testing-external-dependencies

What problem does it solve?

Testing applications that rely on expensive, slow, or flaky external dependencies (APIs, ML models, media processing tools) can be costly to validate and unreliable in CI.

Core Features & Use Cases

• Three-Tier Test Architecture: Unit, integration, and end-to-end tests with controlled scopes and mocked dependencies to improve speed and reliability.
• Fake Providers for Predictable Testing: Use simplified providers to produce deterministic results, enabling repeatable E2E scenarios without real API calls.
• Test Data Management: Strategies for lightweight test fixtures, mocked data, and snapshot validation to minimize costs and variability.
• Environment-Based Configuration: Tag, skip, and selectively enable tests based on available secrets and hardware resources.

Quick Start

Configure your tests to mock external dependencies and run unit tests to validate core logic without invoking real services.
