Introducing Efx Library for Declarative and Testable Effects in Elixir

Source: reddit.com

Type: Discussion

Efx is a specialized Elixir library designed to streamline the definition and testing of side effects in a declarative manner. Unlike traditional mocking frameworks, Efx significantly reduces implementation overhead while emphasizing testable code. A unique feature of Efx is its utilization of the relatively new ancestor-keys from the process dictionary, which helps track bindings for tests, even for child processes. This makes it easier to implement tests asynchronously. For more details or to provide feedback, check out the project's GitHub page. The library is also available on Hex.
