Automated End-to-End Testing Framework for Cryptocurrency Platforms

A scalable automated testing framework built with TypeScript and Playwright for testing cryptocurrency platforms such as CoinMarketCap.

The project implements a dual-layer testing strategy covering both REST API and Web UI, focusing on data integrity, user workflows, error handling, and reliable regression testing.

Key Features

• API Testing: Validate cryptocurrency data, HTTP status codes, response structure, sorting, and negative scenarios.
• UI Testing: Automate cryptocurrency search, navigation, page rendering, and user interactions.
• Page Object Model (POM): Separate page elements and test logic for maintainability.
• API Service Layer: Centralize API request logic for reusable test components.
• Reliable Assertions: Use Playwright web-first assertions to reduce flaky tests.
• Test Reporting: HTML reports with screenshots, videos, and traces captured on failures.
• Scalable Architecture: Designed for future CI/CD, cross-browser, and data-driven testing.
