Behavior-Driven Development (BDD) is a software development technique where the requirements are written as stories in plain language, and the test cases are derived from these stories. This approach makes it easier for stakeholders to understand the requirements and to verify that the software meets their needs.
The Benefits of BDD
BDD offers a number of benefits over traditional software development approaches, including:
-
Improved communication: BDD helps to improve communication between developers, testers, and stakeholders by using a common language to describe the requirements.
-
Reduced risk: BDD helps to reduce the risk of defects by ensuring that the requirements are clear and that the software is tested against these requirements.
-
Increased agility: BDD makes it easier to change the requirements as the project progresses, as the tests are derived from the requirements and can be easily updated.
BDD in Practice
BDD is typically used in conjunction with agile software development methodologies, such as Scrum or Kanban. The BDD process typically involves the following steps:

Behavior-Driven Development (BDD).
Provides a comprehensive guide to BDD, covering its principles, practices, and integration into the software development lifecycle. It's suitable for gaining a broad understanding and deepening knowledge, offering practical examples and insights into incorporating BDD with Agile and DevOps. The second edition includes updated techniques and valuable reference for professionals.
Authored by the creator of Cucumber, this book practical guide to using Cucumber for BDD. It's excellent for understanding how to translate BDD principles into executable specifications using the Gherkin language and automating tests. While published in 2012, its fundamental concepts and practical examples remain highly relevant for testers and developers.
Focuses on the crucial 'discovery' phase of BDD, emphasizing collaborative techniques like example mapping to explore and define behavior. It's a practical guide that complements more technical books by focusing on the upfront communication and understanding needed for successful BDD. It's suitable for the whole team involved in specification and delivery.
As the second book in 'The BDD Books' series, this book delves into the 'formulation' phase, specifically how to document examples using the Given/When/Then structure (Gherkin). It provides practical guidance on writing clear and effective executable specifications. It's a great follow-up to 'Discovery' and is essential for those writing Gherkin features.
Provides a practical guide to BDD, focusing on the challenges and pitfalls of implementing BDD in software development projects. It is particularly useful for developers who have some experience with BDD but want to learn how to apply it effectively.
While not strictly a BDD book, this classic text on Test-Driven Development (TDD) is highly relevant as BDD evolved from TDD. It provides a deep understanding of driving development with tests and the principles of emergent design. is valuable for developers looking to solidify their understanding of the technical practices that underpin BDD.
Provides a broad overview of Agile development practices, including concepts that are foundational to BDD, such as collaborative planning and testing. While not solely focused on BDD, it provides essential context and understanding of the Agile environment in which BDD thrives. It's a valuable resource for anyone wanting to understand the broader picture of Agile software development.
Writing clean and maintainable code is essential for the success of BDD automation. provides timeless principles and practices for writing clean code, which directly supports the sustainability of a BDD test suite. It's a must-read for any developer involved in BDD.
A more concise version of 'Agile Testing,' this book provides a brief introduction to key agile testing practices that are relevant to BDD. It's a good starting point for those new to agile testing and its relationship with BDD.
Practical guide to working with user stories, which are often the starting point for defining behaviors in BDD. It provides valuable techniques for writing effective user stories and breaking them down, which is directly applicable to the discovery and formulation phases of BDD.
Practical guide to BDD, focusing on using the Behave framework to implement BDD in software development projects. It is particularly useful for Python developers who want to learn how to use Behave to write and execute BDD tests.
