cherrypick/benchmark_cherrypick

benchmark_cherrypick

Benchmarks for performance and features of the cherrypick (core) DI container.

All scenarios use the public API capabilities of cherrypick (scope, module, binding, scoping, and async support).

Scenarios

• RegisterAndResolve: basic registration and resolution of a dependency.
• ChainSingleton (A->B->C, singleton): dependency chain, all as singletons.
• ChainFactory (A->B->C, factory): dependency chain with factory bindings (new instance on each request).
• NamedResolve (by name): resolving a named dependency among multiple implementations.
• AsyncChain (A->B->C, async): asynchronous dependency chain.
• ScopeOverride (child overrides parent): overriding a dependency in a child scope over a parent.

Benchmark results

Scenario	RunTime (μs)
RegisterAndResolve	0.3407
ChainSingleton (A->B->C, singleton)	0.3777
ChainFactory (A->B->C, factory)	0.9688
NamedResolve (by name)	0.3878
AsyncChain (A->B->C, async)	1.8006
ScopeOverride (child overrides parent)	0.3477

How to run

1. Get dependencies:

   dart pub get
   

2. Run the benchmarks:

   dart run bin/main.dart
   

A text report with all metrics will be displayed in the console.

To add your custom scenario — just create a new Dart file and declare a class extending BenchmarkBase or AsyncBenchmarkBase, then add its invocation to main.dart.
