Question 1

How do I set up Cucumber JVM with Gradle?

Accepted Answer

Use the official starter project for Gradle linked in the README, which provides a basic configuration. Add dependencies in build.gradle, define feature files in src/test/resources, and write step definitions in Java to get started quickly.

Question 2

Cucumber JVM vs JUnit: which is better for BDD?

Accepted Answer

Cucumber JVM is designed for BDD with plain-language tests in Gherkin, ideal for collaboration. JUnit is a unit testing framework better for isolated code tests; use Cucumber for acceptance testing and JUnit for lower-level validation, often together in projects.

Question 3

What are best practices for writing Gherkin scenarios in Cucumber JVM?

Accepted Answer

Keep scenarios concise and focused on behavior, use declarative language, avoid technical details, and organize features with tags. Reference the Cucumber documentation linked in the README for guidelines on Given-When-Then structure and data tables.

Question 4

How do I handle data tables in Cucumber JVM steps?

Accepted Answer

Define step methods in Java that accept DataTable parameters, then use converters or iterate rows to map data. Cucumber provides built-in support for lists and maps, but custom parsing may be needed for complex structures.

Question 5

Can Cucumber JVM be used for integration testing in microservices?

Accepted Answer

Yes, it's suitable for integration testing by writing Gherkin scenarios that describe service interactions. However, set up step definitions to call APIs and manage test data, and consider mocking or stubbing for dependencies to isolate tests.

Question 6

Is there support for parallel test execution in Cucumber JVM?

Accepted Answer

Parallel execution is possible through build tools like Maven or Gradle plugins, or by configuring JUnit runners. However, it may require careful management of shared state and resources to avoid flaky tests.
