Test Automation ROI
Test automation ROI should take into account qualitative factors not just quantitative:
The risk that a human can make a mistake while testing manually. This one is very significant when it comes to testing a complex scenario, such as a financial calculation.
Distractions and the monotony level of testers during manual execution should not be ignored. People simply don’t actively engage in testing that is boring and they zone-out causing them to miss defects that should have been caught.
