These tags are used to identify and group related scenarios or scenarios that will be run together at some point. Choose a target framework and your preferred test automation framework and complete the wizard. In this SpecFlow automation tutorial, we’ll be using NUnit from here on, and I’ll explain along the way the NUnit methods. BDD is built on TDD (Test-driven development), which makes it an approach where tests are written first.
We were finally able to fix a major bug that happens during the parallel execution of scenarios and was a problem for a lot of users. Parallel execution on feature-level what is specflow should work now without problems. If you have still one, please create an issue on GitHub. BDD may generate reusable, modular, and maintainable automated tests.

3) Make a new class called “CalculatorApplication” that will serve as our test application. This is a basic class including functions for doing addition, multiplication, division, square root, and other operations on the provided input. 2) Copy the auto-generated code and paste in respected file of a step definition. Below are the steps to generate the step definition is specflow. Gherkin a simple language which is easily understood by the human. A scenario is a collection of test steps to perform an activity.
- The core of the BDD process is the ‘User Stories’ and the developers have to first write the user story.
- I am using Visual Studio 2022, but you can use an older version to follow along.
- Is a free (open-source) automation framework for web applications that work with many browsers and operating systems; further information is available here.
- Once development begins, they can collaborate toward a unified objective of identifying user stories.
- As a result of BDD, all stakeholders will first gather to decide on the application’s behavior.
- When this line is executed, the above error will be thrown.
BDD uses the Gherkin language, which helps determine test scenarios without technical knowledge. SpecFlow is a BDD-style testing framework that uses natural language to specify your tests. Selenium is a browser automation framework used in combination with a programming language like C#. The Cucumber files use the extension .feature, and the scenarios must follow syntax rules called Gherkin.
Performance Testing
Use SpecFlow to define, manage and automatically execute human-readable acceptance tests in .NET projects (Full Framework and .NET Core). TestingBot has a large grid of machines and browsers, which means you can use our service to do efficient parallel testing. It is one of the key features we provide to greatly cut down on your total testing time. You can learn more about the Output API and its usage in ourdocumentation. To use it, you simply update the SpecFlow NuGet packages to the latest version, and you are ready to go.
The examples used will be based on testing a C# object, which will be a basic calculator. Parallel Testing means running the same test, or multiple tests, simultaneously. Automation testing using Selenium Grid has scalability concerns; https://www.globalcloudteam.com/ hence remote Selenium Grid is advised for better test coverage. Existing tests may be converted to a more scalable Remote Selenium Grid by making minor modifications to the existing local Selenium WebDriver implementation.

Take this certification to master the fundamentals of Selenium automation testing with C# and prove your credibility as a tester. Given – Given in Gherkin is akin to Arrange in a unit test. It describes a set of pre-conditions for the scenario. In the above example, the precondition is that the user should be on the DuckDuckGo home page. ‘Conversation’ is the heart & soul of the BDD process and everything after that is optional.
In this SpecFlow automation tutorial, I’ll demonstrate how a BDD web test can be written using SpecFlow and Selenium C# and how to run it on the cloud Selenium Grid with SpecFlow Actions. I am using Visual Studio 2022, but you can use an older version to follow along. If you are preparing for an interview you can learn more through SpecFlow interview questions.

Community & Support
Feature files are simple text files that contain Features and Scenarios. As Gherkin is used in this SpecFlow tutorial, creation of feature files does not require any technical know-how. Behavior Driven Development is sort of an extension of TDD . TDD is a programming practice where developers write code only if the automation tests have failed.
It also brings the best practices of Agile software development and can be used even if your team is making use of the Waterfall model. The first step in this SpecFlow tutorial is to understand BDD scenarios. TDD is based on the principles of 3A’s i.e. ‘Arrange, Act, and Assert’, and in BDD these are replaced by ‘Given, When, Then’. Tests are written in a simple English-like language that does not require any development or coding skills. This enables team members from different teams i.e. business analysis, development, product management, etc. to actively participate in the test creation & updation process. You don’t need to have coding knowledge while writing tests using the BDD approach, all the tests are written in simple English language.
Automation Frameworks
We need to install the SpecFlow.NUnit package since we’re utilizing the NUnit test framework with SpecFlow Selenium C#. In SpecFlow 3, the MsBuild.A generation package is required to build code-behind-the-files. If there are still any unimplemented steps after developing Step definitions, the Feature files give a visual manner of identifying the unimplemented applications. It highlights such actions in a distinct color, making it very clear that there are specific steps that have yet to be implemented. It makes writing acceptance test drivers for .NET applications that use ATDD .
Using the Gherkin language, we can build situations in simple English that anybody can understand. This introductory SpecFlow tutorial will cover everything you need to know about. SpecFlow helps to define, manage, and automatically execute human-readable tests in .NET projects.
To-Do App: Test with SpecFlow & Selenium WebDriver
And also, anybody can write this type of scenario without understanding the inner workings of a test automation framework. Before starting with SpecFlow automation, follow the steps above to install the SpecFlow extension and create a new SpecFlow project. Cucumber is one of the most important tools that support BDD. It provides a means to write tests everyone can understand regardless of their technical skills. Since all of these test scripts are written in plain English, they also serve as documentation for the project. SpecFlow is a framework for defining these scenarios in a more structured way and tying them to tests that run against the code.
