Jest is currently working on providing a programmatic API. This is under development, and usage of this package directly is currently not supported.
Mocha is a feature-rich JavaScript test framework running on Node.js and in the browser, making asynchronous testing simple. It's similar to @jest/core in providing a testing framework, but differs in its interface and default behavior, such as having a different assertion library by default (Chai) and not including a mocking library.
Jasmine is a behavior-driven development framework for testing JavaScript code. It does not require a DOM, and it has a clean, obvious syntax so that you can easily write tests. Compared to @jest/core, Jasmine is more focused on the BDD aspect and comes with an assertion library out of the box, whereas Jest provides more utilities for mocking and spying.
AVA is a test runner for Node.js with a concise API, detailed error output, and process isolation for concurrent tests. It's designed to be fast and comes with built-in support for ES6. Unlike @jest/core, AVA emphasizes minimalism and parallel test execution, which can lead to faster test runs for certain projects.
