This method ensures that any system developed meets user requirements while being easy for everyone involved to use.

Your aim should be to provide your interviewer with the necessary details of your expertise in BDD while simultaneously showcasing your critical and creative thinking abilities. For the BDD framework, interview questions

This blog will offer various interview questions regarding BDD and advice on responding effectively.

Let’s get going!

1. What is BDD?

BDD is a collaboration between business and technical teams in an organization. It involves understanding user scenarios and application interaction and building a shared understanding of application behavior.

2. What are the three phases of BDD?

The three phases of BDD are discovery, formulation, and automation. The discovery phase involves discussing user stories and system Behavior, leading to agreed behavior.

The formulation phase creates concrete examples for development and automation, with documented examples and acceptance tests.

The automation phase involves coding based on documented examples and creating automation scenarios or tests.

3. What is living documentation in BDD?

Living documentation in BDD is a document that serves as a single source of truth for future changes or enhancements.

It is generated through the process of BDD and is updated as the project progresses.

4. What is Cucumber?

Cucumber is a tool that facilitates BDD in organizations. It allows organizations to automate documented examples and turn them into automated tests, helping to bridge the gap between teams and ensuring a successful application development process.

5. How can Cucumber help with BDD?

Cucumber can help with BDD by automating documented examples and turning them into automated tests.

This helps ensure that the application development process is successful and that all teams work towards a shared understanding of application behavior.

6. How does BDD help bridge the gap between teams?

BDD involves teams discussing user stories and system behavior, leading to agreed behavior.

This helps bridge the gap between business and technical teams by ensuring that everyone is on the same page about the application’s behavior and requirements.

7. What is the discovery phase of BDD?

The discovery phase of BDD involves teams discussing user stories and system behavior, leading to agreed behavior.

This phase helps ensure that everyone has a clear understanding of the application’s behavior and requirements before moving on to the next phase.

8. What is the formulation phase of BDD?

The formulation phase of BDD involves creating concrete examples for development and automation, with documented examples and acceptance tests.

This phase helps ensure that everyone has a clear understanding of how the application should behave in specific scenarios and that there is agreement on what constitutes acceptance.

9. What is the automation phase of BDD?

The automation phase of BDD involves coding based on documented examples, creating automation scenarios or tests.

This phase helps ensure that the application’s behavior is consistent with the agreed-upon requirements and that the code is reliable and maintainable.

10. What is the BDD process?

Behavior-Driven Development is a process in an organization that involves discussing and collaborating to determine the desired behavior of a user story.

BDD was born from Test Driven Development (TDD) and typically involves a user story as its starting point.

11. What is the purpose of the discovery phase in BDD?

The discovery phase in BDD involves discussing a user story between different teams to collaborate, explore, and ultimately determine the desired Behavior of the story.

12. What is an example of a BDD process?

An example of a BDD process is an online flight ticket booking application.

13. What is the next step after the discovery phase in BDD?

After the discovery phase, the team moves on to the next user story and holds a three-hour meeting to prepare and discuss the story for development.

14. What happens during the three amigos meeting in BDD?

During the three amigos meeting in BDD, the business person or product owner explains the user story and the development and testing teams collaborate on the desired Behavior.

15. What is the goal of the BDD workshop?

The BDD workshop aims to implement a well-defined system behavior by discussing different scenarios and use cases.

16. What are the different scenarios discussed in BDD?

In BDD, different scenarios and use cases may be discussed, such as blocking seats until the process is completed or cancelled, setting a time limit for the transaction, integrating an API for cancellations or rescheduled flights, and integrating a refund module for payment processing and booking failures.

17. What can be done with the scenarios created in the Behavior-Driven Development formulation phase?

BDD tools like cucumber can use the scenarios created in the formulation phase of Behavior-Driven Development to guide the development process and create automation tests.

18. What is the role of Gherkin in the formulation phase of Behavior-Driven Development?

Gherkin is a specification language used in the formulation phase of Behavior-Driven Development to create business-readable and executable scenarios from the agreed-upon examples.

BDD tools like Cucumber can understand this syntax and convert the examples into automation tests.

19. What is the purpose of the formulation phase in BDD?

The formulation phase in BDD aims to take the agreed-upon examples from the discovery phase and formulate them into business-readable and executable scenarios using specification language like Gherkin.

The outcome of this phase is a documented business-readable and executable scenario of system behavior that BDD tools like Cucumber can use.

20. What is the primary purpose of the BDD workflow?

The primary purpose of the BDD workflow is to ensure that the system behaves as required by the business owner and stakeholders.

This is achieved through a collaborative process that involves documentation, testing, and validation of user stories and examples.

The three amigos meeting involves the testing and development teams discussing user stories and examples with the business analyst.

This meeting aims to ensure that all stakeholders are on the same page regarding the system’s behavior requirements.

22. What happens in the code development phase?

In the code development phase, the development team executes the code and fixes any defects found during testing.

23. What is the traditional development process?

The traditional development process involves a product owner or business analyst meeting with stakeholders to discuss their needs.

This process typically involves a top-down approach to development, with little input from the end-users.

24. What is the benefit of using the BDD workflow?

The BDD workflow provides a collaborative and user-focused approach to development.

This approach helps to ensure that the system behaves as required by the business owner and end-users, leading to a more prosperous and efficient development process.

25. What is the sprint process in a BDD workflow?

The sprint process is a short time-boxed period where the team works to complete a set amount of work based on the number of user stories.

26. How does a BDD workflow begin?

A BDD workflow begins with a business owner expressing their requirements and changes in the product or application.

27. What is the purpose of the traditional development process?

The traditional development process involves gathering requirements, writing them in a requirement document, sharing it with the development and testing teams, and then executing tests.

28. What are the issues with the traditional development process?

The traditional development process has issues such as not involving the development and quality assurance teams during requirement gathering and user story creation.

Additionally, the development and testing teams work in silos, leading to a lack of shared understanding.

29. How does the Behavior-Driven development process address these issues?

The Behavior-Driven Development process addresses these issues by starting with a business owner or stakeholder meeting, where they discuss requirements, user stories, and system behavior examples.

These examples are documented using specification language like Gherkin, converting them into documentation.

30. What is the main advantage of the Behavior-Driven development process?

The Behavior-Driven Development (BDD) process allows stakeholders to create user stories and acceptance criteria, compared to traditional methods involving requirements, code creation, testing, automation, and bug fixation, with sprints for specific user stories.

31. How does the BDD process ensure collaboration, communication, and a shared understanding among allteams?

BDD involves development and quality assurance teams in requirement collection and user story building to promote teamwork, communication, and understanding.

Additional steps include a common source of truth, documented examples, and a single source of truth for all teams.
