stateful-mocks

What problem does it solve?

This Skill enables developers to create mocks that replicate complex stateful interactions, essential for reliable testing of systems under conditions like race scenarios, retries, and state transitions.

Core Features & Use Cases

• Sequential Call Simulation: Mock methods to return different results on subsequent calls.
• State Transition Emulation: Mimic system state changes across multiple mock invocations.
• Use Case: Test a web controller handling double-submit errors by simulating a successful first call and a conflicting second call to ensure proper error handling.

Quick Start

Use the mock pattern to simulate a function that succeeds once then fails, verifying your error response.
