Unraveling SpecFlow: The Testing Framework for .NET Applications

SpecFlow is a futuristic testing framework that propels .NET applications to skyscraping heights! It leverages Gherkin, a tongue-in-cheek language, that automates acceptance tests and aids application developers to work alongside project stakeholders. Scenarios can be written in plain and simple English to make it easy for understanding and managing test cases.

Setting up SpecFlow for Acceptance Testing in Visual Studio 2019

To go on this exciting journey, one must undertake the following steps:

Step 1: Installing the SpecFlow Visual Studio Extension

The first step is to install the SpecFlow Visual Studio Extension. Vital for the harmonious fusion of SpecFlow with your Visual Studio environment. Here’s what you must do:

  • Open Visual Studio and click on Tools
  • Select Extensions and Updates
  • Click on Online
  • Search for SpecFlow for Visual Studio 2019 and click Download to initiate the installation process.

Step 2: Creating a New SpecFlow Project

Once the extension is installed, you must create a new SpecFlow project in Visual Studio. It’s simple as ABC! Follow the steps below:

  • Click on File > New > Project.
  • Select Visual C# and click on SpecFlow Project.
  • Voila! The SpecFlow project template will include pre-configured NuGet packages for SpecFlow, NUnit, and SpecFlow.NUnit that’ll come in handy for writing and running acceptance tests.

Step 3: Defining Feature and Step Definitions

SpecFlow enables users to write their acceptance test scenarios in a feature file. Every feature file consists of a list of scenarios written in Gherkin syntax. See the example below:

Feature: Login

As a user

I want to log in

So that I can access my account

Scenario: Login successful

Given I navigate to the login page

When I enter my valid credentials

And click on the login button

Then I should be redirected to the dashboard page

If you want to execute the above scenario, you need to define step definitions that map the Gherkin syntax to the actual code. But how can this be achieved? Follow these steps:

  1. Right-click on the feature file
  2. Select Generate Step Definitions

This will create a new C# file with empty step definitions for each step in the scenario. You can then implement each step definition with the corresponding code.

Step 4: Running Acceptance Tests

The final step revolves around executing acceptance tests:

  • Right-click on the feature file
  • Select Run SpecFlow Scenarios.

It’s that simple – this will run all the scenarios in the feature file and show the results in your IDE. Moreover, you can run your tests via the command line using the nunit3-console.exe tool, which is included in the NUnit NuGet package.


SpecFlow is an efficient and collaborative tool that can help you write and automate acceptance tests in a more sophisticated way. By following the steps outlined above, you can effortlessly set up and use SpecFlow in your Visual Studio environment and create robust and readable acceptance tests for your .NET applications.
