Which one exactly you need depends on the type of database engine you’re using. Apart from .NET applications, which are the applications that are created with the help of C# programming language, it supports Xamarin and Mono, which are the frameworks of .NET applications. One major hurdle in using the local Selenium Grid is that it cannot be scaled for full-fledged automated cross browser testing. I have shown below the Feature file for the To-Do app – Scenario steps are created based on all the tasks that need to be performed in the test i.e. When the prerequisite packages are installed based on the steps mentioned in this SpecFlow tutorial, you can verify the status and also check if there are any package updates required. SpecFlow is an open-source tool that aids BDD in the .net framework.
This will be best suited for this SpecFlow tutorial for using SpecFlow Selenium C#. Before updating to the latest version of SpecFlow, it is recommended that you take a back-up of the project as you may encounter build/compilation errors after the update. Take this certification to master the fundamentals of Selenium automation testing with C# and prove your credibility as a tester. 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’.

As PrecisionLender welcomes more customers, the Boa solution will be ready to scale with more tests, more configurations, and more executions. Appium is an open source test automation framework for use with native, hybrid and mobile web apps. It drives iOS, Android, and Windows apps using the WebDriver protocol. Appium is built on the idea that testing native apps shouldn’t require including an SDK or recompiling your app. And that you should be able to use your preferred test practices, frameworks, and tools.
In this SpecFlow tutorial for automation testing with Selenium, we will demonstrate the usage of SpecFlow Selenium C# particularly for cross browser testing related scenarios. SpecFlow gives complete Visual Studio debugger support, allowing setting of breakpoints on Given/When/Then lines in the feature files and step through their execution. Third, continuous testing boosts customer confidence in PrecisionLender. Customers trust the software quality because they know that PrecisionLender thoroughly tests every release. The PrecisionLender team also shares SpecFlow+ LivingDoc reports with specific clients to prove quality. The team chose SpecFlow to be the core framework for Boa tests.
Cucumber does not provide any such feature and this is one major drawback for this tool for automated software testing. When test scripts are being written for a very large project, there are hundreds of test scenarios. Creating test scripts for these scenarios and remembering them while writing becomes cumbersome. SpecFlow provides a feature named Auto-Complete, with Visual Studio integration, using which the phrases can be automatically completed in test scripts. SpecFlow uses the official Gherkin parser and provides integration to the .NET framework, Silverlight, Windows Phone, and Mono for automated software testing. Since all of these test scripts are written in plain English, they also serve as documentation for the project.

Furthermore, one of PrecisionLender’s developers loved BDD practices so much that he joined the team of SETs! Through Gherkin, SpecFlow provided a foundation that enabled quality work to shift left. SpecFlow+ LivingDoc enabled the PrecisionLender team to turn Gherkin feature files into living documentation.
SpecFlow increases the amount of efficient collaboration, by using the BDD approach, and hence it reduces the time of development. BDD ensures that every contributor remains on the same page, and does not face any technical challenges while contributing to writing test scenarios. BDD uses the Gherkin language, which helps determine test scenarios without technical knowledge. The approach of this technique is to use language that could be easily understood even by a non-technical personality.
- The next important step in this SpecFlow tutorial is to create Step Definitions for each Scenario Step that is present in the Feature file.
- Product owners would create user stories, but developers would struggle to understand requirements and business purposes fully.
- It manages the browser’s lifetime and offers simple configuration options and Selenium helper methods.
- TestingBot provides automated and manual testing of websites and mobile apps.
- Reliability also means that engineers spend less time on automation maintenance and more time on more valuable activities, like developing new features and adding new tests.
- From SpecFlow 3 onwards, app.config file is deprecated instead specflow.json will be used to configure SpecFlow.
For this particular SpecFlow automation tutorial, I used the XPath locator for the web elements on the page because the web elements do not have unique IDs. XPath is one of the most used locators in Selenium WebDriver for navigating across a page’s HTML structure. Any element on a web page can be located using the HTML DOM framework for both HTML and XML documents. These tags are used to identify and group related scenarios or scenarios that will be run together at some point. Then, add one .json file for each environment where you want to run your tests.

