## What it is
gock is a Go library for declarative HTTP traffic mocking that intercepts outgoing requests via http.RoundTripper and matches them against defined expectations. It offers a fluent DSL for stubbing responses with matching by method, URL, headers, and body, inspired by JavaScript's nock.

## Use cases
- mock http responses in go tests
- stub external api calls in unit tests
- intercept net/http requests during testing
- simulate network timeouts and delays in go
- test http clients without hitting real servers
- mock  api responses in go

## When to choose
- you write Go tests that make outbound HTTP calls via net/http
- you want a nock-style fluent DSL for declaring HTTP expectations
- you need regex-based request matching or TTL-limited mocks

## When to avoid
- you need to mock gRPC or non-HTTP protocols
- you prefer running a real mock server over in-process interception
- your project is not written in Go
