1.1.17

🐒 New Features

• Add JavaNodeTreeAdapterPlugin — an alternative object generation engine using JvmNodeTree by @seongahjo in #1264
• Add KotlinNodeTreeAdapterPlugin — Kotlin support for the node tree adapter by @seongahjo in #1264
• Add AdapterTracer — built-in tracing for debugging value resolution during fixture generation by @seongahjo in #1264
• Add object-farm-api module — JvmNodeTree, PathExpression, and type system infrastructure by @seongahjo in #1264

🌳 Node Tree Adapter Plugin

A new plugin that provides an alternative object generation path with zero overhead and built-in debugging capabilities. Starting from v1.2.0, the Node Tree Adapter will become the default object generation engine.

Java:

FixtureMonkey fixtureMonkey = FixtureMonkey.builder()
    .plugin(new JavaNodeTreeAdapterPlugin())
    .build();

Kotlin:

val fixtureMonkey = FixtureMonkey.builder()
    .plugin(KotlinPlugin())
    .plugin(KotlinNodeTreeAdapterPlugin())
    .build()

Benchmark Results (JMH, fork=1, warmup=3, iterations=10)

Scenario	Without Adapter	With Adapter	Overhead
Pure sample	125.2 ms	121.4 ms	-3.1%
set	121.7 ms	120.7 ms	-0.8%
size + setNull	122.6 ms	123.4 ms	+0.6%
Nested set	124.1 ms	124.8 ms	+0.5%
thenApply	333.3 ms	301.1 ms	-9.7%

All scenarios show near-zero overhead. thenApply is consistently ~10% faster with the adapter.

Debugging with AdapterTracer

FixtureMonkey fixtureMonkey = FixtureMonkey.builder()
    .plugin(new JavaNodeTreeAdapterPlugin()
        .tracer(AdapterTracer.console()))
    .build();

⚠️ The seed feature is not yet fully supported. Reproducibility is not guaranteed in all scenarios.
