Bug0
Bug0 is managed AI QA: a forward-deployed engineer builds end-to-end tests on Bug0's engine, covering critical flows in seven days. Tests heal themselves when the UI changes, and every failure is verified before it reaches you. It also publishes Passmark and a substantial testing blog.
- Sells ownership of test maintenance, which is why suites actually rot
- A forward-deployed engineer learns your critical flows in a way no tool does
- Verified failures prevent the flakiness that trains teams to ignore alerts
- Self-healing addresses the class-rename problem that breaks suites weekly
- A suite someone else maintains is a suite you do not fully own
- Portability and what you retain after an engagement are unstated
- Self-healing can pass while checking the wrong element, which is the dangerous failure
