Let's Start with POST operation

 Add the test steps to the feature file.

Feature: Users

       Operations about user

 

Background:

       Given I perform api operation on petstore server "https://petstore.swagger.io/v2/"

 

Scenario: Create user

       When I perform POST operation for User using endpoint "/user"

       Then I should see the response as successful with status code as 200 ok

5) Creating the Undefined Step Definitions

1. Right-click on any of the undefined steps in your scenario and select ‘Generate Step Definitions’
2. Make sure all the steps are checked and then click on ‘Copy methods to clipboard.
3. Open up ‘UsersSteps.cs’ class file and paste in all the undefined step definitions, Refer Json Body
4. {
5.   "id": 0,
6.   "username": "string",
7.   "firstName": "string",
8.   "lastName": "string",
9.   "email": "string",
10.   "password": "string",
11.   "phone": "string",
12.   "userStatus": 0
13. }

using System;

using TechTalk.SpecFlow;

 

namespace APIAutomation.Features

{

    [Binding]

    public class UsersSteps

    {

        [Given(@"I perform api operation on petstore server ""(.*)""")]

        public void GivenIPerformApiOperationOnPetstoreServer(string p0)

        {

            ScenarioContext.Current.Pending();

        }

       

        [When(@"I perform POST operation for User using endpoint ""(.*)""")]

        public void WhenIPerformPOSTOperationForUserUsingEndpoint(string p0)

        {

            ScenarioContext.Current.Pending();

        }

       

        [Then(@"I should see the response as successful with status code as (.*) ok")]

        public void ThenIShouldSeeTheResponseAsSuccessfulWithStatusCodeAsOk(int p0)

        {

            ScenarioContext.Current.Pending();

        }

    }

}

 

6) Now Start adding code for all Given, When and Then

using Microsoft.VisualStudio.TestTools.UnitTesting; //For asserting

using Newtonsoft.Json.Linq; //For Json object creation

using RestSharp; //For RestSharp operation

using System; //for Basic C# package

using TechTalk.SpecFlow; //for BDD package

 

namespace APIAutomation.Features

{

    [Binding] //It's binding the feature file with step definition file

    public class UsersSteps

    {

        public RestClient client;

        public RestRequest request;

        public IRestResponse response;

 

        [Given(@"I perform api operation on petstore server ""(.*)""")]

        public void GivenIPerformApiOperationOnPetstoreServer(string baseUrl)

        {

            //Create a Request pointing to the Service Endpoint

            client = new RestClient(baseUrl);

        }

 

        [When(@"I perform POST operation for User using endpoint ""(.*)""")]

        public void WhenIPerformPOSTOperationForUserUsingEndpoint(string endpoint)

        {

            //Create a JSON request which contains all the fields

            JObject jobj = new JObject();

            jobj.Add("id", 1);

            jobj.Add("username", "Raju");

            jobj.Add("firstName", "Raj");

            jobj.Add("lastName", "kumar");

            jobj.Add("email", "rajkumar@gmail.com");

            jobj.Add("password", "raju123");

            jobj.Add("phone", "9876543217");

            jobj.Add("userStatus", 1);

 

 

            //Add JSON body in the request and send the Request

            request = new RestRequest(endpoint, Method.POST);

 

            //Adding Json body as parameter to the post request

            request.AddParameter("application/json", jobj, ParameterType.RequestBody);

 

            //execute the request

            response = client.Execute(request);

        }

 

        [Then(@"I should see the response as successful with status code as (.*) ok")]

        public void ThenIShouldSeeTheResponseAsSuccessfulWithStatusCodeAsOk(int status)

        {

            //Converting the status code from response to integer format

            int statusCode = (int)response.StatusCode;

 

            //Asserting the status code from the response

            Assert.AreEqual(status, statusCode, "Statuscode is not a " + status);

        }

    }

}

 

7)Executing the feature file follow below steps

• Go to Build Tool bar=>Build Solution and click
• Go to Test Tool Bar =>Click on Test Explore

Once build successful right click on created scenario in Test Explorer and Run the test
