Behavior Driven Development – an Understandable Way of Testing

Behavior-driven development is an approach to software development, which has appeared from the test-driven development approach. The main peculiarity of it is the simple language, far from those complicated technical terms. The shared language of the BDD helps to improve communication among technical workers, managers, and stakeholders. A shared understanding of the requirements between the development and business team helps to guide the development process, increase flow and decrease rework.  In fact, the system is so simple, that even a person without an IT education could understand what is this about.

Both behavior-driven development and test-driven development are based on the tests, written ahead of the code. However, in BDD tests are based on the expected behavior of the system and the user. In this system, developer, tester and customer are working together at the automated system, able to run the acceptance tests according to the given data, and validate that the new behavior is always supported by the system.

What Is Behavior Driven Development: Features of the Approach

In behavior-driven development, a feature is a part of the code – it is the desired way for the product to function, and it often includes multiple behaviors. These features, as well as the other parts of the code, are written in simple common language. The desired behavior is described as a story with 3 main variables:

  1. As a… – it defines the person who acts;
  2. I want…– the desired action of the product;
  3. So that… – the desired outcome from the action.

The testers now can develop a scenario, based on this story. Most of the frameworks use common behavior driven development example template:

  1. Given – the context or story;
  2. When – the variable, which appears when something happens;
  3. Then – the desirable reaction of the product and outcome.

BDD is popular because it is a way to improve communication between the programmers, testers, and product owners. And the simplicity of the language results in the short learning curve as well. As a non-technical by nature approach, it can reach a wider audience.

However, this approach needs a strong knowledge of the test-driven development and the sufficient technical skills of the programmers. And it will work only if you have properly worked out requirements.

Behavior Driven Development Framework: Which to Choose

The choice of the behavior driven development framework depends on the peculiarities and needs of the project you are going to create. There are many unit-test frameworks, based on the coding languages.

  • CBehave – a framework, inspired by Cucumber; uses “feature+scenario” structure and “given-when-then” template for describing the scenario of the behavior; supports mock.

Behavior-driven development Python frameworks are:

  • Behave – backed up by Python code; for the tests uses the information written in the form of the natural language/
  • Lettuce – simple Cucumber-based tool, aiming the most common tasks of the BDD.

Frameworks for the behavior driven development PHP:

  • Behat – an open-source framework for PHP 5.3+; is focused on continuous communication and test-automation.
  • Codeception – in this tool all the tests are written in a descriptive manner and saved in PHP DSL files.

For the behavior driven development JavaScript there are:

  • Jasmine – independent of the other JS frameworks; does not require a DOM; is loved for the clear syntax, which is easy to write and read.
  • Mocha – has a command line program, built-in in the browser; allows testing in the server and client side environments.
