Playwright-BDD Enterprise Automation Framework
A production-grade testing engine bridging Gherkin-readable scenarios with Playwright's execution power.
Overview
I architected and deployed a highly scalable test automation engine designed to validate a complex financial services operations console. Engineered to be a lightweight and easily extensible framework, it provides first-class BDD support seamlessly translating business-readable feature files into parallelized, highly stable automated tests across 11+ business domains and 26 authenticated API roles. This architecture was specifically designed to tighten the feedback loop and accelerate test development velocity, ensuring high-quality deployments at scale without sacrificing developer agility.
The Challenge & Solution
Testing enterprise financial software requires handling complex, multi-role authentication and massive amounts of test data safely. I designed this framework around a Dynamic Role Registry and a Service Object Model to eliminate boilerplate. Adding a new role requires zero infrastructure code changes, and custom Playwright fixtures ensure guaranteed server-side data teardown, even when tests fail.
Key Engineering Highlights
Scalable Architecture
Implemented an Abstract BaseAPI class extended by 15+ domain-specific clients, supporting positive/negative testing through a shared assertStatus() method.
Advanced State Management
Developed custom Playwright fixtures (sessionCtx, responseCtx, cleanupCtx) to seamlessly handle multi-role API authentication, efficient bearer token caching, and cross-step data sharing.
Parallel Multi-Project Execution
Configured dependency chains to separate API and UI test suites, allowing them to run in full parallel with independent global setup phases.
Developer Experience (DX)
Integrated a custom Allure listener for Cucumber-style reporting, a built-in VitePress documentation site, and a custom CLI tool for importing JIRA Xray feature files.
AI Integration
Leveraged GitHub Copilot agents and skills to accelerate the porting of legacy tests into the new modern architecture.
