# describe Describe is a testing toolkit for writing legible, ergonomic unit tests. # Getting started Describe exposes one function for creating a new test case, `assert_that`. ```Rust use describe::assert_that; // An example function to test. fn get_answer_to_life() -> u8 { 42 } ... // Assert that the answer to life is 42. assert_that(&get_answer_to_life()).is(&42); ```
