ci: optimize test workflow to reduce CI runtime#180
Merged
Conversation
- Remove `cargo build --release` from lint job (fmt, clippy, and unit tests only need debug builds) - Move single binary architecture verification to integration-tests where the release build already happens - Merge homebrew-simulation job into integration-tests(macos) using conditional steps, eliminating a redundant macOS release build - Replace manual actions/cache with Swatinem/rust-cache@v2 for smarter Rust-specific caching with automatic target pruning Reduces total job count from 5 to 4 and eliminates two redundant `cargo build --release` invocations.

Summary
lintjob (formerlyunit-tests) only runscargo fmt --check,cargo clippy, andcargo test --lib— none of which need--release. Thecargo build --releaseand single binary architecture verification have been moved tointegration-tests, where the release build already happens.homebrew-simulationintointegration-tests(macos): Both jobs ran onmacos-latestand built the same release binary. The Homebrew simulation steps are now conditional (if: matrix.os == 'macos-latest') withinintegration-tests, eliminating a redundant macOS release build.actions/cachewithSwatinem/rust-cache@v2: Purpose-built for Rust projects — automatically handles cache key derivation, target directory pruning, and per-job cache isolation.Before: 5 parallel jobs (unit-tests, integration-ubuntu, integration-macos, homebrew-sim, xtask-test)
After: 4 parallel jobs (lint, integration-ubuntu, integration-macos, xtask-test)
Net effect: 2 fewer
cargo build --releaseinvocations (lint job drops release build entirely, homebrew-sim merged into integration-macos), and smarter caching across all jobs.Test plan
