Autonomous Testing Is Shipping Broken Agents. Visual Regression Testing Solves It.

Autonomous Testing Is Shipping Broken Agents. Visual Regression Testing Solves It. Your test suite passed. 347 tests. All green. Your agent shipped and broke the customer's workflow on the first run. This is the QA blind spot with autonomous agents: traditional test coverage doesn't catch agent behavioral failures because agents don't execute like code. Why Traditional Testing Fails for Agents Test suites work for code because code is deterministic. Same input → same output (always). You test the inputs. You verify the outputs. Done. Agents are non-deterministic. Same input → different output (depending on LLM response, API latency, decision branches). Your test for "agent extracts customer name from form" passes because: You mock the form HTML Agent extracts "John Doe" Test asserts extraction worked Test passes Production runs the same agent against a slightly different form layout. Agent extracts "Doe, John" instead (different HTML structure). Test never caught this because you teste
