Introduction to Behaviour Driven Development (BDD)
A lot of products and applications are launched every now and then these days. When launching a new digital project, some things must be taken care of for a smooth launch. Also, there has to be a connection between the launched product or an application and the prospective clienteles. On the other hand, more often or not a disconnection can arise between the following things which are listed below:
- The software creator is not thoughtful of the requirement of putting up the product or an application.
- The business is not able to define the desired outcomes
- The business’ consideration of the practical trials their requests may offer.
In all these situations, Behaviour Driven Development comes into play as it is able to take care of all these pain points. It can help accomplish all of the above circumstances. At the end of the day, it benefits a business and its technical side provide software that live up to business aims.
To understand it in a better way, let us understand Behaviour Driven Development in a comprehensive manner.
What is Behaviour Driven Development?
Put simply, BDD is a procedure intended to benefit the organization and the supply of software development ventures by refining communication between software creators and business specialists. By this means, BDD makes sure all growth projects continue concentrating on providing what the industry really wants while meeting all necessities of the consumer. Taking everything into account, Behaviour Driven Development (BDD) is a combination and an extension of Test Driven Development (TDD) and Acceptance Test Driven Development (ATDD). In BDD too we compose tests first and add application code. On the other hand, some differences that are visible are that the tests are written in basic eloquent English style grammar. These written tests are customer concentrated and are clarified as the behaviour of application. What is more, instances are used to shed light on necessities. All these alterations work for the necessity to have a language which can express, in a clear layout.
Necessity of Behaviour-driven development (BDD) framework
In this age of technology and software age, software development is frequently overloaded and a lot of software developers burn the midnight oil to reap benefits and get the desired results. As we all are aware of the simple fact that in software development, it is pretty common to make an effort in attaining aims with the addition of new features to products or applications.
This definitely wastes a lot of time for both engineers and industry specialists. Communication between both sides must be clear to prevent confusion in what the business really wants from its software. Also, at times, business specialists misjudge the skills of their technical line-up. Masked in poor judgment and difficulty, the finished application or a product is frequently technically well-designed. On the other hand, it misses the mark to meet the precise necessities of the business.
The idea needs to be transferred as it is, from business owners or client to software development. The most common mistake committed by the software teams is that while building a product or an application they start writing down the examples assigned to a single person. However, this is not enough. BDD involves diverse viewpoints and understandings so as to be well-organized. One of the essential notions behind BDD is that no solo individual has the complete solution to the problem. And this is where the collaboration of business person, software developer and tester comes into play. Insights from all three get all the angles covered in line with the software development. Behaviour-driven development (BDD) wishes to modify this as this is a collective procedure. And, BDD definitely addresses all these concerns.
On this note, let us delve into the features to get a clear picture of Behaviour-driven development (BDD).
Features of Behaviour-driven development (BDD) explained
BDD is gaining momentum day by day as it has a number of features to offer which help in offering myriad benefits. Let us discuss the features one by one, they are as follows:
- It definitely shifts the gears from thinking in tests to thinking in behaviour
- It also increases the association between the team members involved in software development. From testers and software developers to managers and business stakeholders, it enhances the communication between them displaying teamwork with enhanced profits.
- As the language used is universal, it can be easily understood and described.
- The main feature of it is that it is motivated by business value
- What is more, it lengthens Test Driven Development (TDD) and Acceptance Test Driven Development (ATDD) through the utilization of natural and universal language that non-technical members can decipher.
- With BDD frameworks available for instance Cucumber, it being an enabler, it turns as a link between business & technical Language, making things easier for everyone.
With so many features it changes the customer notion into something that truly provides umpteen profits to prospective buyers. All the team members can work as a team offering excellent communication, which is important to their success. In a nutshell, all these features which are present in Behaviour-driven development (BDD help in increasing TDD and ATDD.
And we finish off building a strong and verified product or an application in line with the business requirements. Every line of the creation code, arrangement or even design is openly associated with its specific consequence acquiring business objectives. This is the method BDD makes sure it continuously provides software that matters and is in line with the client requirements and brand essence. With so many features, BDD has its share of downsides too.
Downsides of BDD
Apparently, using examples variation to initiate circumstances so as to provide substantial software is the essence of BDD. However, in case of architecture obstruction, BDD possibly will not be as effective. The best instance for this case is offshore testing, apprehended back by organizational limits when people sit in different offices and are geographically far from one another. This is one such challenge, which is irrational as a lot of firms go for offshore testing. At times the social challenges also occur. This can be well understood with the help of an example. If by any chance business analysts and testers disconnect over an offshore resource by sending a specification then it does not give results and does not work. At times a software team involving a tester, developer and a business expert discussing the domain, problems and speaking about how they can resolve them, leads to all types of expectations and cut-offs.
No matter what is the platform, technology or language, the application or a product is delivered quite often. And, in order to attain success, it is necessary and is recommended also that every product or application needs to be updated and become accustomed to the client needs regularly. Keeping updated is the key as markets and technologies vary. As well, our understanding of business variations and we acquire new prospects on a daily basis. As a result, the way we provide software should echo this continuing procedure of variation.
So as to support the leap of variation, taking on circumstance-based test-driven development is not sufficient. It is recommended that we are able to do radical and quicker variations in the system under the modules. And, this is what BDD is all about. In BDD, we recognize so as to support the knack for systems to vary, so that we are able to securely make huge variations, in addition to the minor ones. Use BDD and adapt to the situation and in turn reap a lot of benefits in line with the brand essence, client needs and business demand.
In the world of software development, it is definitely an in-thing and is here to stay as it offers various features along with benefits.
