Add comprehensive testing infrastructure and unit tests
Summary
This PR establishes testing infrastructure for llmproxy and adds unit tests for several previously untested packages. It also fixes multiple compilation errors that were preventing tests from running.
Changes include:
pkg/gateway/v1: API handlers (QueryHandler, CostEstimateHandler, DryRunHandler)pkg/circuitbreaker: Circuit breaker state management and concurrencypkg/pricing: Cost estimation and catalog managementKey fixes to existing code:
pkg/router/cost_aware.go&pkg/router/fallback.go: Fixed StatusResponse struct handling (was incorrectly treating struct as map)pkg/auth/keymanager.go: Fixed variable name conflict in decryption logicpkg/anomaly/detector.go: Fixed logrus.Entry method usageAll existing tests pass + new tests pass with race detector enabled.
Review & Testing Checklist for Human
This PR has yellow risk - medium confidence. The following items should be verified:
Critical: Test provider routing logic - The StatusResponse handling changes in
cost_aware.goandfallback.gomodified how provider availability is checked. Manually verify that provider selection, fallback behavior, and routing work correctly with different provider availability scenarios.Test auth key encryption/decryption - The variable rename in
keymanager.go:347fixed a shadowing issue but should be tested to ensure encryption/decryption still works end-to-end.Verify CI passes - This is the first CI run. Check that GitHub Actions workflow completes successfully, Go 1.25 is available, and coverage reports generate correctly.
Consider test coverage gaps - While this adds tests for 3 packages, many critical packages remain untested (jobs, monitoring, streaming, ratelimit, auth, health). Decide if current coverage is sufficient or if more testing is needed.