The team then started running up to 3 tests in parallel on one machine, but that also was not fast enough. They turned to Selenium Grid, a tool for running WebDriver sessions remotely across multiple machines. Playwright supports all modern rendering engines including Chromium, WebKit, and Firefox. Test on Windows, Linux, and macOS, locally or on CI, headless or headed.
Whereas the SpecFlow+ Runner report focuses on automation execution, the SpecFlow+ LivingDoc report focuses on behavior specification apart from coding and automation details. LivingDoc displays Gherkin scenarios in a readable, searchable way that both internal folks and customers can consume. It can also optionally include high-level pass-and-fail results for each scenario, providing just enough information to be helpful and not overwhelming. LivingDoc has also helped PrecisionLender’s engineers identify and eliminate unused step definitions within the automation code. PrecisionLender benefits greatly from complementary reports from SpecFlow+ Runner and SpecFlow+ LivingDoc. When a project containing SpecFlow feature files is compiled, the output is a NUnit test assembly.
In this article, we’ll take a look at some of the tools that are frequently combined with SpecFlow to create different kinds of acceptance tests. Today there is a wide choice of test automation frameworks. Which one to use depends mainly https://globalcloudteam.com/ on the peculiarities of your projects. As for SpecFlow, it is very similar to Cucumber and focuses on meeting the needs of behavior-driven development. What makes it special is that it is designed especially for .Net projects.
Unit testing frameworks
BDD is a variation of ATDD , the major difference being the focus is now on ‘behavior’ rather than ‘test’. That is what we will try to understand better in this SpecFlow automated software testing with specflow tutorial. Enter NUnit in the search edit box within the Create a new project window. Then choose the option NUnit Test Project(.NET Core) from the result dropdown.
The Boa test solution architecture, including Continuous Integration through TeamCity and parallel testing with SpecFlow+ Runner and Selenium Grid. The actual implementation is fairly similar to a Selenium implementation, except this time we are using the methods provided by SpecFlow Actions. Most of the browser capabilities are optional, but they are helpful when you need specific configurations or want to personalize the results, for example with the build and project names. Each scenario consists of a series of actions that the Cucumber must perform. Cucumber checks whether the program matches the specification and produces a report stating if each scenario was successful or unsuccessful. While SpecFlow does a great job of creating executable specifications that are readable for all stakeholders, the code that is executed when these specifications are verified is just as important.
Testing at scale repeatedly uncovered performance bottlenecks in the app. Performance issues caused widespread test failures that were difficult to diagnose because they appeared intermittently. Still, the visual timeline and timestamps in the SpecFlow+ Runner report helped the team identify periods of failure that could be crosschecked against backend logs, metrics, and database queries. Developers resolved many performance issues and significantly boost the app’s response times and load capacity.
Real Time Web Testing
To go to a Step Definition, just right click on the Scenario Step and select “Go To Step Definition”. Once the project is set up, we install the necessary packages required for executing the code. From SpecFlow 3 onwards, app.config file is deprecated instead specflow.json will be used to configure SpecFlow. Though using the specflow.json is optional for full framework projects, migration is recommended. This SpecFlow Tutorial for beginners and professionals will help you learn how to use SpecFlow framework with Selenium C# for performing Selenium automation testing.
Introduction To Behavior Driven Development (BDD)
Developing a continuous testing solution brought many incredible benefits to PrecisionLender. First, the quality of the PrecisionLender app improved because continuous testing provided fast feedback on failures that developers could quickly fix. Instead of relying on manual spot checks, the team could trust the comprehensive safety net of Boa tests to catch bugs.
How BDD and Agile Together Make Testing Efficient
Good test cases are more than just verification procedures – they are behavior specifications. The team also wanted to share Boa tests with specific customers without sharing the entire automation code. SpecFlow uses the official Gherkin parser, with support for over 70 languages – which means that you can write your Given/When/Then scenarios in languages other than English, too. Then, using bindings, these tests are connected to the application code, enabling you to run the tests using the testing framework of your choice .
Cucumber is an integration testing tool that allows you to write human-readable acceptance criteria for your application. BDD is an approach to agile software development that focuses on communication between developers and customers and is based on the idea of collaboration rather than working in isolation. SpecFlow helps automate the testing of features using Gherkin, the language that forms the foundation of BDD. BrowserStack Automate is a test automation platform for testing websites on 2,000+ real mobile devices and browsers. Devs and QAs rely on BrowserStack’s highly reliable cloud infrastructure to run thousands of tests in parallel and scale infrastructure effortlessly. Tesco, Shell, NVIDIA, Discovery, Wells Fargo, and over 50,000 companies have eliminated painful manual infrastructure operations by moving to BrowserStack’s platform.
This SpecFlow tutorial will help you understand how BDD can be leveraged by integrating SpecFlow Selenium C# files with end-to-end Selenium. Scoping functionality is available in Specflow which is not present in Cucumber. By defining the Scope, the same test definition can be used for executing multiple test scripts for automated software testing with SpecFlow. For example, if UI and functional test scripts are to be executed for the same test scenario, then in Specflow there is no need to create two different scenarios. While in Cucumber, for every test script there must be a different scenario.
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. PrecisionLender app performance at scale was a second big challenge. Running up to 100 tests in parallel turned functional tests into de facto load tests.
With BrowserStack Automate, teams can shrink build times to 5 minutes, release great software daily, and be happier while doing it. With SpecFlow, you can create test cases using simple Gherkin syntax and one of the seventy supported natural languages. This helps to establish solid communication between subject matter experts and developers as well as technical and non-technical team members. Then, created test cases are tied to the application code with the help of so-called bindings, giving you the opportunity to execute them using any preferred testing framework. Moreover, tests can be executed using SpecFlow+ Runner, which is SpecFlow’s own test runner that comes with advanced options and reports in the HTML, XML, and JSON formats. It offers freedom to users to create feature files without having any technical knowledge, thereafter, a tester binds the Gherkin language to its necessary source code.
