Steps to Run Cucumber with JUnit 5:

1. Set Up Your Project:

a. Create a new Maven or Gradle project. b. Add the necessary dependencies for Cucumber, JUnit 5, and any other relevant libraries.

2. Write Feature Files:

a. Create feature files in Gherkin syntax, defining scenarios and steps. b. Use Cucumber expressions to link steps with the corresponding methods in step definition classes.

3. Implement Step Definitions:

a. Create step definition classes to translate Gherkin steps into executable code. b. Use annotations from the cucumber.api.java package to map steps to methods.

4. Configure JUnit 5 Runner:

a. Create a JUnit 5 test class. b. Use the @RunWith annotation to specify the Cucumber runner: @RunWith(Cucumber.class). c. Use the @CucumberOptions annotation to provide configuration details.

5. Run Your Cucumber Tests:

a. Execute the JUnit 5 test class. b. Observe Cucumber executing the scenarios defined in your feature files.

FAQs about Running Cucumber with JUnit 5:

1. Can I Run Cucumber Tests Without JUnit?

While Cucumber is often associated with JUnit, it supports other test runners such as TestNG. However, JUnit 5 is a popular and well-supported choice.

2. How Do I Handle Test Context and State in Cucumber with JUnit 5?

Use dependency injection provided by Cucumber-JVM to share state between step definition classes. Utilize hooks for setup and teardown.

3. Can I Integrate Cucumber with Spring Boot and JUnit 5?

Yes, Cucumber integrates seamlessly with Spring Boot. Use the @SpringBootTest annotation in your step definition classes for Spring Boot integration.

4. Are Parallel Executions Supported with Cucumber and JUnit 5?

Yes, JUnit 5 supports parallel execution. Use the @Execution annotation along with the CONCURRENT mode to enable parallel test execution.

5. How Do I Customize Test Reports in Cucumber with JUnit 5?

Use plugins like cucumber-reporting or cucumber-html-report to generate customized HTML reports. Configure the plugins in the @CucumberOptions annotation.

6. Can I Run Cucumber Tests from the Command Line with JUnit 5?

Yes, use the mvn test command to run your JUnit 5 Cucumber tests from the command line.

7. Can I Integrate Cucumber with JUnit 5 in IntelliJ IDEA?

Yes, IntelliJ IDEA provides excellent support for Cucumber and JUnit 5. Ensure you have the necessary plugins installed, and IntelliJ should recognize and execute Cucumber features seamlessly.

8. How Can I Share State Between Different Step Definitions?

Cucumber-JVM provides a built-in dependency injection mechanism. You can use PicoContainer or Spring as the DI container to share state between step definition classes.

9. Are JUnit 5 Extensions Compatible with Cucumber?

Yes, JUnit 5 extensions can be used in conjunction with Cucumber. This allows you to further extend JUnit 5’s capabilities in the context of Cucumber tests.

10. Can I Use Cucumber with Parameterized Tests in JUnit 5?

Yes, Cucumber supports parameterized tests in JUnit 5. You can use scenario outline tables in feature files or leverage scenario outline examples to achieve parameterization.

11. How Do I Handle Asynchronous Operations in Cucumber with JUnit 5?

For asynchronous operations, you can use JUnit 5’s CompletableFuture support or Cucumber’s built-in DataTable to handle asynchronous data flow in your step definitions.

12. Is it Possible to Skip or Tag Specific Scenarios in Cucumber with JUnit 5?

Yes, you can use tags in feature files and then filter scenarios based on tags using the @Tag annotation in JUnit 5. This allows you to selectively run or skip specific scenarios.

13. What Should I Do If Cucumber Tests Fail Intermittently?

Intermittent failures may indicate issues with test data, environment setup, or asynchronous operations. Review your scenarios, step definitions, and ensure a stable testing environment.

14. Can I Integrate Cucumber with Continuous Integration (CI) Pipelines Using JUnit 5?

Absolutely, Cucumber tests integrated with JUnit 5 can be seamlessly incorporated into CI/CD pipelines. Use popular CI tools like Jenkins, Travis CI, or GitLab CI to automate your test executions.


By following these steps and leveraging external resources and FAQs, you can seamlessly integrate Cucumber with JUnit 5 for effective BDD test automation. The synergy between these two powerful tools empowers developers to create expressive and maintainable tests, fostering collaboration and enhancing the quality of software projects. As you embark on your BDD journey with Cucumber and JUnit 5, this guide equips you with the knowledge and resources needed for success.
