Class InstancioArgumentsGeneratorFactory

java.lang.Object
edu.berkeley.cs.jqf.fuzz.instancio.InstancioArgumentsGeneratorFactory
All Implemented Interfaces:
ArgumentsGeneratorFactory
public final class InstancioArgumentsGeneratorFactory extends Object implements ArgumentsGeneratorFactory
Builds Instancio-backed ArgumentsGenerators.

This is a second reference provider, alongside the junit-quickcheck one. It exists to show that ArgumentsGeneratorFactory is generation-library agnostic: the engine and both run paths drive it without depending on Instancio. It is discovered through ServiceLoader, or selected per test with @FuzzTest(arguments = InstancioArgumentsGeneratorFactory.class).

Instancio is a seed-based generator, so Zest steers it through a single seed per parameter rather than a byte-by-byte decoding. That gives coarser control than junit-quickcheck; see the module README for the trade-off.
