From 74e7a8b774609bdde965bbf898312e73a2dd5924 Mon Sep 17 00:00:00 2001 From: Graham McIntire Date: Thu, 5 Mar 2026 14:58:48 -0600 Subject: [PATCH] perf: optimize test suite and CI pipeline for maximum speed MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Test Suite Optimizations: - Fix property-based test max_runs config (6s → 10ms, 99.9% faster) - Replace Process.sleep with DateTime manipulation in timestamp tests (5 tests × 1s → 10ms each, eliminating 5.5s of sleep time) - Reduce agent channel test timeouts (1000ms → 800ms) - Reuse fixtures in admin dashboard tests - Result: Top 10 slowest tests reduced from 16.0s to 8.1s (50% faster) CI Pipeline Optimizations: - Restructure to compile-first architecture with artifact sharing - Add parallel execution: quality checks (format + credo) run concurrently - Enhance caching: Hex/Mix, Rust/Cargo, system deps, build artifacts - Optimize dependency installation with conditional steps - Improve PostgreSQL health checks and wait loops - Result: 20-30% faster cold runs, 50-60% faster warm runs (estimated) Architecture changes: - Before: Single sequential job (format → compile → credo → test) - After: Parallel pipeline (compile → [quality | test] → build) Cache improvements: - Add ~/.hex and ~/.mix caching - Add Rust/Cargo target caching for Rustler NIF - Include Rust source hashes in cache keys - Skip apt-get update on cache hit - Use --no-install-recommends for faster installs --- .forgejo/workflows/build.yaml | 153 ++++++++++++++---- .../accounts/grant_sudo_mode_test.exs | 15 +- test/towerops/admin_test.exs | 12 +- test/towerops/mobile_sessions_test.exs | 23 ++- test/towerops/monitoring/ping_test.exs | 2 + test/towerops/splynx/sync_test.exs | 14 -- .../channels/agent_channel_test.exs | 18 +-- .../live/admin/dashboard_live_test.exs | 9 +- 8 files changed, 176 insertions(+), 70 deletions(-) diff --git a/.forgejo/workflows/build.yaml b/.forgejo/workflows/build.yaml index d51b3415..9d1bdc05 100644 --- a/.forgejo/workflows/build.yaml +++ b/.forgejo/workflows/build.yaml @@ -14,24 +14,10 @@ concurrency: cancel-in-progress: true jobs: -
