Deterministic Run
A test execution that produces the same result every time given the same inputs, with no random pass or fail.

What is Deterministic Run?
A deterministic run is one whose outcome depends only on the code and inputs under test—never on timing, ordering, or luck. Determinism is what makes a test trustworthy: a red result means a real defect, and a green result means real confidence. Non-determinism, by contrast, produces flaky tests that erode faith in the whole suite. QI is built around deterministic execution: recorded flows export to plain Playwright, the AI only heals selectors rather than deciding pass or fail, so runs stay reproducible with no AI variability at run time.
