Behavior Driven Development (BDD): Introduction
Behavior Driven Development (BDD) is an agile software development methodology that focuses on the use of software tools to achieve better results. BDD is a derivative of Test Driven Development (TDD), which is a process-oriented approach to software development. The main difference between BDD and TDD is that BDD focuses on the behavior of the system, rather than the implementation of the code itself. BDD encourages collaboration between developers, testers, and other stakeholders to ensure that the system behaves as expected.
BDD – Test Driven Development
Test Driven Development (TDD) is a process-oriented approach to software development. It is an iterative process of writing automated tests before the code is written. In TDD, the tests are written before the code, and the tests are used to drive the design and development of the software. Each test describes a small piece of functionality that should be implemented. Once the tests are written, the developer can begin writing the code to implement that functionality.
TDD is an effective way to ensure that the software is built to meet the requirements and that the code is of good quality. TDD also helps to reduce the risk of bugs and other problems in the software.
BDD – TDD in a BDD Way
TDD can be used in a BDD way by taking the tests and making them more readable and understandable. This is done by adding more context to the tests. The tests should be written in a way that describes the behavior of the system and not just the implementation of the code.
For example, instead of writing a test that checks the value of a variable, you could write a test that checks the behavior of the system when a certain action is taken. This will make the tests more readable and understandable, and it will also help to ensure that the system behaves as expected.
BDD – Specifications by Example
Specifications by Example (SBE) is a process for writing executable specifications. It is a way to describe the expected behavior of a system in an executable format. The executable specifications are written in a language such as Gherkin, which is a language used to describe the behavior of a system.
The executable specifications are written in a way that is readable and understandable by all stakeholders, including developers, testers, and other stakeholders. The executable specifications are used to drive the development process and ensure that the system behaves as expected.
BDD – Tools
There are a number of tools available to help with BDD. These tools include Cucumber, Gherkin, and SpecFlow. These tools are used to write executable specifications in a language such as Gherkin. They also provide features such as reporting and code generation to help automate the process of writing the executable specifications.
BDD – Cucumber
Cucumber is a tool for writing executable specifications. It is written in the Ruby programming language and is used to describe the behavior of a system. Cucumber is used to write executable specifications in a language called Gherkin, which is a language used to describe the behavior of a system.
Cucumber provides features such as reporting and code generation to help automate the process of writing the executable specifications. It also provides support for integration with other tools such as Selenium Web Driver and Jenkins.
BDD – Gherkin
Gherkin is a language used to describe the behavior of a system. It is used by tools such as Cucumber and SpecFlow to write executable specifications. Gherkin is a business-readable, domain-specific language used to describe the behavior of a system.
Gherkin is written in a human-readable format and is used to describe the behavior of a system. It is used to write executable specifications in a language such as Cucumber or SpecFlow.
BDD – SpecFlow
SpecFlow is a tool for writing executable specifications. It is written in the .NET programming language and is used to describe the behavior of a system. SpecFlow is used to write executable specifications in a language called Gherkin, which is a language used to describe the behavior of a system.
SpecFlow provides features such as reporting and code generation to help automate the process of writing the executable specifications. It also provides support for integration with other tools such as Selenium Web Driver and Jenkins.
BDD – Advantages and Disadvantages
Behavior Driven Development has a number of advantages. It helps to ensure that the system behaves as expected and that the code is of good quality. BDD also encourages collaboration between developers, testers, and other stakeholders.
However, BDD also has some disadvantages. Writing executable specifications can be time-consuming, and it can be difficult to keep up with the ever-changing requirements of the system.
BDD – Features
Behavior Driven Development has a number of features that make it an attractive option for software development. BDD encourages collaboration between developers, testers, and other stakeholders. It also helps to ensure that the system behaves as expected and that the code is of good quality. BDD also helps to reduce the risk of bugs and other problems in the software.
Final Words
Behavior Driven Development is an agile software development methodology that focuses on the use of software tools to achieve better results. BDD is a derivative of Test Driven Development, and it focuses on the behavior of the system, rather than the implementation of the code. BDD encourages collaboration between developers, testers, and other stakeholders to ensure that the system behaves as expected. BDD also helps to reduce the risk of bugs and other problems in the software.
