Redundancy is one of key concerns, which kills the productivity in employees.
People want to do something new and something different.
So it is obvious for organizations to get the obvious thing out.
Switching from manual software testing practices to test automation means processes are expedited and issues are identified faster. The quality of software is greatly improved, and most clients report an overall reduction in project stress levels.
Test automation significantly decreases test execution time and can get the early feedback on the product with the nightly builds and can help the teams to understand the impact on the changes committed in previous day.
So, to understand the impact on the system, it is very important to identify the issues at the earliest, Which cannot be achieved on daily basis with manual effort.
With Manual testing there is always a chance of leaking defects, if we have to deliver frequently with shorter release cycles.
