What problem does it solve? Writing consistent, high-quality tests for an AI agent platform is time-consuming and error-prone, especially when tests must stay deterministic and isolated from external services. This Skill standardizes test generation so every test follows the same pytest conventions and mocking rules. ## Core Features & Use Cases - Multiple Test Types: Generates unit tests, integration tests, workflow tests, agent tests, tool tests, and API endpoint tests. - Enforced Testing Standards: Ensures tests verify correctness, isolate dependencies, remain deterministic, and never call real external services. - Consistent Project Layout: Places tests in a tests/ directory mirroring the source structure with test_ naming conventions. - Use Case: When adding a new agent tool, ask for test coverage and receive pytest unit tests for the tool logic plus integration tests for the agent-to-tool interaction, with all external APIs mocked. ## Quick Start Generate pytest unit and integration tests for my new agent tool with all external API calls mocked.
