Write Tests for stream-csv-as-json

Write or update tests using the tape-six testing library.

Steps

1. Identify the module or feature to test. Read its source code to understand the public API.
2. Check existing tests in tests/ for stream-csv-as-json conventions and patterns.
3. Create or update the test file in tests/:
   • ESM tests use .mjs extension, CJS tests use .cjs, TS tests use .mts.
   • import test from 'tape-six';
   • import chain from 'stream-chain';
   • Import the module under test with relative paths: import parser from '../src/parser.js';
   • Use tests/read-string.mjs helper for streaming strings in configurable chunks.
   • Use test.asPromise('name', (t, resolve, reject) => { ... }) for async stream-based tests.
   • Use t.deepEqual(), t.equal(), t.ok() for assertions.
4. Test file naming must match test-*.mjs (ESM), test-*.cjs (CJS), or test-*.mts (TS) — the tape6 config in package.json globs for these patterns. // turbo
5. Run the full test suite to verify: npm test
6. Run TypeScript type checking: npm run ts-check
7. Report results and any failures.

stream-csv-as-json conventions

• Test file naming: test-*.mjs (ESM), test-*.cjs (CJS), test-*.mts (TS) in tests/.
• ESM tests use import, CJS tests use require().
• test.asPromise() for stream-based async tests with resolve/reject callbacks.
• Common pattern: create a pipeline with chain([readString(input), component()]), collect output in an array via 'data' events, verify on 'end' with t.deepEqual().
• Use readString helper from tests/read-string.mjs for testing chunked input at configurable chunk sizes.
• Source modules are in src/: parser.js, as-objects.js, stringer.js, index.js, utils/with-parser.js.
