Behavior Driven Development (BDD) is a software development process originated from test driven development. Lucid language and illustrative descriptions provide ease of creating better software with better understanding obtained by those involved in various development stages.
Behavior Driven Development Approach:
Generally, developers interpret the requirements received and they strive to meet them.
- BDD brings clarity in set of expectations for system functionality.
- Document created considers the developers and customers ability to understand.
- Illustrative document with mention of examples enables the approvals from customer for development.
- Assurance of focus on the actual requirements without twisted facts and assumptions.
- Documented examples become basis of acceptance testing.
- Test driven development when combined with Behavior driven development makes the specifications readable and easy to execute.
Development has gained speed and technology is changing faster than ever. Business Enterprises now-a-days adapt to the changing technology in order to implement the best possible solutions immediately.
During the times of increasing demand, the development team can excel if the errors are at minimal level. Time and money involved in coding and testing is limited with tight delivery schedules. Better processes, tools, and trained team create a joint impact on quality of development.
Top 5 Open Source BDD Tools:
Frameworks like Java, Python, and PHP have BDD Tools specifically designed to perform in support of these programming languages.
This open source Behavior Driven Development – BDD tool is widely used in writing automated acceptance testing documents for various web applications.
Cucumber is a software tool primarily implemented in Ruby and is not available for Java framework. Simple and non-technical method of test report writing empowers all stakeholders to contribute to the process. The acceptance is due to its ease to explain the reports to non-testers. Cucumber has over 30 million downloads for BDD tools.
Benefits of Cucumber:
- It supports programming languages such as Groovy, .NET, Python, PHP, Perl, Scala, and few other languages.
- Easy execution and reusable codes.
- Simple format of set of validations help in automation testing.
- Codes of this tool are usable along with other tools like Watir, Selenium etc.
- Capable of centrally storing the user requirement statement and the test conditions in single document.
- The Acceptance Test conditions are the behavior sets defined herein.
- The behavior set implementation and working exhibited in a way allows easy tracking.
- United working on a problem statement helps in deriving the most suitable behavior set.
Web based automation Developers, Testers and Management prefer Cucumber for its features and end-user experience in spite of being free of cost.
Fundamental requirements to use Cucumber:
- Ruby and Ruby development kit installation.
- Install Cucumber.
