What Is BDD (Behavior Driven Development) Approach In Software Testing

In most of the software development, there’s a high chance that commonly used term Behavior-driven development (BDD) and Test Driven Development (TDD). Before moving ahead lets discuss some of key features of these two approach.
Behavioral Driven Development (BDD) and Test Driven Development (TDD) are software development approach. It improves the collaboration between technical team, non-technical teams, project manager, business team and stakeholders on respective application.

In this article we discuss on BDD framework and its advantages

Behavior Driven Development

It is a methodology to understand the behavior of the application in simple English text representation. In simple term, BDD framework makes better understanding of the application to all the roles in the project like, developer, tester, manager, business analyst without deep into technical aspects. Mainly used in agile software development process. It explore and illustrate the behavior of the application and finally it driver it for development of the application.

  • Usually approach used for Acceptance testing and Regression testing
  • In this approach focused more on application behavior rather than scripting part in front end.
  • These behavior of the application is written in a simple English text using Gherkin language.
  • So it easy to understand by Technical, Non-technical teams and Stakeholders.
  • Here team creates simple scenarios on how an application should behave from the end user’s perspective.
  • Goal is to improve communication between developer, tester, manager, business analyst and stakeholders. Everyone can read gherkin file to understand application behavior.
  • From the beginning and through out the process it involves all developer, tester, stockholder to engage strong communication in product development cycle.
  • Cucumber framework support BDD approach.


  • It provides strong collaboration between team (developer, tester, Stakeholders )
  • It gives high visibility on application behavior as well as progress.
  • It defines the ‘behavior’ of the application but not on ‘test’
  • Better communication between developers, testers and product owners.
  • Since BDD is explained using simple language, quick learning is possible.
  • Due to non-technical in nature, it can reach a wider audience.


  • Need some basic knowledge on TDD to work effectively in BDD approach.
  • For small project (waterfall approach) BDD is not suitable.
  • BDD can’t be effective if there is not clarity in specific feature of the application.
  • Tester who use BDD need technical skill to implement gherkin to code formats.


  • TDD basically used for unit testing by developer. It give more clarity how to design the software. BDD focused on behavior of the application written in simple English text using Gherkin language.
  • For non-programmer, TDD approach is difficult to understand. Since BDD written in normal English text it is easy to understand by non-programmer.
  • In TDD approach, only developer is focusing on coding part and only they now what has to be the goal. BDD enables developer and customer to work together to reach out end goal as all they can see expected need.
  • TDD useful more only to developer and it gives complete idea of code which they are written. As BDD focused on application behavior, Every one has the clarity about the outcome result, they can add or remove some of the behavior if required. It helps to proper estimate on over all process.

BDD tools

There are different tool available in market to achieve BDD approach they are,

  • Cucumber (works on java)
  • Jbehave (works on java)
  • SpecFlow (works on .net environment)

  1. You really make it appear really easy with your presentation but I find this matter to be actually something which I believe I would by no means understand. It sort of feels too complex and extremely broad for me. I am looking ahead on your next submit, I’ll try to get the hang of it!

  2. Excellent website you have here but I was wanting
    to know if you knew of any message boards that cover the same
    topics discussed in this article? I’d really like
    to be a part of community where I can get suggestions from other
    experienced individuals that share the same interest.
    If you have any recommendations, please let me know.
    Thanks a lot!

  3. Howdy! I know this is kinda off topic but I was wondering which blog platform are you using for this site? I’m getting fed up of WordPress because I’ve had problems with hackers and I’m looking at options for another platform. I would be great if you could point me in the direction of a good platform.
