What is BDD Framework?

BDD Framework or Behavior-driven development is a process of development of agile software in software engineering. The process of BDD Frameworks focus on collaboration amidst developers, non-technical, business and QA participants in an application assignment. 

BDD Framework motivate the team to make use of firm examples and conversation to formalize a mutual understanding of the behaviour of an application. Test-Driven development forms the basis of behaviour-driven development. 

BDD Framework  combine the standard techniques and rules of text-driven development with ideologies from object-oriented design and analysis and domain-driven design to render management and application development teams with a shared procedure and shared tools to collaborate on application development. 

Behaviour-driven development is an ideology about the management of the development of an application from the perspective of technical insight as well as business interests. The BDD Framework does not use specialized tools to aid the process of development. However, these tools are basically developed to be used in projects concerning BDD Framework, but they can also be used as special tools which aid test-driven development. 

BDD Framework are mainly facilitated via the utilization of easy domain-specific language along with simple language to express the expected results and behaviour. It is considered as a useful tool when the problems of the business are much more complex. 

The focus of behaviour-driven development is basically on the initiation point of the procedure, the content which needs to be tested and how much content must be tested in a single round. Along with this, it lays emphasis on the results of the test and the reason for its failure (if the test fails). 

25 Popular BDD Frameworks You Need To Try

A tool that provides both business knowledge and technical insight is essential for any software developer. Behaviour-driven development is a software development approach designed to deduct the wasteful behaviour in application development. 

In this, the tests are written in the plain descriptive English language, making the code easy to understand for anyone. The tests are more users focused and explained as the behaviour of application rather than technical functionality. 

BDD Frameworks List

There are several BDD Framework tools out in the market proven to work effortlessly with different languages and structures. The popular ones are:

HipTest

HipTest

Looking for native BDD support, then HipTest is the one you need as it is the only continuous testing tool with this kind of support. It is capable of reusing steps of tests between multiple tests.  

This tool uses the shared business language to define criteria for acceptance. It can integrate with several other BDD tools. 

Cucumber

Cucumber

A free BDD tool which helps in developing easily understandable tests. Cucumber allows anyone from the stakeholder to the programmer to work on the problem statements to develop the best behaviour set. It mainly uses Ruby as the programming language; however, it supports other languages too.

EasyB

EasyB

EasyB is a tool with no IDE integration and uses stories as the verification units. The commands are mostly written in Groovy, therefore, the specifications can be written in English instead of Programmer-centric codes. This tool is useful in Unit testing. 

JDave

As this tool runs on JUnit, it can be smoothly used in Eclipse. Comparing to tools like cucumber which is a story runner framework, JDave is a specification engine that displays the behaviour of a class in each scenario. It is an easy tool to learn and apply. It is more of a developer-oriented framework.

Concordion

The Squish IDE tools support to develop, record and moreover debug Behaviour driven GUI tests.

Frank

Frank is a BDD tool which works based on cucumber. It allows the developer to write structured text tests and acceptance tests. These tests are executed against the developer’s iOS application.

NBehave

NBehave is a BDD framework that allows the shifting of vocabulary to behaviour-based on test-based.

Codeception

Codeception is a BDD tool, which provides rich assertions written in simple PHP DSL. All the tests are written in a descriptive manner which helps in easy understanding of what is being tested and the performance of the test.

Chakram

Chakram

This tool offers simple API testing. It helps in creating clear and comprehensive tests. It allows extension like HTTP assertions to be added to the testing.

Minitest

A small and amazingly fast framework meant for unit testing. It provides testing tools supporting TDD, BDD and benchmarking. This tool also offers a wide range of assertions that can enhance the readability and cleaning of the test.

LightBDD

This BDD tool helps in the development of easy to read test writing that can also be tracked easily during the execution of the test. The reports developed at the end are summarized in a user-friendly format which means anyone without a technical background can also understand.

Gauge

Gauge

Developed by ThoughtWorks, it is the latest open-source tool for test automation in Windows, Linux and Mac. The plus point of Gauge is its ability to create executable documentation. 

The tests (called specs) are written in simple language syntax using Ruby, Java and C#.

