Most brittle suites fail on harmless UI movement. Zerocheck uses semantic resolution, accessibility data, cached selectors, and confidence checks, then fails with evidence when it cannot act confidently.
“The same pattern kept repeating itself: a harmless-looking UI change, a merge, and then a failing test in CI.”

“We completely lost trust in our build, and red builds no longer meant anything.”

Testim users report 'tests do not heal themselves under any circumstance'
Selector-based healing (Mabl, Testim, Katalon) guesses alternative selectors when the original breaks. The guess can latch onto the wrong element, creating false passes that mask real bugs.
Intent-based tools (Momentic, testRigor) are more resilient but opaque. Engineers describe them as a 'black box' when they cannot inspect why the tool chose a specific action.
Engineers need evidence for passes and failures. Low-confidence behavior should fail with context rather than silently pass.
UI redesign ships. Mabl 'heals' 12 tests by finding alternative selectors. 10 heal correctly. 2 latch onto the wrong element and now validate a different flow entirely. Tests pass. Bug ships to production. Team discovers it from a customer report 3 days later.
Same redesign. Zerocheck uses semantic resolution, accessibility data, cached selectors, and confidence checks. High-confidence interactions continue; low-confidence interactions fail with screenshots and step traces instead of silently passing.
Tests describe browser intent instead of selectors
Visual interaction uses the rendered UI
Low-confidence interactions fail with screenshots and step traces
Low-confidence changes fail-closed instead of silently passing
Other tools document their own platform controls. Zerocheck produces JSON evidence from your executed application tests.
