What is BDD? The role, Scope, and Benefits of BDD in Software Development

At the time of launching a brand new digital project, it is necessary to have a frequent connection between the engineers and the business team. This is important to make efficient use of time, effort, and resources.

However, one thing that can certainly help is following the right strategy to achieve your objectives. By improving communication between the two professionals, the progress of the project can be prevented from any kind of barriers or bottlenecks.

This is where BDD (behavior-driven development) plays its part. It helps an organization successfully assist its technical team to deliver the software project within the required time frame without getting into much hassle.

What Is BDD ( Behavior Driven Development)?

BDD basically stands for Behavior Driven Development, which is a high-level software project methodology. It uses the outside-in technique in which first we figure out the outside layer that defines the needs of a business.

The most important part of the project is the development phase. BDD is a technique that enables you to make the process easier by breaking up the project into smaller tasks and then concluding with solutions.

Development is a pretty challenging and complicated phase of a project, and resultantly many teams tend to miss the key elements. This vital element of the development process is to fulfill the specific requirements of a business.

To overcome these problems, top software development companies start their development project with a defined approach. The main goals and power of the software development cycle are based on a progressive and defined approach.

How Does Bdd Work

The first step in BDD software testing is to convert the given idea into a list of requirements between the outside and inside layers. Moreover, one crucial fact that is essential to remember while listing the requirements is that it should be so that everyone understands it.

And then, the cycle moves to its next steps. It includes figuring out the requirements and features and fulfilling the given standards to release the final product. What does a company expect to benefit from BDD? Teams who are already using TDD and ATDD consider BDD to drive several benefits.

They expect BDD to offer practical guidance on organizing the communication between different teams of developers, testers, and domain experts. Besides effective communication, tools targeting a BDD approach should automatically generate technical information.

To ensure that every team member gets the point, we accomplish flexibility with a story-driven implementation. This story will act as a natural language that everyone understands and clearly describes the desired outcome.


Parameters BDD TDD ATDD
Definition A developmental approach that mainly focuses on the behaviors of the system. A developmental approach that primarily focuses on the implementation of software features. A technique that is used to focus on defining the most accurate requirements.

Main Focus Knowing and understanding requirements Unit testing Defining the criteria for acceptance
Implementation Level High-Level Low-Level Low-Level
Development Stages Feature discussion, coding, creating scenarios, testing, refactoring Refactoring, coding Testing, coding, learning, and feedback
Input Documentation Requirement documentation, acceptance criteria Requirement documentation Requirement documentation

Why BDD is the Better Approach

It applies the “Five Whys” principle to every proposed user story. Thus ensuring that purpose is clearly related to business outcomes.

Defining “From the Outside in” means implementing those behaviors that contribute directly to the business outcomes.
Explains the behaviors in a single notation that is directly accessible to project domain experts, testers, and developers. It ensures efficient collaboration between the team.

Moreover, implementing these techniques all the way down to the lowest levels of abstraction of the software encourages us to pay attention to the distribution of behavior. Consequently, the progression of the project remains cheap.

However, it’s fair to say that Behavior Driven Development (BDD) is quite familiar with the TDD but differs in a way that focuses on the discussion among team members.

Examples of BDD Testing Frameworks

If you ever consider, “what is bdd framework?” It generally depends on some specific requirements of the organization. These frameworks can best support your applications and have a positive impact on how your teams might operate. Here are some of the most common examples of the BDD frameworks:

  • Quantum
  • Cucumber
  • SpecFlow
  • Gherkin
  • JBehave

Here is a basic breakdown of how these frameworks are likely to work:

Role Of BDD – Development Cycle

BDD mainly aims to develop code through the interactions between the developers and users with the help of an approach outside-in development. In practical terms, it is an idea to create examples that describe software behavior that the user evaluates.

However, it is crucial to guide software development through the BDD methodology. It is the responsibility of project managers to specify everyone their duties and allow the development of the tool in question.

The mock-ups of the software development plan are also created in this phase to stimulate system modules before writing them. Furthermore, using these tests will help create the opportunity for fast feedback before development.

