Test Automation without Assertions
summary
Claim: assertion-free, snapshot-based testing (also called Golden Master Testing) catches meaningful UI changes with less brittle maintenance. Tools: Approvals Test, Jest, and the open-source recheck web (Java today, JavaScript planned) create XML golden masters, a recheck driver that wraps Selenium, a CLI to recheck commit, and a Chrome extension. Demo shows CSS break surface as 116 differences while an ID change does not break execution; retest ID gives stable virtual selectors. System works but is not unbreakable—the first run must create a golden master and fail.
