controller architecture in their application. Adding Web API controllers to Web Forms allows the application to leverage simple, but powerful JSON based REST endpoints. Web API endpoints provide a low friction way of supplying data for consumption by AJAX calls from the client side of the application. In addition, these endpoints allow Web Forms to share data with external applications such as reporting services, mobile applications and more.
Web API controllers can be added to a Web Forms application and any point in the application's development cycle. New projects can include Web API as part of the File > New > Project template experience, while existing applications only need to add a WebApiConfig.
By default, Web API will be configured to emit XML from controller actions. To enable JSON formatting simply remove the XmlFormatter from configuration.
// Remove the XML formatter
To add Web API to existing applications, simply add configuration class WebApiConfig to enable Web API routing. The configuration below allows enables both attribute based routing and convention based routing.
How you test and what you test is less important than the fact that you test something. It’s likely the case that you’ll want to test each module or unit of code by writing unit tests. When all of the units of code unite to form a running application, you’ll want to do functional end-to-end testing. Below I detail the tools required:
Microsoft’s standard unit testing library
A free, open-source, community-focused unit testing tool for the .NET Framework
One of the most popular unit testing frameworks for .NET
To take testing to the next level, consider complete a test automation solution for integration testing at the GUI level. One such way to integration test your GUI is with Progress Test Studio.
