This paper focuses on establishing test automation as a service in the software development organization at the outset, with the importance being given especially to the testing group. Test automation should direct its efforts to increase the efficiency and effectiveness of the manual testing process by providing 'Quality' Test Automation services. Test Automation should always aim at supplementing the manual testing to quickly assess the quality of the application under test through the execution of quality test automation suites. The building blocks of test automation services are discussed thoroughly to successfully finish test automation projects.
