expectLY

expectLY is a JavaScript library designed to simplify asynchronous testing in Node.js environments. It provides a fluent API for writing assertions and managing expectations around asynchronous operations, such as promises and callbacks. The core functionality of expectLY revolves around its `expect` function, which allows developers to wrap asynchronous values and chain assertion methods to them.

Key features of expectLY include its ability to handle timeouts, assert on promise resolutions and rejections, and integrate with common Node.js testing frameworks like Mocha and Jest. The library aims to reduce the boilerplate code typically associated with asynchronous testing, making tests more readable and maintainable. It offers a range of matchers for common assertion types, such as checking for specific values, types, or the presence of elements.

expectLY was developed to address some of the complexities inherent in testing asynchronous JavaScript code, where timing and the order of operations can be difficult to control and verify. By providing a structured and expressive way to handle these challenges, expectLY helps developers write more robust and reliable test suites. The library is open-source and available for use in Node.js projects.
