Testing Validation

Testing Validation

Quick Validation

Run scripts/validate.sh for the full gate sequence.

Gate Sequence (manual)

# Minimal output mode (2026 best practice)
export CARGO_TERM_PROGRESS_WHEN=never

cargo check --message-format=short
cargo test --all-features --quiet  # or: cargo nextest run --all-features
cargo fmt --check
cargo clippy -- -D warnings

Then check LOC limits with scripts/loc-check.sh.

Benchmark Validation

# First run: save a baseline
cargo bench --bench benchmark -- --save-baseline main

# Subsequent runs: compare against baseline
cargo bench --bench benchmark -- --baseline main

Do NOT use cargo bench -- --baseline without a name — it fails silently.

Test Coverage Goals

Integration Test Files

Run tests by file:

cargo test --test <test_name>

Use separate test files in tests/ for:

• Property-based tests
• Batch operation tests
• Persistence tests
• Framework lifecycle tests
• Edge case coverage

LOC Enforcement

Every file in src/*.rs must be ≤ 500 lines. Run scripts/loc-check.sh to verify.

Documentation Link & Command Validation

Run scripts/check-docs-links.sh to validate:

• Internal file links (@file.md and [text](./path.md) style)
• External URLs (with --check-urls flag)
• Code block commands in bash/shell blocks
• Version references consistency across ALL files:
  • Core: Cargo.toml, Cargo.lock, wasm/package.json
  • Docs: README.md, book/src/getting-started.md, CHANGELOG.md, llms.txt
  • Tests: examples/cli/.sh, tests/.rs
  • Generated: export.json, csm_test.json

./scripts/check-docs-links.sh           # Quick check (no URL validation)
./scripts/check-docs-links.sh --fix     # Auto-fix version mismatches
./scripts/check-docs-links.sh --check-urls  # Full check with URL validation

Configurability Check

• Reject hardcoded tunables in new code paths.
• Require named constants and/or env/config-backed settings for thresholds, limits, and sample sizes.

Known Test Gotchas

• Reservoir tests use new_seeded(..., 42) for determinism — don't use new() in tests.
• Persistence tests need tempfile::NamedTempFile for DB path.
• Criterion closures must not capture mutable state by reference.
