SpecFlow Table with CreateInstance

 

SpecFlow Table with CreateInstance

We will use the same example of the Users Feature and modify it to suit our needs. Before proceeding, please review the first section of Data Driven Testing and see how the basic functionality works for the Users Scenario.

1) Add a New Step

The first step is to create a new Step that will accept data in the form of a table. It is once again simple to specify data for the step in Vertical format. Simply enter the Fields and their Values. 

Users.feature file

Feature: Users

       Operations about user

Background:

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

Scenario: POST operation with table using createinstance

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

| Id | username | firstname | lastname | email      | password  | phone      | userstatus |

| 4 | Hithesh  | Hitesh   | Patil    | hitesh.p@gmail.com | hitesh123 | 9253746564 | 2        |

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

 

2)Create Plain C# class object

<T> stands for Type, which means that any type of object can be used. It could be a string, an integer, or a Class Object. In our case, we need to create a simple C# class with a lot of int and string objects.

Make a new folder in the solution called Modules. Then, in the same folder, create a new C# class called User and run it.

User.cs File

using System;

using System.Collections.Generic;

using System.Linq;

using System.Text;

using System.Threading.Tasks;

 

namespace APIAutomation.Modules

{

    class User

    {

        public int id { get; set; }

        public string username { get; set; }

        public string firstName { get; set; }

        public string lastName { get; set; }

        public string email { get; set; }

        public string password { get; set; }

        public string phone { get; set; }

        public int userStatus { get; set; }

    }

}

3)Step Definition Method

The CreateInstanceT> method will create a User and set its properties based on what is read from the table. It will also use the appropriate casting or conversion to convert your string to the correct type.

This table's headers can be "Field" and "Value," or anything else you want. What is important is that the first row contains the property name and the second row contains the value.

   User values = table.CreateInstance<User>();

Or

  var values = table.CreateInstance<User>();

        public IRestResponse response;

 

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

        public void GivenIPerformApiOperationOnPetstoreServer(string baseUrl)

        {

            //Make a Request that points to the Service Endpoint.

            client = new RestClient(baseUrl);

        }

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

        public void WhenIPerformPOSTOperationForUserUsingEndpointByCreatingcreateinstance(string endpoint, Table table)

        {

            var values = table.CreateInstance<User>();

                JObject jobj4 = new JObject();

                jobj4.Add("id", values.id);

                jobj4.Add("username",values.username);

                jobj4.Add("firstName",values.firstName);

                jobj4.Add("lastName", values.lastName);

                jobj4.Add("email", values.email);

                jobj4.Add("password",values.password);

                jobj4.Add("phone",values.phone);

                jobj4.Add("userStatus", values.userStatus);

        

            //Add a JSON body to the request and send it.

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

            //Adding Json body as parameter to the post request

            request.AddParameter("application/json", jobj4, 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 response status code to integer format

            int statusCode = (int)response.StatusCode;

            Console.WriteLine(response.Content);

            // Asserting the response's status code

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

        }

    }

}
