Deterministic Test Execution
Deterministic test execution is a testing approach in which a test produces the same outcome every time it runs under the same inputs, environment, and system state. It eliminates or controls sources of nondeterminism such as timing dependencies, random data, shared state, network variability, and asynchronous race conditions. Deterministic execution improves test reliability, reproducibility, and debugging efficiency.
