Documented steps

  1. Run `cargo test` to build and run all unit tests, integration tests (tests/ dir), and doc-tests.
  2. Filter by substring: `cargo test parse` runs every test whose name contains 'parse'.
  3. Flags after `--` go to the test harness, not cargo: `cargo test -- --show-output` prints stdout of passing tests; `cargo test -- --test-threads=1` disables parallel test execution.
  4. Scope selection: `cargo test --lib` (unit tests only), `cargo test --test <name>` (one integration test target), `cargo test --doc` (doc-tests only), `cargo test --workspace` (all workspace members).
  5. Docs: https://doc.rust-lang.org/cargo/commands/cargo-test.html
