Questions on Behavior-Driven Development (BDD) and Gherkin Syntax

These questions are designed to assess a candidate's understanding and experience with Behavior-Driven Development and Gherkin syntax, from basic concepts to practical application and collaboration.

Fundamental Concepts​

  1. What is Behavior-Driven Development (BDD), and how does it differ from Test-Driven Development (TDD)?

    • Aim: To assess the candidate's understanding of BDD principles and its focus on collaboration and communication.

  2. Can you explain what Gherkin is and why it's used in BDD?

    • Aim: To check knowledge about Gherkin’s domain-specific language and its role in making specifications understandable to all stakeholders.

  3. Describe the structure of a Gherkin file. What elements does it contain?

    • Aim: To test familiarity with Gherkin syntax elements like Feature, Scenario, Given, When, Then, And, But.

Practical Application​

  1. How do you write a Gherkin scenario for a new feature? Provide an example.

    • Aim: To evaluate the ability to apply Gherkin syntax to real-world examples.

  2. What tools do you use for implementing BDD in projects, and how do they work with Gherkin?

    • Aim: To understand experience with BDD frameworks like Cucumber and how they integrate with Gherkin syntax for testing.

  3. How do you handle parameterization in Gherkin to test different input values?

    • Aim: To assess knowledge on making tests more efficient and comprehensive by using Examples or Scenario Outline in Gherkin.

Collaboration and Communication​

  1. How does BDD facilitate communication between technical and non-technical team members?

    • Aim: To look for insights into how BDD fosters better understanding and collaboration among team members.

  2. Can you describe a challenge you faced while implementing BDD and how you overcame it?

    • Aim: To evaluate problem-solving skills and the ability to navigate the hurdles of adopting BDD practices.

Advanced Understanding​

  1. How do you organize large numbers of Gherkin scenarios to keep them manageable and understandable?

    • Aim: To test strategies for maintaining a clean and organized suite of BDD tests, such as tagging and structuring features.

  2. Describe how you would integrate automated testing with BDD in a continuous integration/continuous deployment (CI/CD) pipeline.

    • Aim: To assess understanding of modern development practices and how BDD fits into automated build and deployment processes.
