I have a unit test project using Xunit and the method we are testing returns IActionResult.
I saw some people suggest using "NegotiatedContentResult" to get the content of the IActionResult but that doesn't work in Xunit.
So I wonder how to get the content value of an IActionResult in Xunit?
Test code example is provided below:
public void GetTest() { var getTest = new ResourcesController(mockDb); var result = getTest.Get("1"); //Here I want to convert the result to my model called Resource and //compare the attribute Description like below. Resource r = ?? //to get the content value of the IActionResult Assert.Equal("test", r.Description); } Does anyone know how to do this in XUnit?

xUnit uses the [Fact] attribute to denote a parameterless unit test, which tests invariants in your code. In contrast, the [Theory] attribute denotes a parameterised test that is true for a subset of data. That data can be supplied in a number of ways, but the most common is with an [InlineData] attribute.
Testing a positive case This method is decorated with the Fact attribute, which tells xUnit that this is a test.
Here is the list of attributes removed from the framework: [Setup] and [TearDown] are replaced with Constructors & IDisposable. [TestFixture] is removed. [Ignore] is absorbed with Skip = parameter on [Fact]
Ok(object) is a controller method that returns a new OkObjectResult(object); the OkResult class implements an ActionResult that produces an empty 200 response. the OkObjectResult class implements an ActionResult that process a 200 response with a body based on the passed object.
Depends on what you expect returned. From previous example you used an action like this.
[HttpGet("{id}")] public IActionResult Get(string id) { var r = unitOfWork.Resources.Get(id); unitOfWork.Complete(); Models.Resource result = ConvertResourceFromCoreToApi(r); if (result == null) { return NotFound(); } else { return Ok(result); } } That method will either return a OkObjectResult or a NotFoundResult. If the expectation of the method under test is for it to return Ok() then you need to cast the result in the test to what you expect and then do your assertions on that
public void GetTest_Given_Id_Should_Return_OkObjectResult_With_Resource() { //Arrange var expected = "test"; var controller = new ResourcesController(mockDb); //Act var actionResult = controller.Get("1"); //Assert var okObjectResult = actionResult as OkObjectResult; Assert.NotNull(okObjectResult); var model = okObjectResult.Value as Models.Resource; Assert.NotNull(model); var actual = model.Description; Assert.Equal(expected, actual); } If you love us?
