Automation testing vs. manual testing

It has been established that performing repetitive manual testing on large software systems or those with comprehensive dataset coverage is challenging. ²

Below, you can see statistics supporting organizations’ goals of moving from manual testing to automation testing.

1. Manual testing is the most time-consuming activity in the testing cycle ( see Figure 1).
2. Test Automation has replaced 50% or more of the manual testing efforts in 46% of the cases(See Figure 2). ³