SpecsFor

SpecsFor

A flexible BDD tool that gives the developer plenty of room to write tests the way they want. It supports old-style plain text to latest BDD style specifications. 

What Are The Letdowns Of BDD Framework

Behavior-Driven Development is a software development approach where the team members discuss and examine the expected behaviour of the application. This is performed to construct system functionality that is expected and understandable by all. 

The test is user focus and created using concrete real-life examples. These tests are developed using natural language for easy readability by anyone. This tool is extremely useful while working with a cross-functioning team which involves technical as well as non-technical members. 

Though BDD weighs more into the advantageous side, it does come with some drawbacks. The drawbacks are as follows:

  • It is not easy for all

Though BDD framework commands are said to be easy for anyone to understand, there will be some communication issues with the technical and non-technical members. 

The non-technical teams will not have a deep understanding of technical features and their inputs will vary from the other. Also, getting the whole team on the same page is hard. The communication between the user and developer is also essential for developing BDD framework. 

Without the availability of the user, the developer will find it difficult to work past questions formed from user stories and ambiguities.

  • Requires opinion from everyone

In BDD framework features cannot be built without getting the opinions of everyone who are part of the software. For efficient BDD workflow, well-defined project requirements are needed. 

It also requires a dedicated development team to work closely with clients. This will help in faster communication and thorough involvement of everyone. It also requires information on how the developers expect people to use it and have an understanding of what purpose it should serve. 

  • BDD requires time

If you think about using the software only for a few months after releasing it to market, then BDD will not be of much use. It will weigh you down and definitely not meant for people in a hurry. 

The implementation of code requires significant time and effort. BDD is meant for those looking for lasting software and requires maintenance for many years. 

It is also beneficial for those using complex user interactions and multiple product features. 

  • Maintenance issue

BDD like any other automated functional testing framework requires maintenance. Most of the people are busy investing in new initiatives or project. 

They forget about keeping resources for the software they are already using. If proper maintenance is not provided, then automated testing will break. If this is not fixed further, then the software dysfunction will prosper.

  • Need for scripting skills

BDD requires scripting codes. Though these can be written in natural language using real-life examples, many developers find it difficult. 

This is mainly attributed to the use of manual testing for years. The team members will be required to learn coding or scripting skills.

  • Requires extension for smooth functioning sometime

Sometimes the difficulty is experienced in using the step definitions- Given/When/Then. To ease out the problem using IDE plugins such as VScode Cucumber will help in autocompleting the codes. 

  • Focuses only on values the software is expected to deliver

BDD framework helps in measuring the functionality and does not focus much on the quality of the work in progress. This is not beneficial unless the developer also carries out test-driven development (TDD). 

As the risk of building the right thing the wrong way is more. This is mainly due to the difficulty in maintaining or further extension of codes in future. BDD also faces issue in the availability of fewer supporting software.

Conclusions

BDD framework is a methodology rather than a toolset used in testing the behaviour of the application just the way it displays to a user. This software development approach shows how a feature works within well-defined scenarios of inputs, actions and outputs. 

BDD helps in eliminating a common situation that occurs between teams and developments like unsatisfied clients and overworked developers. BDD is an approach that encourages collaborations in projects mainly between developers, business team, project managers and QA. 

BDD framework provides room for development, testing and thinking of command codes from the business owner’s point of view. The test scenarios are created using detailed, real-life examples. Using plain text (ubiquitous language) as command code, BDD has outperformed TDD its predecessor. 

Many think BDD is same as TDD, which is not. In BDD, a clear understanding of what the system should do is derived from the perspective of customer and developers. 

While in TDD only the developers have an understanding of what the system should do. BDD is purely driven by business value and is user-focused. 

There are several BDD frameworks available in the market today. Cucumber, Specflow, Jbehave, EasyB, HipTestetc is a few to name. Cucumber is the most popular BDD framework. Most of these frameworks can code for many languages and few are available as open-source. These tools can also integrate with extensions.

BDD framework is a testing approach which cannot be seen as something that only matters to developers. BDD methodology requires the entire team to describe and understand the needs of the system from the beginning to the end and not just focus on code correction. Thus making the Behaviour-Driven Development framework an amazing approach to generate quality projects.
