WireMock
WireMock is an open-source HTTP service virtualization tool that simulates APIs through programmable request matching, responses, and interaction verification.
Logs and Telemetry
WireMock is a tool for mocking HTTP-based APIs and inspecting or controlling their requests and responses.
- How it is used
- Provides a local HTTP destination for validating Fluent Bit HTTP and OpenTelemetry output delivery.
- How deep it goes
- Explains startup, endpoint configuration, request retrieval, and payload inspection without detailing WireMock mapping syntax.
- Examples
- Uses a localhost `/simple` HTTP endpoint and recorded OpenTelemetry metrics, logs, and traces requests viewed in Postman.
- What you can do after
- Diagnose/debug with it by inspecting locally recorded requests and validating output headers or basic-auth credentials.
Build Financial Software with Generative AI (From Scratch)
WireMock is a tool for mocking HTTP-based services with programmable request matching and predefined responses.
- How it is used
- Supports frontend development and UI testing when backend APIs are incomplete or unavailable.
- How deep it goes
- Explains Docker setup, volumes, mappings, response files, refreshes, and dynamic templating, while deferring advanced WireMock features.
- Examples
- Uses Hello World, ACH file responses, ACH batch data, administration endpoints, and a scatterplot dashboard.
- What you can do after
- Operate/configure WireMock through Docker, mappings, canned response files, administration refreshes, and dynamic URL templating.
