Testing Core

About

Testing Core provides developers with a standardized framework for building reliable test suites across multiple programming languages including Python, TypeScript, and Rust. It emphasizes the Test Pyramid approach, balancing fast unit tests with comprehensive integration and E2E flows, while providing specific patterns for the Arrange-Act-Assert (AAA) structure and mocking external dependencies. A key highlight is its focus on critical smoke tests, ensuring that applications not only pass logic checks but are actually operational and responsive in real-world environments.

Key Features

• Critical smoke test patterns to verify application health and startup status
• Standardized AAA (Arrange-Act-Assert) test structures for cross-team consistency
• Integration testing templates for database operations and RESTful API endpoints
• Language-specific examples for Python (pytest), TypeScript (Vitest), and Rust
• Comprehensive mocking patterns for external APIs, services, and time-based logic
• 0 GitHub stars

Use Cases

• Establishing a high-quality testing foundation for a new software project
• Creating automated verification gates to prevent broken builds in CI/CD pipelines
• Refactoring legacy code by implementing reliable unit and integration test coverage
