Testing & Cleanup

Run Tests

cargo test
cargo test -- --nocapture

Test Layout

  • src/tests/ – in‑crate unit tests
  • tests/ – integration/property tests and fixtures

Test Storage Cleanup

Tests use temporary storage under target/dbt-nova-tests and clean up automatically.

Startup cleanup (one‑time per test run): - Removes stale temp dirs older than 5 minutes. - Controlled by: - DBT_NOVA_TEST_CLEANUP_AGE_SECS=0 → remove all temp dirs on start - DBT_NOVA_TEST_CLEANUP_ALL=1 → force full cleanup

These variables are test-only and are ignored in production runs.

Manual cleanup: 

rm -rf target/dbt-nova-tests

Fuzzing (Monthly Schedule)

Short fuzz runs are scheduled in CI on the first day of each month. To run locally:

cargo install cargo-fuzz
cargo fuzz run manifest_entity -- -max_total_time=60

Coverage

Coverage uses cargo llvm-cov (runs in CI as a separate job).

cargo install cargo-llvm-cov
cargo llvm-cov --all-features --workspace --summary-only

Snapshots

Snapshot tests live in tests/snapshots.rs. Update snapshots with:

cargo install cargo-insta
INSTA_UPDATE=always cargo test --test snapshots
