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.
Automation testing has become an absolute necessity in an agile and fast-paced business environment with an immense focus on accelerated time to market. However, as far as automation is concerned, Selenium automation testing still reaps the maximum benefits in terms of test coverage and browser coverage.
