Mokksy and AI-Mocks

Mokksy and AI-Mocks are mock HTTP and LLM (Large Language Model) servers inspired by WireMock, with support for response streaming and Server-Side Events (SSE). They are designed to build, test, and mock OpenAI API responses for development purposes.

Mokksy and AI-Mocks are a suite of tools designed for mocking HTTP and LLM (Large Language Model) APIs for testing and development purposes.

  1. Mokksy

    • A mock HTTP server built with Kotlin and Ktor
    • Supports true Server-Side Events (SSE) and streaming responses
    • Designed to overcome limitations in existing tools like WireMock
    • Provides a flexible, fluent Kotlin DSL API

  2. AI-Mocks

    • Specialized mock server implementations built on top of Mokksy
    • Currently supports:
      • OpenAI API (ai-mocks-openai)
      • Anthropic API (ai-mocks-anthropic)
    • Allows developers to mock LLM API responses for testing and development
  • Streaming Support: True support for streaming responses and Server-Side Events (SSE)
  • Response Control: Flexibility to control server responses directly
  • Delay Simulation: Support for simulating response delays and delays between chunks
  • Modern API: Fluent Kotlin DSL API with Kotest Assertions
  • Error Simulation: Ability to mock negative scenarios and error responses
