jest-extended enhances the Jest testing framework with a rich set of custom matchers. These matchers extend Jest's built-in assertions to offer more expressive and intuitive ways to test your code's behavior. Examples include matchers for testing array contents, date comparisons, string inclusion details, and object properties. This library simplifies writing comprehensive and readable tests, ultimately saving time and boosting developer confidence in code quality and reliability within Jest projects.
Jest-extended's release frequency is erratic. It started with multiple releases per month in 2017/2018, followed by long periods of inactivity. 2021 saw a resurgence with versions 1.x.x, then 2022 with 2.x.x and 3.x.x.
