ASP NET Web Examples in C# and VB

To get started, you’ll need to install the Testcontainers NuGet package in a new Unit Test Project. You’ll also need Docker for Desktop installed and running in your development environment. Remember, Testcontainers works with images and manages containers through Docker. Testcontainers is an open-source framework that allows developers to leverage the Docker API to create dependencies through the languages they know and love.

The inversion of control (IoC) and dependency injection (DI) architectural patterns help you enhance the modularity, testability, and maintainability of your application. IoC is a design pattern that enables you to decouple components, substitute dependency implementations, and facilitate testing. DI is a subset of the IoC principle and serves as one method of implementing IoC. In addition to DI, there are several alternative techniques to implement IoC such as events, delegates, template patterns, factory methods, and service locators.

And, as always, thanks for reading and being a part of the JetBrains community. XUnit allows you to create “collections”, a logically-grouped set of tests that share resources. In the scope of this post, we want to share our container across our collection. A decade ago, it was challenging, if not impossible, to automate the creation of application dependencies such as database servers and others with code. Luckily for most modern developers, the idea of containerization has become mainstream. To register services using the TinyIoC container in ASP.NET Core, you should write the following piece of code in the Program.s file of the project we created earlier.

It offers a range of tools, libraries, and features to streamline the development process. ASP.NET Core is a new version of ASP.NET that runs on every major computing platform, including Windows, MacOS and Linux. Like ASP.NET, it is open source, created by Microsoft and allows developers to create web applications, web services, and dynamic content-driven websites. First released in 2016, ASP.NET Core is relatively new, but has already received a 2.0 release and is now a stable alternative to Windows-hosted ASP.NET web applications. Developers who know ASP.NET can leverage their existing knowledge of C# and can quickly pick up the framework differences introduced in ASP.NET Core.

Resolve dependencies in ASP.NET Core

You’ll notice the code is almost identical to the code in the previous sample. Now, let’s modify our test class to use the IClassFixture interface. With xUnit, the IAsyncLifetime methods allow us to start and stop the container.

So a question comes to mind that which technology we were using before the year 2002 for developing web applications and services? The compilation process also provides validation that all of the code is consistent. Interpreted languages would not identify this error until the code is actually run and tested. In a large application, it is very time consuming to manually test what is asp.net every scenario, or to write and maintain additional code that tests of every scenario, whenever code is changed. If you’re new to Testcontainers or unit testing in general, We’d love to hear your questions below. If you’re a longtime user, We’d also love to read about your strategies for increasing confidence in your tests while keeping execution of test suites fast.

How to use TinyIoC in ASP.NET Core

ASP.NET is a widely used framework developed by Microsoft for building web applications, services, and dynamic websites. It is a part of the larger .NET ecosystem and provides developers with a platform to create robust, scalable, and secure web applications. ASP.NET enables developers to build web applications using various programming languages, including C#, Visual Basic, and F#.

With first-class support for Java, Go, Node.Js, Python, Rust, Haskell, Ruby, Clojure, and of course, .NET. Testcontainers turn traditionally heavy-weight and burdensome dependencies into lightweight and throwaway ones. Using Testcontainers allows developers to test against the dependency without fear of incorrect behavior assumptions and limited mocks. With containerization, developers can use technologies like Docker to create instances of databases, message brokers, cache services, and just about anything that runs within a container.

There are also some other technology like Java, PHP, Perl, Ruby on Rails, etc. which can be used to develop web applications. The web applications which are developed using the .NET framework or its subsets required to execute under the Microsoft Internet Information Services(IIS) on the server side. The work of IIS is to provide the web application’s generated HTML code result to the client browser which initiates the request as shown in the below diagram. While not a complete set of all Testcontainer features, We’ve outlined some common approaches for your unit tests.

ASP.NET is written using Object Oriented Programming languages such as C# or VB.net. Object Oriented Programming provides a framework and patterns for code organization and reuse. What type of database to use is an important decision when developing a web application. ASP.NET applications can use all of the popular databases, including Microsoft SQL Server, MySQL, MariaDB, Postgres, MongoDB and CouchDB. While Microsoft SQL Server can require expensive software licenses for complex deployments, the free Express version is suitable for the vast majority of websites. ASP.NET Core is the most common programming model used by .NET developers today, and testing it has never been easier.

Remember, developers are testing on top of complex systems, and the behaviors of those systems can change subtly over time. Working with the “real” dependency allows us to catch these issues early in the development lifecycle. For the sake of simplicity, we’ve created a minimalistic implementation of the TinyIoC container in ASP.NET Core. You can explore the unit tests provided here to learn more about how you can leverage the TinyIoC container.

• DI is a subset of the IoC principle and serves as one method of implementing IoC.
• We’ll use xUnit as my testing framework for the following examples, but these samples will also work in NUnit.
• The complete source code of the Program.cs file is given below for your reference.
• By the end of this post, you should understand the Testcontainers library, some strategies around dependency isolation, and how easy it can be to test existing ASP.NET Core applications.

However, for an open website with anonymous users (that you don’t know), it’s probably best to purchase one that is already in most major browsers, certificate stores. The caveat is that purchasing one, depending on the company, means that it’s already stored in the certificate store for most browsers. Your self published one will not be and your users will have to take the extra step of installing your cert.

ASP.NET Web API

At Embarc, a leading builder of web presences for biotech companies, Matt rose from developer to Director of Technology and board member. He went on to build and run EditMe.com, winner of PC Magazine Editor’s Choice for wiki services, which was acquired by Wakefly in 2011. At Wakefly, Matt upholds a process-driven standard of excellence to deliver exceptional quality and value. Finally, even though ASP.NET is open source and free to use, it is actively developed and supported by the world’s largest software company, Microsoft.
