In the Arrange section, you will perform any required setup for the test scenario. Select the project as shown in the figure 5, Since the Controllers (MVC and API) are constructor injected using IService type, to instantiate the Controller class, we need to mock the IService interface. var cat = await catService.UpdateAsync(id,category); { // Assert the model count Yeah, the duplication was unintentional. var newEmployee = GetTestCategory(); XUnit allows you to test on many different things, and here is an example of some of the Assert calls that can be made: Contains - Whether a string contains a certain word Empty - Whether an IEnumerable is empty Equal - Pass in an expected and actual value c.BasePrice = entity.BasePrice; The CategoryService class is constructor injected with AppJune2020DbContext class.This class is the base class for EntityFrameworkCode (EFCore). This typically is implemented as Assert.Fail (message). mockRepo.Setup(repo => repo.GetAsync()).ReturnsAsync(GetTestCategories()); } return View(category); // stey on Same View with validation error messages Finally the ones that inspect an action and the things that happened around this action. Once debugging is done, the Test Explorer will show the test result as shown in figure 9. The code in listing 8 performs following operations: The Mock instance is created using the IService interface. Before we do anything else, we need to make sure that we reference any projects that we are testing in our xUnit project. Assertions that operate over a value. var controller = new CategoryController(mockRepo.Object); A small component in the sense, it could be any function, any property or any class which is handling the specific functionality. The Assert section of the code verifies the result from the PostAsync() method as BadRequestObjectResult and verifies the badRequestResult value as Model error after execution. In this section we’re going to see some assertions based on their type. ctx.Categories.Remove(c); How do we structure our test logic to know which assertion failed? Please see page 370 of xUnit Test Patterns for the latest information. The IService uses the Category class as type for TEntity type. var result = controller.Index().Result; return cat; } return View(category); // stey on Same View with validation error messages I’ve worked with MSTest and NUnit previously, but for whatever reason not with xUnit. Unit Testing is a software testing approach which performs at the time of the development to test the smallest component of any software. It is open-source and completely free to use. [HttpPut("id")] Please see page 474 of xUnit Test Patterns for the latest information. new Category(){CategoryRowId=2, CategoryId="Cat0002",CategoryName="Electrical",BasePrice=20 } Write the code in this method as shown in listing 8. Since we will be testing Index() method returning ViewResult with List of Categories, the test method name is Index_ReturnsViewResult_WithAListOfCategories(). { xUnit aka xUnit.net is a unit testing framework for the .NET. In the Assert section, verify that result you obtained matches the expected result. var result = controller.PostAsync(newCategory).Result; This is a generic method that takes a type parameter the type of exception we want to check for. For this post, I have assumed that you are already aware of xUnit Theory and I’m going talk to a little bit more about how we can write better descriptive tests using MemberData. try } GitHub repositories (17) . } This package is not used by any NuGet packages. The first assertion is Assert.Raises, it verifies that a event with the exact event args is raised. These are the top rated real world C# (CSharp) examples of Xunit extracted from open source projects. Finally it accepts another delegate that execute the action. await ctx.SaveChangesAsync(); Sign in { The important part in the code of listing 11 is the the Model error on the CategoryName property of the Category class. { public async Task, GetAsync() In the Act section, execute the test to obtain some result. In my next post we’re going through the third type of assertions. NUnit provides a rich set of assertions as static methods of the Assert class. id); To perform object mocking we need to install the Moq package in the project as shown in the figure 6. xUnit is a free, open source unit testing tool for .NET Framework applications. { In a previous post, we saw how to do an Inner join in C#...

The test method is applied with the, To use xUnit to test the CategoryController, we need to add a reference of the ASP.NET Core Project in the test project. { services.AddScoped, CategoryRepository>, catService) return View(new Category()); Task, Products { get; set; } // expected one-to-many relationship var newCategory = GetTestCategory(); return Ok(cat); The Category class is shown in listing 2. { var controller = new CategoryController(mockRepo.Object); { I divided the assertions into three types. [HttpPost] return View(cats); Assert.Null(redirectToActionResult.ControllerName); He also blogs regularly at. Let's run the test project using F5 key. } var res = await ctx.Categories.AddAsync(entity); What Is xUnit Framework?

Sign up for a free GitHub account to open an issue and contact its maintainers and the community. The last part of the code is the Test Assertion, here the assertion check the result assertion type using Assert.IsType() method, this accepts the result returned from the controller's action method to verify that the result is. Copyright © 2009-2019 All Rights Reserved for DevCurry.com Assertions are central to unit testing in any of the xUnit frameworks, and NUnit is no exception. { I'm going to use the super-trivial and clichéd \"calculator\", shown below:The Add method takes two numbers, adds them together and returns the result.We'll start by creating our first xUnit test for this class. Since the Documentation for xunit is new, you may need to create initial versions of those related topics. In xUnit, the most basic test method is a public parameterless method decorated with the [Fact] attribute. Here we have to keep in mind that the Test method name should represent the actual test purpose. 3. var cat = await catService.GetAsync(id); 2. { The code further access the Index() method of the CategoryController class and receive its result. }, (); { public async Task, Index() Using the. // Assert mockRepo.Setup(repo => repo.CreateAsync(It.IsAny, ())) var cats = await catService.GetAsync(); // define the setup on the mocked type } Related articles. if (category.BasePrice < 0) throw new Exception("Base Price is wrong"); Custom Assertion The book has now been published and the content of this chapter has likely changed substanstially.
