Software test automation on agile projects

Testing is an important phase of the software development life cycle. There are lots of new techniques, methods, tools come up for each year and also these technologies can be out of date after a short time. Considering one of the famous software development methods: Waterfall, testing can be handled at the end of project schedule and it is hard to welcome changes. Today's conditions or another way: Agile, force us to have the regular, repeated testing effort for each code commit. Therefore testing becomes one of the main cost on a software project. Manual Testing is not sufficient when the number of test case is increased and test execution frequency is higher than planned. At this point, Test automation can be suggested as a solution. Test automation makes you execute same test multiple times without any effort. When these situations are taken into consideration, it was aimed to better understand and evaluate the subject matter of the study. In this paper, we discuss the questions that " Test automation can save project cost ?" and "When a test suite should be automated or should not be automated ?".
