Automatic test machine or automated test equipment (ATE) is any apparatus that performs tests on a device, known as the device under test (DUT), equipment under test (EUT) or unit under test (UUT), using automation to quickly perform measurements and evaluate the test results. The automation testing process, start by manually exploring new areas of the application. Then, create a risk plan that detail what needs to be automated, based business and technical priorities. Use analytics to determine end-user preferences.

Semiconductor test equipment IC tester, or automated test equipment ATE, is a system for giving electrical signals to a semiconductor device to compare output signals against expected values for the purpose of testing if the device works as specified in its design specifications.
