Expects: Expressive TDD/BDD Assertion Library

Expects is an expressive and extensible TDD/BDD assertion library for Python, designed to make test assertions clear and readable in a TDD/BDD style. It supports a wide range of built-in matchers and allows for defining custom ones. The current stable version is 0.9.0, released in October 2018. Given the age of the last release, the library is in a maintenance state rather than active development.
