How to test IActionResult and its content in C#

To test an IActionResult and its content in C#, you can use the ActionResult class and its various subclasses to construct the result and then make assertions on its properties.

Here's an example of how to test an IActionResult that returns a JSON object:

[TestMethod] public void TestMyController() { // Arrange var controller = new MyController(); // Act var result = controller.Get(); // Assert Assert.IsInstanceOfType(result, typeof(ActionResult)); var contentResult = result as JsonResult; Assert.IsNotNull(contentResult); Assert.AreEqual(HttpStatusCode.OK, contentResult.StatusCode); dynamic content = contentResult.Value; Assert.AreEqual("John", content.FirstName); Assert.AreEqual("Doe", content.LastName); }

In this example, we define a test method named TestMyController that tests the Get method of a controller named MyController. We use the ActionResult class to construct the result and then make assertions on its properties.

First, we assert that the result is an instance of the ActionResult class. Next, we cast the result to a JsonResult and assert that it is not null. We then assert that the status code of the result is HttpStatusCode.OK. Finally, we access the content of the result as a dynamic object and make assertions on its properties.

Note that the specific assertions you need to make will depend on the content of the IActionResult. You can use the ActionResult class and its subclasses to construct results that return a wide variety of content types, including JSON, XML, HTML, and binary data.
