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
