400 Cucumber Interview Questions with Answers 2026

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)

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:

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?

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:

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?

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:

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.
