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 TopicsSection 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 QuestionsQuestion 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: COverall 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: COverall 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: COverall 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.Welcome to the best practice exams to help you prepare for your Cucumber BDD Interview Practice Questions.You can retake the exams as many times as you wantThis is a huge original question bankYou get support from instructors if you have questionsEach question has a detailed explanationMobile-compatible with the Udemy app30-day money-back guarantee if you're not satisfiedI hope that by now you're convinced!
