Software development often involves using a lot of code written and maintained by others\u2014and testing is no different. If your team is interested in implementing behavior-driven development (BDD), you\u2019ve probably come across many different frameworks promising to simplify the process, but it can be difficult to decide on the best option.
<\/p>\n\n\n\n
In this article, we will take a look at BDD framework options for each major programming language, as well as some tips for deciding on the right framework for your organization.

There\u2019s no shortage of BDD frameworks for each major programming language\u2014how do you decide which one to use?<\/p>\n\n\n\n
Behavior-driven development, or BDD, is a set of practices designed to reduce wasteful behavior in software development. At its core, BDD involves thinking through desired outcomes and API structure before writing any code. Automated tests are a byproduct of the process that drives implementation.
<\/p>\n\n\n\n
BDD can be divided into two parts:
<\/p>\n\n\n\n
BDD often occurs at the very beginning of the software development cycle after a user story is written. The deliberate discovery meeting produces high automated tests that describe the outcomes of a user story. Developers use this as a starting point for lower level test-driven development, or TDD.<\/p>\n\n\n\n
BDD test automation frameworks read executable specifications written in plain text (e.g., Gherkin or other domain-specific languages, or DSLs) and validate that the software does what those specifications promise. The framework generates a report that indicates a success or failure for each specification.Download our free list of must-have BDD development tools to support your implementation.Download Now<\/a><\/p>\n\n\n\n There is a BDD automation framework for every major programming language. These frameworks are generally derivatives of Cucumber or JBehave, but some are non-Gherkin spec runners that have BDD-like features. They all strive to achieve the same goal but use different methodologies. Let\u2019s take a look at some of the most popular BDD frameworks for each major programming language.<\/p>\n\n\n\n SpecFlow<\/a> is the most popular BDD framework for Microsoft .NET languages. While there is a free and open source version, it requires a separate unit test runner (e.g., Unit or MSTest) in order to run scenarios. The premium version, known as SpecFlow+, provides a BDD-friendly runner, Microsoft Excel integrations, living documentation and premium support. Alternative BDD frameworks for Microsoft .NET languages include: Cucumber-JVM<\/a> and JBehave<\/a> are the two most popular BDD frameworks for Java and popular JVM languages (e.g., Scala and Closure). JBehave is one of the original BDD frameworks developed by BDD Godfather Dan North, but it lacks some common Gherkin features, whereas Cucumber-JVM is fully Gherkin-compliant solution. Alternative BDD frameworks for Java and JVM languages include: Jasime<\/a> and Mocha<\/a> are the two most widely used TDD frameworks for JavaScript, but they lack a full set of BDD features. Cucumber.js<\/a> and Yadda<\/a> have become the most popular BDD frameworks that add Gherkin or Gherkin-like syntax. Cucumber.js stays the closest to plain language step definitions, whereas Yadda is designed to be less invasive and flexible. Alternative BDD frameworks for JavaScript include: Behat<\/a> and Codeception<\/a> are the two most popular BDD frameworks for PHP. While Behat is the Cucumber-endorsed framework focused exclusively on BDD, Codeception may be more flexible as a programmer-focused testing framework that can handle many different types of tests, including API testing, unit testing and integration testing.<\/p>\n\n\n\n Behave<\/a> and Lettuce<\/a> are the two most popular BDD frameworks for Python, although they are hardly the only options available. Behave is Gherkin-compliant and similar to Cucumber, whereas Lettuce lacks some Gherkin features. Pytest-BDD<\/a> has also become increasingly popular given its integration with Pytest, which is a popular testing framework in the wider Python community. Alternative BDD frameworks for Python include:
