A simple Angular 19 project demonstrating Behavior-Driven Development (BDD) using Cucumber.js and Playwright.

BDD Angular Demo with Cucumber.js and Playwright

This project is a demonstration of the integration of Behavior-Driven Development (BDD) practices with a modern Angular 19 application, utilizing Cucumber.js for BDD testing and Playwright for automated browser testing.

Technologies Used

• Angular 20: Modern web application framework
• TypeScript: Strongly-typed JavaScript for enhanced developer experience
• Cucumber.js: BDD test automation framework (see for more info)
• Playwright: Browser automation library for end-to-end testing
• TailwindCSS: Utility-first CSS framework for efficient styling

The Value of BDD and Living Documentation

Behavior-Driven Development bridges the gap between technical and non-technical stakeholders by:

1. Creating a common language: Gherkin syntax (Given-When-Then) provides readable test scenarios that business stakeholders can understand
2. Documenting specifications: Test scenarios serve as living documentation that evolves with the application
3. Validating acceptance criteria: Ensures development meets business requirements
4. Facilitating collaboration: Promotes shared understanding across the entire team

This approach results in:

• Better alignment between business goals and development efforts
• Clearer requirements documentation
• More effective regression testing
• Improved communication between all stakeholders

The Value of TailwindCSS

TailwindCSS provides significant advantages to development teams by:

1. Accelerating UI Development: Utility-first approach eliminates the need to write custom CSS, allowing faster implementation of designs.
2. Maintaining Consistency: Pre-defined design system with constraints for spacing, colors, typography, and more ensures visual consistency.
3. Reducing CSS Complexity:
   • No need to create and maintain complex CSS class naming systems
   • Minimizes CSS specificity issues and selector conflicts
   • Results in smaller bundle sizes through optimized production builds
4. Improving Developer Experience:
   • Write styles directly in your markup without context switching
   • IntelliSense support in modern IDEs provides autocomplete
   • Predictable styling behavior with direct control over every element
5. Supporting Responsive Design: Built-in responsive modifiers (sm:, md:, lg:, etc.) make creating adaptive interfaces straightforward.

This project demonstrates how TailwindCSS integrates with Angular components to create maintainable, consistent UI patterns while reducing style-related technical debt.
