Pair testing

Pair testing is a way for two people to work together to check if something is working correctly. It is often used when making software or writing code. Two people sit together at the same computer and work together to test the code. One person tries to use the product and the other one watches to make sure everything looks and works correctly. Together, they can make sure the code is written correctly or that the software works well.
