Gemini: Different Ways to Use It
summary
Gemini is a visual-regression tool that captures screenshots of page elements and compares them either to stored baselines or to another fresh run. It trades off seven metrics (reliability, reproducibility, infra, run time, analysis time, write time, maintenance time) and supports a testing mode using git-lfs baselines and an optipng plugin for high reliability at the cost of storage and upkeep, or a comparison mode for fast one-off checks on dynamic production that can miss bugs present in both runs. Yandex uses Gemini in production; adding a new browser may require re-recording about 600 baselines.
