Term	Kind	Topic	What it is
Mutation Testing	tool	Mutation Testing	Deliberately introducing small faults into the code and measuring how many the test suite detects, as a measure of test strength rather than test reach.
Property-Based Testing Generative Testing, QuickCheck-Style Testing	tool	Test Architecture Strategy	Asserting invariants that must hold for all inputs, then having the framework generate many inputs to try to break them.
Service Virtualisation API Simulation, Mock Server	tool	Service Virtualisation	A stand-in for a real dependency that responds with realistic data, latency and error behaviour, so a service can be tested without it.
Synthetic Data	tool	Synthetic Data	Artificially generated data that preserves the statistical and structural properties of real data without containing anyone's actual records.
