.net core WebAPI methods testing with xUnit

In this Article we can see .net core WebAPI methods testing with xUnit

Step 1: Create .net core WebAPI project 

Step 2: Create Model with below code

using System;

namespace WebAPI.Models

{

    public class Student

    {

        public int Id { get; set; }

        public string Name { get; set; }

        public string Email { get; set; }

    }

}

Step 3: Create WebAPI Control with below code 

using Microsoft.AspNetCore.Mvc;

using WebAPI.Models;

namespace WebAPI.Controllers

{

    [Route("api/[controller]")]

    [ApiController]

    public class StudentController : ControllerBase

    {

        [HttpPost]

        public ActionResult<string> CreateStudent(Student obj)

        {

            // you code here

            return "Data inserted successfully";

        }

        

    }

}

Step 4: Build the WebApi Project

Step 5: Create .net core xUnit Project.

Step 6: Create UnitTest class and add below code 

using Microsoft.AspNetCore.Mvc;

using WebAPI.Controllers;

using WebAPI.Models;

using Xunit;

namespace XUnitProject

{

    public class UnitTest1

    {

        [Theory]

        [InlineData(1, "Student 1", "Email1", "Data inserted successfully")]

        [InlineData(2, "Student 2", "Email2", "Data inserted successfully")]

        [InlineData(3, "Student 3", "Email3", "Data inserted successfully")]

        [InlineData(4, "Student 4", "Email4", "Data inserted successfully")]

        public void Test1(int Id, string Name, string Email, string ExpectedResult)

        {

            Student objStudent = new Student();

            objStudent.Id = Id;

            objStudent.Name = Name;

            objStudent.Email = Email;

            StudentController objStudentController = new StudentController();

            ActionResult<string> actionResult = objStudentController.CreateStudent(objStudent);

            string result = actionResult.Value;

            Assert.Equal(ExpectedResult, result);

        }

    }

}

Step 7: Right click on Test Method and select "Run Test(s)"
