assertly

Assertly is a JavaScript testing utility that provides a fluent interface for making assertions. It is designed to be readable and expressive, making it easier to write and understand test cases. Assertly allows developers to chain multiple assertion methods together, creating a more natural language-like syntax.

The library supports a wide range of assertion types, including checks for equality, truthiness, falsiness, presence, type, and more. It also offers assertion methods for arrays and objects, such as checking for inclusion, length, and property existence. Assertly aims to reduce the boilerplate code often associated with testing frameworks by providing concise and descriptive assertion functions.

Assertly can be used in various JavaScript environments, including Node.js and browsers. It is often integrated with popular testing frameworks like Mocha or Jest, although it can also be used as a standalone assertion library. The goal of Assertly is to enhance the developer experience in writing tests by promoting clarity and reducing complexity in assertion logic. Its design emphasizes readability to help developers quickly identify failures and understand the expected outcomes of their tests.
