Behavior-Driven Development (BDD) using Cucumber

Target Audience: Developers with basic programming knowledge and an interest in BDD practices.

Course Duration: 3 days (adjust based on desired depth and lab time)

Course Objectives:

• Understand the core principles of BDD and its benefits.

• Master Cucumber framework concepts and functionalities.

• Write clear and concise Gherkin feature files to define test scenarios.

• Implement step definitions in [Your Programming Language] to automate test steps.

• Integrate Cucumber with testing frameworks (e.g., JUnit/TestNG) for execution and reporting.

• Apply best practices for writing effective Cucumber BDD tests.

Day 1: Foundations of BDD and Cucumber

• Module 1: Introduction to BDD

  • Core principles of BDD (outside-in testing, collaboration)

  • Benefits of using BDD in software development

  • Comparison of traditional testing vs. BDD

• Module 2: Introduction to Cucumber

  • Introduction to Cucumber framework (features, step definitions, scenarios)

  • Benefits of using Cucumber for BDD testing

  • Introduction to Gherkin syntax (Given, When, Then, Examples)

Day 2: Mastering Gherkin and Step Definitions

• Module 3: Deep Dive into Gherkin

  • Advanced Gherkin features (Background, Scenario Outline)

  • Writing clear and concise scenarios with Given, When, Then keywords

  • Using Scenario Outlines and Examples for data-driven testing

• Module 4: Advanced Step Definitions

  • Advanced Gherkin features (Tags, Background, Scenario Outline)

  • Writing step definitions in [Your Programming Language] (using libraries and frameworks)

  • Best practices for writing maintainable and reusable step definitions

Day 3: Integration and Advanced Topics

• Module 5: Integration with Testing Frameworks

  • Integrating Cucumber with JUnit/TestNG for running features as tests

  • Executing tests from the command line or IDE

  • Generating test reports (HTML, JUnit XML)

• Module 6: Advanced Topics (Optional)

  • Choose relevant topics based on audience/time:

    • Dependency Injection with Cucumber (e.g., Spring with @StepScope)

    • Page Object Model (POM) design pattern for web UI testing

    • BDD with API testing (RESTful APIs)

    • Continuous Integration (CI) with Cucumber

  • Course Wrap-up: Resources, best practices, and Q&A
