===Test automation tools===
Test automation tools can be expensive and are usually employed in combination with manual testing. Test automation can be made cost-effective in the long term, especially when used repeatedly in [[regression testing]]. A good candidate for test automation is a test case for common flow of an application, as it is required to be executed (regression testing) every time an enhancement is made in the application. Test automation reduces the effort associated with manual testing. Manual effort is needed to develop and maintain automated checks, as well as reviewing test results.

===Test engineer===
{{Main|Test engineer}}
In automated testing, the [[test engineer]] or [[software quality assurance]] person must have software coding ability since the test cases are written in the form of source code which when run produce output according to the [[Assertion (computing)|assertion]]s that are a part of it. Some test automation tools allow for test authoring to be done by keywords instead of coding, which do not require programming.
