Engineers write test scripts by hand for every Lightning component change. When Salesforce updates APIs or UI patterns, entire suites need rebuilding from scratch — burning sprint cycles.

Non-deterministic failures tie up CI pipelines and erode confidence in coverage. Teams learn to ignore red — until something critical breaks in production and reaches enterprise customers.

When a test fails, finding out why means digging through logs, screenshots, and traces manually — costing hours of engineering time per incident that should be going toward new features.
