The Jasmine framework is an open-source JavaScript testing framework that provides a stable and functional architecture for behavior-driven (BDD) development-inspired testing. It supports various programming languages, including JavaScript, Python, and Ruby. The framework allows developers to write tests in a descriptive style using the `describe` and `it` blocks, which group related test cases together. Jasmine also includes features such as expectations or matchers, which enable developers to implement assertions and verify expected results. Additionally, the framework provides a rich set of built-in matchers for various types of data, including numbers, strings, objects, arrays, and more. The Jasmine framework is easy to get started with and has minimal dependencies, making it an ideal choice for web UI testing and automation testing.
