Glossary
Autonomous testing is a broad term for systems that perform testing work with limited intervention. Vendors use it for different levels of planning, authoring, execution and maintenance.
The label does not tell a buyer who defines correctness, which actions are allowed or how much review is needed. Those responsibilities should be explicit.
Teams ask the system to execute a real requirement, inspect its assertions and test a deliberate failure. They establish boundaries for fixtures, side effects and release decisions.
Zerocheck automates execution of team-described browser flows. Your team chooses the requirements and test data, reviews drafted steps and investigates results. It does not independently discover a complete suite or decide whether to release.
