Getting Started with JBehave

JBehave is a renowned framework tailored for Behaviour-Driven Development (BDD). BDD is a refined version of test-driven development (TDD) and acceptance-test driven design. The primary objective of BDD is to make these practices more intuitive and accessible to both novices and seasoned professionals.

JBehave emphasizes behavior over testing. It's not just a testing tool but a design philosophy. This shift in perspective from testing to behavior makes it a standout choice for many developers.

Core Concepts of JBehave

  • Story: A story in JBehave represents an executable increment of business functionality. It consists of one or more scenarios.
  • Scenarios: These are concrete examples of how the system behaves. They provide a clear picture of the expected behavior of the system under different conditions.
  • Steps: Steps are the actual behaviors and are defined using the classic BDD keywords: Given, When, and Then.

Being a pure Java framework, JBehave is built upon the foundation of JUnit.

JBehave vs. Cucumber: A Comparative Analysis

While both JBehave and Cucumber serve the purpose of BDD, they have distinct characteristics:

  • Language Base: JBehave is purely Java-based, while Cucumber originates from Ruby. For Java projects, Cucumber-JVM, a stable Java wrapper for Cucumber, can be used. However, since Cucumber inherently uses Ruby, there might be occasional mismatches.
  • Reporting: Cucumber boasts visually appealing reporting. In contrast, JBehave's HTML report might seem a tad traditional. But for a Java project, JBehave is often the preferred choice, especially if reporting isn't the primary concern.

Integrating JBehave with Selenium

For those familiar with Cucumber, integrating JBehave with Selenium will be straightforward. In BDD, tests are typically written in Gherkin syntax. Each step in Gherkin corresponds to a step definition, which contains the core logic.

To begin with JBehave and Selenium:

  1. IDE Setup: Ensure your IDE recognizes the .story file extension. For IntelliJ users, the "JBehave Support" plugin is recommended.
  2. Dependencies: Add JBehave and Selenium dependencies to your pom.xml.
  3. Story Files: Create a folder named "resources" under "src" and inside the "test" folder. This is where you'll place your .story files.
  4. Step Definitions: Link all the Given, When, and Then statements from the story file to their respective step definitions. For instance, if your story file is named "Demo.story", the corresponding step definition class should ideally be "DemoSteps.java".
  5. Runner: Just like Cucumber requires a runner defined using "cucumber.options", JBehave needs a similar setup. The runner will help in parsing the .story files and executing them.

Once everything is set up, you can execute your story using the command: mvn clean test.

FAQs

  1. What is JBehave?
    JBehave is a Java-based framework for Behaviour-Driven Development (BDD).
  2. How is JBehave different from Cucumber?
    JBehave is purely Java-based, while Cucumber is based on Ruby. However, both are powerful BDD tools.
  3. Can I use JBehave with Selenium?
    Yes, JBehave can be seamlessly integrated with Selenium for writing tests in Gherkin syntax.
  4. How do I run a JBehave story?
    After setting up the story, step definitions, and runner, you can execute your story using the command: mvn clean test.
