BDD stands for Behavior Driven Development, a software development method that focuses on application behavior. BDD promotes the use of natural language to express customer requirements and expectations. The platform creates test cases that focus on system behavior instead of just specific code.
BDD often starts by sketching out usage scenarios (user stories) to describe features from the user's perspective. These scripts are then used to create test cases and determine the desired behavior of the system through the use of tools such as Cucumber or Behave.
By focusing on behavior, BDD makes it easier for development and management teams to understand the necessary requirements. From there, create specific test cases and code during the software development process. This increases the engagement and efficiency of the development team, while ensuring that the final product reflects the customer's intent.
Behavior Driven Development (BDD) has its roots in a software development method called Test Driven Development (TDD). TDD was developed by Kent Beck in the 1990s and introduced in his book "Extreme Programming Explained" in 1999. TDD focuses on writing test cases before writing specific code and then writing code to overcome through these test cases.
BDD evolved from this approach and is considered an extension of TDD. The platform focuses on using natural language to describe the desired behavior of the system, thereby creating test cases.
The mainstream version was developed by Dan North in the early years of the 21st century and became popular in the Agile and software development communities. BDD was born to address understanding and expressing customer requirements and expectations more clearly and accurately.
The platform focuses on using natural language to describe the desired system features and behavior, thereby creating test cases. This technology ensures that the development team not only clearly understands the customer's requirements but is also capable of creating specific test cases to test the correctness of the features.
BDD also ensures interaction and consistency between stakeholders in the software development process, from the development team to the business team and customers. Technology creates consistency in the expression of requirements and expectations, thereby ensuring that the final software product reflects what the customer expects.
BDD helps focus on the desired behavior of the system from the user perspective and ensures that the developed feature reflects the customer's requirements.
The platform creates a common understanding among stakeholders in the software development process, from the development team to the business team and customers.
BDD script files can be used as living documents, helping to document and understand system functionality.
BDD creates test cases that can be used for automated testing, helping to ensure feature correctness.
Using BDD requires programmers to understand the process and how to write effective test cases. To access technology, programmers can review more information in the beginning.
To effectively implement BDD, organizations need a solid foundation, including support from organizational members and investment in development tools and processes.
Implementing BDD will impact the software development organization's existing workflows.
One of the first important features of BDD is the use of natural language to describe the desired behavior and modes of the system. This will bring many benefits such as:
Using natural language helps everyone, including non-technical team members such as sales and customers, easily understand and express system requirements and expectations clearly. clear.
By using natural language, everyone can actively participate in describing requirements and expectations, no longer constrained by technical skills or specialized knowledge.
Natural language descriptions are directly converted into test cases to test the correctness of the features. The utility ensures that requirements and expectations are properly understood and properly implemented during development.
The use of natural language often integrates well with the existing software development process, from automated testing to requirements management, the platform creates consistency and integration throughout the entire scenario development process. User Stories.
BDD focuses on creating test cases that focus on system behavior using tools like Cucumber or Behat. This provides many benefits, including:
Test automation saves time and effort compared to manual testing, while minimizing human errors during the testing process.
By creating automated test suites, BDD ensures the accuracy and correctness of the system's features, thereby ensuring that the system functions properly according to requirements and expectations.
Test cases that focus on system behavior can be easily integrated with automated test management tools such as Selenium, JUnit, or other testing tools. The platform makes the testing process more flexible and easy to manage.
Test automation helps create quick feedback from actual testing, thereby helping to detect and fix errors in a flexible and timely manner.
BDD creates consistency in the expression of requirements and expectations, a platform that ensures that the final software product reflects what the customer expects.
BDD generates rapid feedback using test cases that focus on system behavior. Users will receive many benefits from the platform such as:
BDD helps detect errors right from the development process, from writing user stories to automating testing. Technology detects and solves problems at an early stage, helping to reduce costs and time to fix errors later.
When errors are detected, the platform easily adapts and modifies usage scenarios and test cases to reflect changes. Technology supports the development process to become more flexible and faster.
Having quick feedback from testing helps increase engagement with customers and end users. This ensures that the system accurately reflects their requirements and expectations.
The rapid feedback process from testing helps create a continuous cycle of improvement, such as detecting errors, fixing, evaluating and improving. This activity helps software products become increasingly perfect.
By describing the desired system behavior through natural language and creating behavior-focused test cases, BDD delivers many important benefits:
BDD helps development teams better understand user requirements and expectations. This will create a software product that accurately reflects what users expect.
BDD promotes consistency in expressing requirements and expectations, ensuring that all members of the development team understand and agree on what needs to be developed.
Focusing on system behavior helps create platform-based, behavior-focused test cases that are automated and used to test the correctness and performance of the system.
Focusing on system behavior helps create rapid feedback from testing, technology changes, and product improvements more quickly and flexibly.
BDD combines the natural language used to describe requirements and expectations with the technical languages ​​used to write test cases and tests. This is how to build alignment between stakeholders in the software development process.
BDD encourages participation from all stakeholders, from the business team to the development team and end users. The goal is to ensure that everyone understands and accepts the requirements and expectations.
BDD attaches importance to writing test cases and automated testing to ensure feature accuracy. This factor helps the software development process become more continuous and flexible.
