The aim of this paper is to explain important software quality components, software testing, and testing types to clarify each of these processes in detail, as well as their importance in deciding on automating software testing. Any software behavior that does not comply with user requirements is the error that needs to be identified and removed. In a wider sense, testing is a quality control system that checks its characteristics and components. Testing can be done manually or automatically. Automatical testing implies the use of automatic tools executed by software testing. The goal of automatization is to reduce the number of test cases manually triggered, but not to eliminate manual testing. When deciding on automatization, it is necessary to consider that automatic testing requires substantial investments in money and resources. The biggest advantages of testing automation are: efficiency, the launch of existing (regression) tests on a newer version of the program, the ability to run multiple tests in less time enabling them to run more often, to run tests that would be difficult or impossible to do manually, better use of human resources and consistency and repeatability of the test. One of the most commonly used tools for automatic software testing is Selenium, Katalon Studio, UFT, Test Complete and Soup UI. Although there are great advantages of automatical testing tools, there is still a need for expertise to determine the priority of the tests, to evaluate the usefulness of the tests, and to make the. Automated testing tools sometimes lack imagination and are not flexible and for that reason at least in some cases manual testing will be preferable.
