GoMock (go.uber.org/mock) is a mocking framework for Go that generates mock implementations of interfaces via the mockgen code-generation tool. It is a maintained fork of Google's archived golang/mock, actively maintained by Uber and integrated with Go's built-in testing package.

Use cases

• generate mocks for Go interfaces
• unit test Go code with mock dependencies
• mock database driver interfaces in Go tests
• replace the abandoned golang/mock project
• set up go:generate-based mock generation
• verify expected method calls in Go tests

When to choose

• you need a mature, actively maintained mocking framework for Go
• you want generated mocks from interface definitions with source, package, or archive modes
• you're migrating from Google's unmaintained golang/mock
• you want tight integration with Go's standard testing package

When to avoid

• you prefer hand-written fakes or stubs over generated mocks
• you're not writing Go code
• you need runtime mocking without code generation
• you prefer a lightweight assertion-only library without mock generation
