Agile testing refers to a software testing procedure in which software is checked for faults, mistakes, and other issues. It is regarded as an important aspect of the development PROCESS since it allows developers and testers to collaborate as a team, improving overall performance. It also contributes to the timely delivery of high-quality products. All the members of an agile team who have specific skills and knowledge are included in order to guarantee the timely delivery of a product with frequent releases of new features. 

Agile testing is a process that relies on agile software development concepts. It is frequently done so that testers can spot and resolve issues EARLY on in project development. In agile testing, development, and testing happen at the same time. The tester's responsibility is to act as a developer, providing improvements, recommendations, and test cases to be incorporated in the application rather than just detecting FLAWS. 

Testers cover the entire product lifecycle with agile testing, but because of effective, continuous communication and regular interaction between customers and developers, the application MAY be provided quickly without affecting product quality. Instead of having a structured plan, the testers and developers REACT to sudden changes in the process and come up with quick solutions.
