Automated + AI visual testing
What this task is
After every release, testers click through a checklist of existing features by hand to confirm the new code hasn't broken anything that used to work.
How AI replaces it
Around 2018, automated test frameworks and continuous integration let regression suites run on every commit, and AI visual comparison later caught UI changes automatically. By 2025, manual regression passes were largely gone.
What stays human
Testers now build and maintain automated test systems, analyze why tests fail, and carry out targeted manual checks on high-risk changes that automation might not fully cover.
