Manual testing is the process of verifying that software works as
required by physically using the functions and features of an application as an end-user would,
including their potential mistakes, with the aim of making sure that the software is free from
defects. Manual testing allows us to understand the problem on a conceptual and emotional
level. It connects us with the end-user and introduces us to a level of empathy automated
testing doesn’t provide. Our manual tester follows a critical-path functionality that makes sure
the program is free of any errors from the user point of view.