The Scope Of Behavior-Driven Development

Before running a QA software test, BDD in the project requires the software developer and testers to answer the following detailed questions:

  • What is bdd, and where to begin the process?
  • What should be a part of the software test, and what should not be tested?
  • How often is it required to test?
  • What to name the testing process?
  • How do you find out the reason for test failure?

In simple words, BDD works on the unit and acceptance testing to avoid several common issues. However, most BDD suggest writing unit test names as complete sentences, starting with the conditional verb, i.e., “Should,” in English.

In addition, it suggests that all the written statements should be in clear business terms and in order of business-related values.
At the same time, the user story in BDD software development and testing projects is an informal way of using natural language to describe the specifications of the software system. These software specifications are described from an end-user view and are documented in the project’s index cards.

Moreover, some teams use BDD frameworks for collaboration and communication between the software developers, the QA team, and business or nontechnical participants in the development project.

For better elaboration, here is an example:

Benefits Of BDD Automation

Following are the reasons why most software development teams choose BDD as their preferred testing methodology.

1- Excellent Results

Through the BDD approach, developers have resulted in software design that syncs with the exact business owner’s requirements, leading to suitable solutions.

2- Flexibility

BDD in software development projects allows excellent flexibility in new design integrations. Also, it makes the software architecture simpler and easier to manage. It makes the system so flexible that you can quickly adjust to new requirements without disturbing the proprietary stability and work balance.

3- Efficient Collaboration

The majority of the project development teams adopt BDD for efficient communication throughout the project. Excellent communication between the team makes feedback and tracking updates simple.

4- User Satisfaction

To improve business appraisal and help to gather more customers requires BDD to software satisfy user’s needs. Moreover, user-focused development boosts customer loyalty and is necessary for brand reputation.

5- Deep Understanding

BDD ensures that both tech-oriented and nontechnical team members also have insight into the project’s progression. To a great extent, common language makes it possible to involve everyone.

6- A Living Documentation

BDD is a real example of an all-time usable description of the current system behavior. The results drawn from the system are the most accessible project guidelines for the developers involved. Furthermore, it validates the system before regulatory or third-party changes.

7- Instant Iterations

BDD makes it easier for the team to work in rapid repetitions. At the same time, allowing the team to continuously break down users’ problems into several elements for fast development.

Principles Of BDD:

Here are some of the basic principles of BDD (behavior-driven development):

Enough is Enough

The principles of BDD enough is enough, include advanced planning, analysis, and design that have diminishing returns. We must not do less than what is essential to start but put more than that when it’s time to finish.

Delivering value to “Stakeholders”

For instance, if any team member is doing something that does not deliver value or increases your skills or ability to deliver outcomes. Then that specific member should quit that and do something different.

Everything is behavior

Either at the level of code application or about testing and beyond, the team should use the same ideas and language to describe the behavior at any level.

These principles are broken down into three main things, which are:

Warping Up:

At the end of the day, BDD (Behavior Driven Development) is about streamlining the entire software development process and delivering the required results. And the answer to what is BDD? It is not only a mere toolset, but it is a mindset.

BDD teaches business analysts, testers, and developers effective ways to discover the requirements. Moreover, it can also help the developers to write higher quality code and ensure maintenance.

However, one thing you need to remember is that when dealing with BDD, follow only the best practices. This will undoubtedly allow you to enhance your expertise in this intelligent, agile software development methodology approach.

The Basics Of Support Driven Development

In this digitally thriving world, there are a lot of concepts lingering in mobile application development. And you must have heard of these as well. Particularly the most infamous terms – “Support Driven Development”, “Test-Driven Development”, and “Acceptance Test-Driven Development”. TDD and ATDD all are the same sides of different coins. Yes, these processes each have their perks and benefits and affect the development cycles. Thus, today we will share a brief on each so that our readers and viewers can all have them clarified, and understand how important a role each of them plays separately. And, for different scenarios.

