Dear Marcus Vance,
Automating 120 regression tests using Selenium cut release testing at my current employer from 5 days to 6 hours, directly addressing the rapid release cycles needed for VelocePay and your upcoming merchant portal update. This reduction in testing time allowed our engineering organization to ship code updates much faster without sacrificing stability or user experience.
