📄️ Introduction to Cucumber
Cucumber is a Behavior Driven Development (BDD) framework that helps teams write tests in a human‑readable format while still executing them as automated tests.
📄️ What is BDD (Behavior Driven Development)?
Behavior Driven Development (BDD) is a development and testing approach that focuses on system behavior from the user’s perspective, rather than technical implementation details.
📄️ Cucumber Architecture Overview
Understanding Cucumber architecture is critical before writing feature files or step definitions.
📄️ Gherkin Language Basics
Gherkin is a domain-specific language used by Cucumber to describe application behavior in a human-readable format.
📄️ Writing Good Gherkin Scenarios
Good Gherkin is the heart of successful BDD.
📄️ Background Keyword
The Background keyword in Gherkin is used to define common preconditions that apply to all scenarios within a feature file.
📄️ Scenario vs Scenario Outline
Understanding the difference between Scenario and Scenario Outline is critical for writing clean, maintainable BDD tests.
📄️ Data Tables & Examples
Cucumber provides Data Tables and Examples to handle data-driven scenarios.
📄️ Feature File Design from User Stories
Good Cucumber feature files start from user stories, not from automation steps.
📄️ Step Definition Basics
Step definitions are where Gherkin steps are mapped to executable automation code.
📄️ Cucumber Expressions vs Regular Expressions
Cucumber supports two ways to match Gherkin steps to code:
📄️ Parameterization & Data Mapping in Step Definitions
Parameterization allows Cucumber steps to accept dynamic data instead of hardcoded values.
📄️ Glue Code & Package Structure
Glue code tells Cucumber where to find step definitions, hooks, and supporting classes.
📄️ Shared State & Scenario Context
In real Cucumber frameworks, steps often need to share data.
📄️ Runner Class & Cucumber Options
The Runner Class is the control center for executing Cucumber tests.
📄️ Tags & Tag Expressions
Tags in Cucumber allow you to control which scenarios are executed without changing feature files.
📄️ Hooks (Before, After, Order, Best Practices)
Hooks in Cucumber allow you to execute code before and after scenarios or steps.
📄️ Dry Run & Undefined Steps
Dry Run is one of the most misunderstood yet powerful features in Cucumber.
📄️ Reporting & Plugins
Reporting is a critical part of Cucumber automation.
📄️ Cucumber with TestNG Integration
Cucumber by itself focuses on BDD and scenario execution, but it relies on a test framework like TestNG for advanced execution control.
📄️ Parallel Execution in Cucumber
Parallel execution is essential for reducing execution time in large automation suites.
📄️ Cucumber with Selenium (UI Automation Patterns)
When using Cucumber for UI automation, how you structure Selenium code matters more than the tools themselves.
📄️ Cucumber with API Automation (Rest Assured Patterns)
Using Cucumber for API automation requires a behavior-first approach with clean separation between
📄️ Error Handling, Retries & Flaky Test Control
Flaky tests reduce trust in automation. This section explains how to handle errors, apply retries responsibly, and design stable Cucumber frameworks—especially for CI/CD.
📄️ Cucumber in CI/CD Pipelines
Integrating Cucumber into CI/CD pipelines ensures fast feedback, consistent quality, and confidence in releases.
📄️ Common Cucumber Framework Anti-Patterns
Anti-patterns are practices that seem to work initially but cause long-term pain.
