patch

Offers an easy-to-use interface with sensible defaults, as highlighted in the README's features, making it straightforward to integrate with ExUnit tests.

Provides first-class utilities for mocking Elixir Processes and GenServers, including intercepting messages and injecting listeners, which simplifies testing concurrent code.

Keeps testing logic completely separate from application code without requiring modifications, ensuring clean separation of concerns as emphasized in the philosophy.

Enables patching of private functions without changing visibility and ensures mocks work for both local and remote calls, offering capabilities not found in other Elixir mocking libraries.

Supports complex mock behaviors with scalars, callables, sequences, cycles, and exceptions, allowing for dynamic and realistic test scenarios as detailed in the value builders section.
