Metadata

  • Branch: test/missing-asv-benchmarks-providers
  • Commit Message: test(providers): add ASV performance benchmark suite for the providers module
  • Milestone: v3.8.0
  • Parent Epic: #1678

Background and Context

The providers module (src/cleveragents/providers/) is missing a comprehensive ASV (airspeed velocity) performance benchmark suite. Per the project's Multi-Level Testing Mandate in CONTRIBUTING.md, every module must have tests at all required levels: Behave BDD unit tests, Robot Framework integration tests, and ASV performance benchmarks.

While benchmarks/provider_selection_bench.py exists and covers provider selection logic, the broader providers module contains several additional performance-critical components that have no benchmark coverage:

  • cost_table.py — cost lookup and table operations
  • cost_tracker.py — cost accumulation and tracking throughput
  • fallback_selector.py — fallback provider selection logic
  • registry.py — provider registry registration and lookup
  • llm/ — individual LLM provider adapters: anthropic_provider.py, google_provider.py, langchain_chat_provider.py, openai_provider.py, openrouter_provider.py

The providers module is a critical integration boundary in the CleverAgents architecture, implementing the Provider Registry abstraction (see docs/specification.md). It abstracts external LLM service interactions via ProviderBase using the Adapter and Strategy patterns. Performance regressions in cost tracking, registry lookups, or fallback selection would silently degrade throughput across the entire agent orchestration pipeline.

Current Behaviour

The providers module has no comprehensive ASV benchmark suite covering its full public API surface. Only provider selection is benchmarked (provider_selection_bench.py). Running nox produces no benchmark results for cost tracking, registry operations, fallback selection, or individual LLM provider adapter initialisation.

Expected Behaviour

  • A comprehensive ASV benchmark suite exists under benchmarks/ for the providers module.
  • The suite covers at least the following performance-critical paths:
    • CostTable construction, lookup, and iteration throughput
    • CostTracker cost accumulation and query latency
    • FallbackSelector selection decision throughput under various provider availability scenarios
    • Provider registry (registry.py) registration, lookup, and enumeration performance
    • Individual LLM provider adapter (AnthropicProvider, GoogleProvider, LangchainChatProvider, OpenAIProvider, OpenRouterProvider) instantiation cost
  • All benchmarks run without error via nox.
  • No existing nox sessions are broken by the addition of the benchmarks.

Subtasks

  • Audit the providers module (src/cleveragents/providers/) and identify all performance-sensitive code paths suitable for ASV benchmarking (cost table/tracker, fallback selection, registry operations, LLM adapter initialisation)
  • Create the ASV benchmark file(s) under benchmarks/ following the existing directory and naming conventions (e.g., providers_bench.py or targeted files per sub-component)
  • Implement setup / teardown fixtures as needed to isolate benchmark measurements and avoid cross-benchmark contamination
  • Implement at least one benchmark per identified performance-critical path (cost table lookup, cost tracker accumulation, fallback selection, registry lookup, LLM adapter instantiation)
  • Run nox benchmark session locally and confirm all new benchmarks execute without error
  • Verify no regressions are introduced in other nox sessions (nox -e lint, nox -e typecheck, nox -e unit_tests, nox -e integration_tests)
  • Verify coverage remains ≥ 97% via nox -e coverage_report
  • Run full nox (all default sessions) and confirm clean pass

Definition of Done

  • All subtasks above are completed and checked off
  • ASV benchmark file(s) under benchmarks/ exist and cover all performance-sensitive public behaviours of the providers module beyond what provider_selection_bench.py already covers
  • A Git commit is created where the first line of the commit message matches the Commit Message in Metadata exactly (test(providers): add ASV performance benchmark suite for the providers module), followed by a blank line, then additional lines providing relevant details about the implementation
  • The commit is pushed to the remote on the branch matching the Branch in Metadata exactly (test/missing-asv-benchmarks-providers)
  • The commit is submitted as a pull request to master, reviewed, and merged before this issue is marked done
  • All nox stages pass
  • Coverage ≥ 97%
