Automation testing is a process where an application under test is tested automatically by using a software tool. It is also known as Test Automation. It is mainly used to reduce the number of regression tests that need to be run manually by testers after the completion of each sprint or iteration in Agile/Scrum methodology.

There are various types of automation testing tools available in the market such as Selenium Quick Test Professional (QTP) and Rational Functional Tester (RFT). Each tool has its own advantages and disadvantages.

Automation testing frameworks are tools that help in automating the process of testing software to ensure quality and accuracy. Agile/Scrum methodology is a popular framework used in software development. Automation testing frameworks can be used in agile/scrum methodology to automate the process of testing software at various stages of development. This helps in reducing the time and effort required for manually testing the software. Automation testing frameworks also help in increasing the coverage of tests and ensuring that all aspects of the software are tested.

Automation testing is a process where an application under test is tested using an automated tool to verify if it meets the requirements as mentioned in the requirement specification documents. It is mostly used in Agile methodology where the sprint duration is 2-4 weeks and there are multiple releases in a year. In scrum, every sprint has a goal that needs to be achieved and hence regression testing becomes very important to ensure that there are no new bugs introduced in the code and that all the features are working as expected.

There are various open-source and commercial tools available in the market for automation testing like Selenium Quick Test Professional (QTP) Rational Functional Tester (RFT) etc. But selecting the right tool for the project is very important because it should be able to support the application under test and also meet the budget.
