Unit Test WebAPi

I have this controller and I want to create a unit test for it , I have a small experience with unit testing but now I want to learn it , I'm using Dto here and automapper .

using System;
using System.Collections.Generic;
using System.Data;
using System.Data.Entity;
using System.Data.Entity.Infrastructure;
using System.Linq;
using System.Net;
using System.Net.Http;
using System.Web.Http;
using System.Web.Http.Description;
using AutoMapper;
using WebAPiBackend.Dto;
using WebAPiBackend.Models;
namespace WebAPiBackend.Controllers
{
[AllowAnonymous]
public class SpecialitiesController : ApiController
{
private ApplicationDbContext db = new ApplicationDbContext();
//// GET: api/Specialities
//public IQueryable GetSpecialities()
//{
// return db.Specialities;
//}
//get with Dto Done
public IEnumerable GetSpecialities()
{
var specQuery = db.Specialities;
return specQuery
.ToList()
.Select(Mapper.Map);
}
//DTO
// GET: api/Specialities/5
[ResponseType(typeof(Specialities))]
public IHttpActionResult GetSpecialities(int id)
{
//Specialities specialities = db.Specialities.Find(id);
Specialities specialities = db.Specialities.SingleOrDefault(c => c.SpecialtyId == id);
if (specialities == null)
{
return NotFound();
}
return Ok(Mapper.Map(specialities));
//return Ok(specialities);
}
//DTO
// PUT: api/Specialities/5
[ResponseType(typeof(void))]
public IHttpActionResult PutSpecialities(int id, SpecialitiesDto specialitiesDto)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
var speciinDB = db.Specialities.SingleOrDefault(c => c.SpecialtyId == id);
if (speciinDB == null)
return NotFound();
Mapper.Map(specialitiesDto, speciinDB);
db.SaveChanges();
return Ok();
}
// POST: api/Specialities
[ResponseType(typeof(Specialities))]
public IHttpActionResult PostSpecialities(SpecialitiesDto specialitiesDto)
{
if (!ModelState.IsValid)
{
return BadRequest(ModelState);
}
//addingforDTo
var specialDTO = Mapper.Map(specialitiesDto);
db.Specialities.Add(specialDTO);
db.SaveChanges();
specialitiesDto.SpecialtyId = specialDTO.SpecialtyId;
return CreatedAtRoute("DefaultApi", new { id = specialDTO.SpecialtyId }, specialitiesDto);
}
// DELETE: api/Specialities/5
[ResponseType(typeof(Specialities))]
public IHttpActionResult DeleteSpecialities(int id)
{
Specialities specialities = db.Specialities.Find(id);
if (specialities == null)
{
return NotFound();
}
//db.Specialities.Remove(specialities);
specialities.IsDeleted = true;
db.SaveChanges();
return Ok(specialities);
}
protected override void Dispose(bool disposing)
{
if (disposing)
{
db.Dispose();
}
base.Dispose(disposing);
}
private bool SpecialitiesExists(int id)
{
return db.Specialities.Count(e => e.SpecialtyId == id) > 0;
}
}
}

HI Alaya,

The below link can help you to connect Unit testing with Web API.

https://docs.microsoft.com/en-us/aspnet/web-api/overview/testing-and-debugging/unit-testing-with-aspnet-web-api

You have a step by step process to create sample unit test method. Please refer it.

Thanks.
