Adds the isolated Kevlar.Testing package with immutable typed pipeline descriptors and framework-independent shape assertions. Integrates public API, package consumer, documentation, and CI checks; production execution paths gain no hooks or allocations. Validation: Release build; 563 unit, 1 netstandard, 16 integration, 19 analyzer, 5 testing, and 2 allocation tests; package verification; 83 documentation snippets; Docusaurus build. Closes #97.

Summary by CodeRabbit

  • New Features
    • Added the Kevlar.Testing package for inspecting shield pipelines without executing them.
    • Added descriptors for pipeline metadata, strategy order, configuration, callbacks, and backoff settings.
    • Added framework-independent assertions for strategy counts, ordering, and descriptor types.
  • Documentation
    • Documented pipeline inspection, assertions, package usage, and coverage commands.
  • Tests
    • Added comprehensive coverage for descriptors, strategy metadata, assertions, and immutable snapshots.
    • Integrated the testing suite into automated builds and coverage reporting.

Limit details: You’ve used all 10 included reviews currently available.

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

Wait for the limit to reset, then comment @coderabbitai review or push new commits to the PR.

An organization admin can change what happens after included review limits in Billing.

How do review limits work?

CodeRabbit enforces per-developer PR review limits within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

The PR adds the Kevlar.Testing package. It provides immutable shield and strategy descriptors, descriptor assertions, internal inspection metadata, strategy execution updates, package validation, documentation, and automated test and coverage integration.

Changes

Pipeline descriptors and strategy support

Layer / File(s) Summary
Internal strategy inspection metadata
src/Kevlar/Backoff.cs, src/Kevlar/Strategy.cs, src/Kevlar/Strategies/..., src/Kevlar/Kevlar.csproj, tests/Kevlar.Tests/...
Kevlar exposes internal configuration, callback, notification, fallback type, and backoff metadata to Kevlar.Testing.
Descriptor contracts and project API
src/Kevlar.Testing/*.cs, src/Kevlar.Testing/*.txt, src/Kevlar.Testing/Kevlar.Testing.csproj
The package defines immutable shield and strategy descriptors, strategy and backoff kinds, assertion exceptions, and public assertion APIs.
Descriptor extraction and assertions
src/Kevlar.Testing/ShieldDescriptorExtensions.cs, src/Kevlar.Testing/ShieldDescriptorAssertionExtensions.cs, tests/Kevlar.Testing.Tests/*
Shield descriptors capture ordered strategy metadata without execution. Assertions validate descriptor presence, uniqueness, count, and order.
Circuit breaker and concurrency execution
src/Kevlar/Strategies/CircuitBreaker/*, src/Kevlar/Strategies/ConcurrencyLimit/*, tests/Kevlar.Tests/ConcurrencyLimitTests.cs
Circuit breaker execution supports asynchronous state handling, notifications, and dynamic break durations. Concurrency limits use atomic permits and queued waiter transfer.
Package integration and validation
Kevlar.slnx, .github/workflows/ci.yml, scripts/*, docs/docs/testing.md, README.md, tests/Kevlar.DocTests/Kevlar.DocTests.csproj
Solution entries, package checks, documentation, sample consumers, test execution, and coverage commands include Kevlar.Testing.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🟠 High · up to 6732c

The PR adds synchronous circuit-breaker monitor operations that can deadlock applications using asynchronous state-change callbacks, and fallback descriptors may still report valid notification configurations incorrectly. These correctness and availability risks should be fixed before merge.

Poem

A rabbit checks each shield in line,
With descriptors neat and fine.
Count and order, clear and bright,
Callbacks sleep through every test night.
“Hop!” says the suite, “The shapes are right!”

679-688: 🩺 Stability & Availability | 🟠 Major | 🏗️ Heavy lift

Reject synchronous monitor operations when OnStateChangedAsync is configured. CircuitBreakerMonitor.Isolate() and Reset() wait synchronously for PublishAsync. If the callback resumes on the caller’s single-threaded synchronization context, either method can deadlock. Require IsolateAsync() and ResetAsync(), or throw a clear InvalidOperationException from the synchronous methods.
