history
Project history and usage
counterfeiter is a Go code generator for creating self-contained, type-safe test doubles from interfaces.
Project history
The public repository was created in 2014. Its README frames the project around a Go-specific testing problem: fake implementations are useful for unit tests but cannot be generated automatically at runtime in Go.
The project has continued through a v6 release line, with current documentation using Go modules and Go tool dependencies.
Adoption history
counterfeiter's documented workflow follows Go ecosystem conventions: add it as a tool dependency, place `go:generate` or `counterfeiter:generate` directives near interfaces, and regenerate fakes with `go generate`.
The README notes that the project has largely been maintained by the community, which fits its role as a small but durable testing utility rather than a framework-owned generator.
How it is used
Typical use is to generate fakes for interfaces in the same module or for third-party interfaces, then import the generated `foofakes` package in tests to inspect call counts, arguments, and stubbed return values.
Why package nerds care
For package maintainers, counterfeiter is a good example of a Go CLI whose preferred installation changed with Go tooling: Homebrew can ship a binary, but the upstream docs now prefer module-pinned tool dependencies for reproducible generation.
