" summary

Teams at Pensionsmyndigheten find subtle GUI regressions (button border, length and color shifts) across more than 25 e‑services and replace slow manual checks that take 1–3 hours with automated visual diffs that run in 1–3 minutes. Several tools are evaluated and BackstopJS is chosen; configuration is ~40 lines, tests target selectors and three viewports, screenshots are compared, diffs highlighted, and the pipeline prevents regressions before deployment.
