C# WebApi Testing with WebApiTestClient

WebApiTestClient is a tool designed to test C# WebApi interfaces, which is very easy to use. Here are the basic steps to perform interface testing using WebApiTestClient:

1. Firstly, create a new C# console application project in Visual Studio.
2. Install the WebApiTestClient NuGet package in your project. You can search for WebApiTestClient in the NuGet Package Manager and install it.
3. Create a new test class in the project to write interface testing code.
4. In the test class, utilize the methods of WebApiTestClient to send HTTP requests and retrieve responses. For example, you can use the GetAsync method to send a GET request, and the PostAsync method to send a POST request.
5. Write test code to verify if the return results of the interface meet the expected outcome. Assertion statements can be used to compare the actual results with the expected results.
6. Run the test class to view the test results.

Here is a simple example code demonstrating how to use WebApiTestClient to test a GET endpoint:

using System;
using System.Net.Http;
using System.Threading.Tasks;
using WebApiTestClient;

class Program
{
    static async Task Main(string[] args)
    {
        var client = new TestClient("http://localhost:5000/api/");

        HttpResponseMessage response = await client.GetAsync("example");

        if (response.IsSuccessStatusCode)
        {
            string responseBody = await response.Content.ReadAsStringAsync();
            Console.WriteLine(responseBody);
        }
        else
        {
            Console.WriteLine("Error: " + response.StatusCode);
        }
    }
}

In the example above, first create a TestClient instance, specifying the interface address to be tested. Then use the GetAsync method to send a GET request and output the corresponding information based on the response result.

By using this method, it is very convenient to use the WebApiTestClient tool to test C# WebApi interfaces.
