SpecFlow Tutorial for Automation Testing

The Cucumber blog argues that Cucumber.js is best due to its focus on good communication through plain language steps, whereas other JavaScript BDD frameworks are more code-y. (Keep in mind, though, that Cucumber would naturally boast of its own framework.) Other comparisons are posted here, here, here, and here. Jasmine and Mocha are two of the most popular general-purpose JS test frameworks. Theydiffer in that Jasmine has many features included that Mocha does not. This makes Jasmine easier to get started but makes Mocha more customizable .

• Test thread affinity is a simple yet powerful way to control which tests run on which threads.
• Once the folders are created, we create a new Feature file – ToDoApp.feature by right-clicking on the folder to add a new item.
• In my personal experience, bug tickets for intermittent failures get far less traction than bug tickets for consistent failures.
• Behat is the official Cucumber version for PHP, and as such is seen as the more “pure” BDD framework.
• “Hooks” are special methods that run before or after special points of execution.
• Here is a snippet of the SpecFlow+ Report showing both intermittent failures and consistent failures .
• This will be best suited for this SpecFlow tutorial for using SpecFlow Selenium C#.

Having transformed these steps, expressed in natural, readable language, into executable code, that’s where the responsibility of SpecFlow ends. To further implement your test automation so that it actually communicates with your application under test, you will need to add other tools to your test automation solution. Below is a binding class named DuckDuckGoStepswith step definitions for the three Gherkin steps from the DuckDuckGo search test. The constructor receives the Actor object via dependency injection from SpecFlow through scenario context.

How Q2 uses BDD with SpecFlow for testing PrecisionLender

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 https://globalcloudteam.com/ using SpecFlow+ Runner, which is SpecFlow’s own test runner that comes with advanced options and reports in the HTML, XML, and JSON formats. This is where you’ll add scenarios in Given-When-Then format.

Both tools use Gherkin as the language for writing test scenarios, which consist of steps that describe the given, when, and then of a feature. However, there are some differences between the two tools. Furthermore, SpecFlow supports parallel execution of scenarios and features while Cucumber requires additional plugins or configurations what is specflow used for to run tests in parallel. Behavior Driven Development is a practice in which developers and QA testers write automated user acceptance tests which satisfy acceptance criteria in user stories. This helps developers write code that is focused on satisfying business criteria which define the purpose of the software they are writing.

Pipe Character Escape for Gherkin Tables

When a project containing SpecFlow feature files is compiled, the output is a NUnit test assembly. Any NUnit-compatible test runner or existing CI infrastructure can be then used to execute the test specifications with no additional configuration to conduct the automated software testing. SpecFlow, also known as Cucumber for .NET is an open-source tool used for automating .NET applications. These tools are bridges between the business language and technical language. SpecFlow is an open-source version of Cucumber for the .Net framework. Using SpecFlow with Selenium C#, BDD tests can be generated using the Gherkin language and executed using the NUnit test framework.

What is Behavior-Driven Development (BDD)

Running up to 100 tests in parallel turned functional tests into de facto load tests. 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. Developers resolved many performance issues and significantly boost the app’s response times and load capacity. When the PrecisionLender team first started automating Boa tests, they ran tests one at a time.

The Boa test solution architecture, including Continuous Integration through TeamCity and parallel testing with SpecFlow+ Runner and Selenium Grid. Bas teaches companies around the world how to improve their testing efforts through test automation. He is an independent trainer, consultant and developer living in the Netherlands. When he’s not working he likes to take his bicycle for a ride, go for a run or read a good book. We’ll see more about the SpecFlow Visual Studio integration in the next article, where we will see how to get started with using it. A library that generates human-readable reports, often in HTML format.

SpecFlow School

I use JavaScript, Selenium, C#, email testing libraries, database testing libraries in combination with BDD with SpecFlow. I am able to use all these with SpecFlow to make my automation framework to be able to automate any kind of automated testing. The Web API project has an appsettings.json file in which a WeatherDatabaseSettings section is present with values for a MongoDB connection string, database name and collection name. You can add a matching appsettings.json file to your SpecFlow project in which you replace the value for DatabaseName with a test database used exclusively for the integration testing.

The user can then login and see a picture of a happy dog. Reusing the same code through the implemented Gherkin statement saves test automation time and thus reduces cost. The new Web API project template includes a weather forecasts controller. In my sample I updated the project to use a repository interface with an implementation that persists entities to a MongoDB database. Next add the following to the Web API .csproj file, replacing the value with the name of your SpecFlow project. This file contains bidirectional Unicode text that may be interpreted or compiled differently than what appears below.

Tools & Services

It uses an example or Scenario to characterize the system or feature being created. For example, if you’re making a basic Calculator App, the many behaviors include addition, multiplication, division, and so on. BDD is a communication and cooperation tool since it connects critical stakeholders, such as product owners, developers, and testers.

I’mnot saying that teams shouldn’t do BDD practices, and I’mnot saying that the Three Amigos should be separated. Example Mapping is one of the most useful practices a development team can do. I’m also not saying that BDD frameworks should be used for all testing purposes – they are poorly suited for unit testing and for performance testing. This new feature file eliminates the first two scenarios and uses a Background section to cover the setup steps. It also eliminates the need for special Given steps in each scenario to set unique starting points.

Benefits to the business

Gherkin uses a syntax of keywords and phrases to define scenarios, and each scenario consists of steps in a specific format – Given, When, Then. Then the article explains how to create a scenario with an example. You will learn how to write the step definitions that bind the statements in the test scenario to the application code. You will also learn how create the page objects that will drive your tests and how to generate and manage the bindings. Today there is a wide choice of test automation frameworks.
