 SQL parser and storage engine with **zero dependencies**. You give it SQL strings;
 it creates databases and tables, stores rows, and answers `SELECT` queries.

 npm test

-Runs the assertion suite in `test/` (Node's built-in test runner — no
-dependencies). It covers projection order and subsets, `WHERE` filtering,
-name-based table/database resolution, `DROP`, and the error paths
-(no database selected, missing table, unsupported statement).
+That runs `node --test` over `test/` — Node's built-in test runner, so there is
+nothing to install first. 28 assertions across two files:
+
+| File | Covers |
+|---|---|
+| `test/sql.test.js` | statement level: projection order and subsets, `WHERE` filtering (one match, many matches, none), name-based table/database resolution, `USE`, `DROP TABLE` / `DROP DATABASE`, case-insensitivity, the optional trailing semicolon, and the error paths (no database selected, missing table, unknown column, unsupported statement) |
+| `test/table.test.js` | storage level: column names and types, `getDataForColumn`, inserts naming an unknown column, table lookup/drop on `Database`, and `Row` get/set |
+
+To run a single file:
+
+```bash
+node --test test/sql.test.js
+```
+
+To re-run the suite as you edit:
+
+```bash
+node --test --watch
+```
+
+Every push and pull request runs the same suite on Node 18, 20, 22, and 24 via
+GitHub Actions ([`.github/workflows/test.yml`](.github/workflows/test.yml)) —
+that's the badge at the top.
