The main goal in software development processes is to satisfy customers with timely releases of software that works flawlessly. Test automation makes it possible to execute test cases during off-peak hours, and to distribute them in parallel across multiple physical or virtual servers. Automated tests complete in a fraction of the time required for manual testing, giving the team significantly faster feedback on the quality of the application and its suitability for release.
Testing is a very important phase in the development process. It ensures that all the bugs are ironed out and that the product, software or hardware, is functioning as expected or as close to the target performance as possible. Even so, some tasks are too laborious to be done manually even though they are easy enough to do. This is where automated testing comes in. 

HP's QTP, which is launched as Unified Functional Testing, provides automated functional testing and automated regression testing. It supports scripting interfaces and offers a GUI for easy use. It can be used for enterprise quality assurance. It uses VB scripts to specify test procedures and manipulate application's objects which are being tested.
Sufficient test coverage typically demands significant effort. Hundreds of test cases may be needed to exercise all use scenarios, validate boundary and edge cases, and ensure that an application is compatible across browsers and devices. Data-driven automated testing separates test procedures from test data, allowing you to cover more scenarios with a minimum amount of effort. Easily repeat test cases across browsers or devices to ensure your application’s compatibility and consistent performance.
Many test automation tools provide record and playback features that allow users to interactively record user actions and replay them back any number of times, comparing actual results to those expected. The advantage of this approach is that it requires little or no software development. This approach can be applied to any application that has a graphical user interface. However, reliance on these features poses major reliability and maintainability problems. Relabelling a button or moving it to another part of the window may require the test to be re-recorded. Record and playback also often adds irrelevant activities or incorrectly records some activities.[citation needed]

In our automated testing starter kit, we provide a variety of resources and tools for you to use to get the ball rolling. You will learn how to efficiently roadmap your efforts, build scalable and easily-maintainable automation frameworks, and how to compare and choose the right tool based on your needs. Don’t worry, we’ve also included tips regarding what testing types should remain manual. Not all tests can or should be automated, and to reiterate our previous statement, it’s essential for your success that some testing types, like exploratory testing, are performed manually.

However, as businesses grow, they’ll likely need to implement more controls over their business processes and better alignment between information and operational technologies. At this stage, they should consider investing in business process management software to help them standardize processes and workflows for multiple departments and improve operational performance. (Not to be confused with general "business managment" software, "business process management" software carries a more specific definition and set of technical requirements.

There are various tools that help software teams build and execute automated tests. Many teams are actively using unit tests as part of their development efforts to verify critical parts of their projects such as libraries, models and methods. Historically, testing user interfaces of desktop-based applications via automated tests have been more challenging, and currently available tools for this are usually commercial and quite expensive.
