A framework is a collection or set of tools and processes that work together to support testing and developmental activities. It contains various utility libraries, reusable modules, test data setup, and other dependencies. Be it web development or testing, there are multiple frameworks that can enhance your team’s efficiency and productivity. Web testing, in particular, has a plethora of frameworks, and selecting a framework that suits your needs depends on your language of choice.
