400 Cucumber Interview Questions with Answers 2026

Master Cucumber BDD with 2026 Interview-Ready Practice Questions and Real-World Scenarios.

Cucumber BDD Interview Practice Questions are designed to bridge the gap between basic syntax and professional-grade framework engineering, ensuring you don’t just memorize definitions but actually master the logic behind scalable automation. I have meticulously crafted this course to cover everything from Gherkin fundamentals and Scenario Outlines to complex dependency injection with PicoContainer and CI/CD integration using Jenkins and REST Assured. Whether you are a beginner preparing for your first QA role or a senior automation engineer tackling architectural interview questions, I provide detailed explanations for every single option to help you understand the "why" behind every best practice. By focusing on real-world pain points like parallel execution, custom parameter types, and handling JWT/OAuth in API tests, I’ve ensured this question bank mirrors the actual challenges you’ll face in high-stakes technical interviews and enterprise projects.

Exam Domains & Sample Topics

• Section 1: Cucumber Fundamentals & BDD Concepts (Gherkin Syntax, Hooks, Tags, Background, Feature Files)

• Section 2: Framework Design & Integration (Selenium, JUnit/TestNG, POM, Maven, Dependency Injection)

• Section 3: Advanced Concepts & Best Practices (Data Tables, Regex, Parallel Execution, Custom Reporting)

• Section 4: API & DevOps Integration (REST Assured, Jenkins, Docker, Cloud Grids, CI/CD Pipelines)

• Section 5: Real-Time Scenarios & Security (OAuth/JWT, Mocking, Database Validation, Debugging Strategies)

Sample Practice Questions

• Question 1: Which of the following statements accurately describes the behavior and scope of a Background in a Cucumber feature file?

  • A) It runs once before the entire Feature file starts.

  • B) It runs after every Scenario to reset the test data.

  • C) It runs before every Scenario, including every row in a Scenario Outline.

  • D) It is used only for defining global variables and cannot contain executable steps.

  • E) It executes only before the first Scenario of a Feature file.

  • F) It is a replacement for @Before hooks in the Step Definition file.

  • Correct Answer: C

  • Overall Explanation: The Background keyword allows you to add context to the scenarios in a single feature. it is executed before each scenario but after any @Before hooks.

  • Option-Specific Explanations:

    • A is incorrect: This describes a "Before-All" setup; Background runs before every scenario.

    • B is incorrect: Background is for setup, not teardown (After hooks handle resets).

    • C is correct: It executes before every individual scenario and every iteration of a Scenario Outline.

    • D is incorrect: Background contains standard Gherkin steps (Given/When/Then).

    • E is incorrect: It does not stop after the first scenario; it repeats for all.

    • F is incorrect: Background is a Gherkin-level construct; @Before is a code-level Hook. They are often used together.

• Question 2: When integrating Cucumber with TestNG for parallel execution at the "Scenario" level, what is the primary requirement?

  • A) Set parallel = true in the @CucumberOptions annotation.

  • B) Set thread-count to 1 in the testng.xml file.

  • C) Override the scenarios() method in the Runner class and use the @DataProvider(parallel = true) annotation.

  • D) Use the Background keyword to split scenarios into different threads.

  • E) Scenario-level parallel execution is not supported in Cucumber-TestNG.

  • F) You must use the maven-surefire-plugin with the forkCount set to zero.

  • Correct Answer: C

  • Overall Explanation: To achieve scenario-level parallelism in TestNG, you must interact with the DataProvider that supplies the scenarios to the executor.

  • Option-Specific Explanations:

    • A is incorrect: There is no parallel attribute inside the @CucumberOptions annotation.

    • B is incorrect: Setting thread-count to 1 explicitly forces sequential execution.

    • C is correct: Overriding the scenarios() method and marking the provider as parallel is the standard TestNG approach.

    • D is incorrect: Background is for step reusability, not execution threading.

    • E is incorrect: It is supported and is a very common interview question.

    • F is incorrect: Setting forkCount to zero disables JVM forking entirely.

• Question 3: How does Cucumber handle "Dependency Injection" using PicoContainer?

  • A) It requires a public static void main method to initialize classes.

  • B) You must manually instantiate the Step Definition classes in a Base class.

  • C) It automatically shares state by injecting the same instance of a class into the constructors of multiple Step Definition classes.

  • D) It uses the @Autowired annotation from the Spring Framework.

  • E) It creates a new instance of every Step Definition class for every step executed.

  • F) It requires all variables to be declared as static to share data between steps.

  • Correct Answer: C

  • Overall Explanation: PicoContainer is a lightweight DI library that helps share state (like WebDriver or test data) between different Step Definition files without using static variables.

  • Option-Specific Explanations:

    • A is incorrect: Cucumber manages the lifecycle; a main method is not used for DI setup.

    • B is incorrect: Manual instantiation leads to tight coupling and is exactly what DI avoids.

    • C is correct: PicoContainer looks at constructors and "injects" shared objects automatically.

    • D is incorrect: Spring uses @Autowired, but PicoContainer works via constructor injection without annotations.

    • E is incorrect: Instances are shared across the life of a single scenario, not recreated per step.

    • F is incorrect: Using static variables is a "code smell" and a bad practice in parallel testing.
