From Zero To Hero: Integration Testing In ASP. Net Core

Integration Testing In ASP. Net Core

Integration Testing In ASP. Net Core

Integration tests ensure that an app’s features perform properly at a standard that covers the app’s auxiliary technologies, including the networks, root filesystem, and databases. Integration tests are supported by ASP.NET Core using a functional test automation framework, an or web hosting, and a memory-based test server. This post will cover how to write software testing for our program. Additionally, the article will give you a general concept of adding tests

the Startup template contains. Tests project to test our script. It doesn’t use SQL Server, but rather EF Core’s InMemory database provider. So, our unit tests don’t need a real file to work. For each test, it makes a separate database. So, tests are kept separate from one another. Before testing things, we can use the TestDataBuilder class to add some initial test data to the InMemory database. I made the changes shown below to TestDataBuilder.

public class TestDataBuilder
    private readonly SimpleTaskAppDbContext _context;

    public TestDataBuilder(SimpleTaskAppDbContext context)
        _context = context;

    public void Build()
            new Task("Follow the white rabbit", "Follow the white rabbit in order to know the reality."),
            new Task("Clean your room") { State = TaskState.Completed }

What Are The Integration Tests?

Integration tests assess an app’s elements more thoroughly. Individual board procedures and other independent software modules are tested using test scripts. Integration tests verify that the two or even more software components—possibly all the modules necessary to complete a request—work together and deliver the desired output.

These more thorough tests are employed to assess the foundation and overall status of the application, frequently testing the following elements: –

  • Database
  • File system
  • Network appliances
  • Request-response pipeline

Created objects replace implications for the way, sometimes described as imposters or dummy instances, in unit testing.

You’ll understand deeper why integration tests are crucial for assuring code quality by performing basic API calls to more intricate cases concerning several providers or datasets.

Using xUnit & Moq To Test ASP.NET Core Applications

Testing ASP.NET Core applications using the xUnit and Moq technologies is becoming increasingly common. This system gives programmers strong resources for building trustworthy, strong system testing that will assist in guaranteeing a software’s performance in a company context. In addition to offering an introduction to xUnit and Moq, Additionally, it describes how to set up integration tests and offers detailed directions for creating successful integration tests using these two definitions. Finally, to guarantee that your application is tested extensively before being put into production, this article also includes best practices for using xUnit and Moq.

Mocking Data With Entity Framework Core & Moq

Integration testing is a crucial component of the process and can aid in creating more dependable apps. When creating integration tests in ASP.NET Core, two potent technologies that make it simple to fake data are Entity Framework Core and Moq. To help you immediately realize how to include each tool within your applications, this section describes examples of using Entity Framework Core and Moq for mocking data.

For .NET programmers, the Moq spoofing technology makes it simpler to create mock objects. Compared to manually generating fake things from scratch, it allows you to generate mocked things with precise behavior by writing code in C# or VB.NET.

Troubleshooting Integration Tests In ASP.NET Core

Integration testing is essential for the creation of programs. As ASP.NET Basic has increased in popularity, so have the methods and tools for solving functional testing. This tutorial will offer a thorough overview of troubleshooting integration tests in ASP.NET Core, covering everything from required configuration to finding and fixing issues.

Putting together the TaskController and the ViewModel

See below; I’m adding a new controller class called TasksController.Web project:

public class TasksController: SimpleTaskAppControllerBase
    private read-only ITaskAppService _taskAppService;

    public TasksController(ITaskAppService taskAppService)
        _taskAppService = taskAppService;

    public async Task<ActionResult> Index(GetAllTasksInput input)
        var output = await _taskAppService.GetAll(input);
        var model = new IndexViewModel(output. Items);
        return View(model);

Last Words

Integration testing is a key component of every software development cycle, but several developers aren’t fully aware of its capabilities in ASP.NET Core. The advantages of integration testing and how it can be used enhance efficiency levels, cut down on problems and ensure that all elements are interacting properly.

Integration testing aids in the timely identification of issues by developers, enabling them to be fixed prior to application release. Additionally, it makes it possible to thoroughly check that each component is operating as intended and to set it up so that it will deliver accurate results. Functional testing can also assist programmers in identifying multiple regressions that might happen as a result of upgrades or compiler optimizations, providing that programs endure over time.

Overall, integration testing is essential to every successful software development project, as knowing how to use it in ASP.


Which 4 integration testing types are there?

Types of Integration Testing

  • Big Bang Technique.
  • Bottom-Up Approach.
  • Procedure for hybrid analysis.
  • progressive strategy
  • Drivers and Stubs
  • Top-Down Method.

Which integration testing technique is most often used?

The Big Bang method integrates all components at once and then conducts testing. While it is practical for smaller software applications, it makes it challenging to identify flaws in large-scale systems.

What is the primary goal of integration testing?

Evaluating the interfaces between two software modules or units is an integration test. The correctness of the communication is the main concern. Integrity testing seeks to identify issues with how linked units operate. Before performing the testing process, each module is tested independently.
