Why test automation breaks down without the right execution layer

Stuck in the UI loop

Clicking “Run” in Studio doesn't scale. You need tests that trigger automatically across machines, builds, and environments.

No CI/CD, no continuity

Without automation in your pipeline, test execution lags behind your dev cycles, causing misalignment and last-minute surprises.

Environments cause chaos

Tests pass locally, then fail in staging or prod. Why? You’re missing a consistent execution layer that runs the same way everywhere.