Creators Are Also The Builders In Support Driven Development

“Injecting humility, accountability, and responsibility into the development process by making sure the creators are also the supporters. If I’m going to build this, how does it affect me later when I have to support the user?” – Kevin Hale
Well, this is a bit complicated, right? In a simple view, you can say that Support Driven Development is the procedure that helps you develop a product associated with the customer’s needs as you adapt your project at every stage as per the recommendations and demands of the users. To get an indistinct picture, have a look at some of the benefits that Support Driven Development brings to your project or product building.

Advantages Of Support Driven Development

The benefits of Support Driven Development are numerous. Customer services, customer retention, and customer care – all may be different terms but revolve around the same theory. Businesses, however big or small, must follow excellence in customer services to mark their target audience. If you are in business or have a company running under you, the question arises that why your reputation is based on your customer services? Every business does not have a huge structure or a large set of employees working underneath to cater to their customers’ needs. One of the few ways small businesses can surpass their competitors is by delivering outstanding customer service. Thus, here is a shortlist to understand the benefits of support-driven development. These are:

Speed Up The Product Knowledge

There is nothing that can throw a reasonable amount of light on the strengths as well as weaknesses of a product or service better than a user or a customer. The reason is that they are people who use that product and analyze it. They use it and can recommend or complain about it.

Helps To Improve The Product Quality

The collaboration between the product’s maker and the user is very essential. Support Driven Development also suggests this kind of collaboration. It helps the developer to become active and involved to a bigger level in the product. It is normal human behavior that when a person must support his/her work, he tries to give it his/her best shot. And, as soon as they know they are lacking somewhere, they find the way around to fix those issues. These two factors together make the development and developer more active and involved in the product.

Manage Support Structure

Developers with technical knowledge convey new ideas to automate support procedures to the best workable level. This improves the quality of support provided to customers and expands the ways of support structure as well.

You Get To Meet Your Happy Customers

With a continuously improving product, immense attention, and quality support, the support-driven development brings in happy customers. Once your customers realize the effort and how they feel about the user experience – your overall business ratings improve. Thus, to attain happy customers, focus on your development and release cycles carefully.

Test-Driven Development – The Basics

Kent Beck is the mind behind the implementation of Test-Driven Development. In simple terms, Test-driven development is a software development procedure depending on the software requirements being transformed to test cases. It is determined before the software is completely developed and follows all software development by testing the software recurrently adjacent to all types of test cases. The TDD procedure contains the following stages:

  • Founded on the stated requirements, an automated test case is written by the developer.
  • Next, the written tests are executed.
  • They might fail as they are industrialized before the development of a concrete characteristic.
  • The development lineup re-factors the code aimed at the test to pass effectively.

Benefits Of Test-Driven Development

Below we have listed some noteworthy benefits of TDD, these are:

  • Supports to reduce the extent of time compulsory for rework
  • Helps discover bugs or faults swiftly
  • Assist in getting a quicker feedback
  • Boosts the development of great designs
  • Improves the output of the programmer
  • Let any team member lead work on the code in the nonappearance of a particular team member.
  • Inspires knowledge division and teamwork
  • Adds in self-assurance so that the programmer can modify the huge architecture of an application
  • Outcomes in the formation of wide-ranging code that is adaptable and affluent to sustain

Acceptance Test-Driven Development – ATDD

During Acceptance Test-Driven Development (ATDD) method, a specific acceptance test is inscribed from the operator’s viewpoint. It primarily emphasizes sustaining the functional performance of the system. This method lets the developers know if the code is working according to the user’s expectations. ATDD is identical to Behavioral-Driven Development. Yet, a significant difference between them is that the BDD centers further on the performance of the feature, while the ATDD essences on seizing the precise requirements. The succeeding is a few of the key ways in ATDD:

  • Scrutinizing and deliberating the real-world circumstances
  • Determining the acceptance standards for those test setups
  • Systematizing the acceptance test scenarios
  • Concentrating on the development of those requirement situations

Advantages Of ATDD

This method improves the alliance between the developers, QAs, and the users. The communal focus is on classifying the acceptance standards. And the advantages are:

  • Requirements are visibly analyzed without vagueness
  • Boosts collaboration between cross-team associates
  • The acceptance test obliges as a standard for the whole development procedure
