Jest and Vitest are two well-known JavaScript testing frameworks, each with its own strengths. Jest, created by Facebook, is especially popular for React applications. It provides a "zero-config" setup, built-in code coverage reporting, and snapshot testing, making it a complete solution for many JavaScript projects. Vitest, a newer framework in the Vite ecosystem, is known for its speed and lightweight design. Using Vite’s dev server, Vitest performs very well, especially in larger projects.

Software testing that confirms if a system or application satisfies the necessary specifications and business needs is called acceptance testing. It is usually performed at the end of the software development life cycle, after unit testing and integration testing have been completed. The main goal of acceptance testing are to : Instead of the development team, end users, business stakeholders, or customers frequently conduct acceptance testing.

Modern software testing now relies heavily on test automation, which helps teams produce reliable, error-free software more quickly and confidently.

Manual testing is a fundamental yet essential process in software development where testers manually execute test cases without the use of automation tools. Despite advancements in automation, over 30% of global testing efforts are still carried out manually, according to industry research.
