## What it is
Hamms is a Python library and CLI tool that runs a set of deliberately broken HTTP servers on ports 5500-5600 to elicit failures in HTTP clients. It simulates connection errors, malformed responses, slow servers, oversized headers, and other edge cases.

## Use cases
- test how my http client handles malformed responses
- simulate a server that hangs and never responds
- test http client timeout and retry logic
- verify client behavior with huge response headers
- test handling of mismatched content-length responses
- simulate slow servers trickling bytes
- test arbitrary http status code responses

## When to choose
- you need to test HTTP client resilience against network failures and malformed data
- you want deterministic, local failure simulation without mocking libraries
- you are writing integration tests for timeout, retry, and error handling paths

## When to avoid
- you need to test HTTPS/TLS-specific behavior
- you want a general-purpose HTTP mocking framework with request expectations
- you need actively maintained tooling - the latest release dates to 2017

## Facets
