SpecFlow - Table Conversion to Dictionary

---

---

Tables can hold data in a horizontal and vertical direction in the Feature File. With a Dictionary object, we shall see how to access data in the Feature File vertically in a key-value pair.

Step 1: Create a Feature File

The details of how to create a Feature File is discussed in detail in the Chapter − Feature File.

Feature: User credential
Scenario: Login module
   When User types details
   | KY       | Val            |
   | username | tutorialspoint |
   | password | pwd1           |
Then user should be able to login

Step 2: Create C# File to Access Table Data

We must convert a Table to a Dictionary via System.Collections.Generic package. We shall create a new folder within the project and have a C# file in it. Right-click on the SpecFlow Project, then click on Add.

Select the option New Folder.

Give the name Utils to the folder.

Right-click on the new Folder created, then select the option Add. Click on Class.

Project Folder Structure

C# Class Implementation

using System;
using System.Collections.Generic;
using System.Text;
using System.Data;
using TechTalk.SpecFlow;
namespace SpecFlowProject1.Utils {
   class Class1 {
      public static Dictionary<string, string> ToDT(Table t) {
         var dT = new Dictionary<string, string>();
         
         // iterating through rows
         foreach (var r in t.Rows) {
            dT.Add(r[0], r[1]);
         }
         return dT;
      }
   }
}

Step 3: Create a Step Definition File

The details of how to create a Step Definition File is discussed in detail in the Chapter − Step Definition File.

using System;
using TechTalk.SpecFlow;
namespace SpecFlowProject1.Features {
   [Binding]
   public class UserCredentialSteps {
      [When(@"User types details")]
      public void WhenUserTypesDetails(Table t) {  
         
         //Accessing C# class method from Step Definition
         var dict = Utils.Class1.ToDT(t);
         Console.WriteLine(dict["username"]);
         Console.WriteLine(dict["password"]);
      }   
      [Then(@"user should be able to login")]
      public void ThenUserShouldBeAbleToLogin() {
         Console.WriteLine("User should be able to login");
      }
   }
}

Step 4: Execution & Results

Select User credential(1) Feature, then click on Run All Tests in View.

Select Login Module Scenario, then click on Open additional output for this result link.

The Scenario got executed with data passed from a Table (converted to a Dictionary) in the Feature File within the When step.
