I would suggest:
Change `function guessInputFormat(sampleData: string[]): InputFormat {` to
`export function guessInputFormat(sampleData: string[]): InputFormat {`
Also in `ingestion-spec.spec.ts` change `import { cleanSpec, downgradeSpec,
upgradeSpec } from './ingestion-spec';` to `import { cleanSpec, downgradeSpec,
guessInputFormat, upgradeSpec } from './ingestion-spec';`
And add this just before the final `});` of the file:
```
describe('guessInputFormat', () => {
it('works for parquet', () => {
expect(guessInputFormat(['PAR1lol']).type).toEqual('parquet');
});
it('works for orc', () => {
expect(guessInputFormat(['ORClol']).type).toEqual('orc');
});
it('works for AVRO', () => {
expect(guessInputFormat(['Obj\x01lol']).type).toEqual('avro_ocf');
expect(guessInputFormat(['Obj1lol']).type).toEqual('regex');
});
it('works for JSON', () => {
expect(guessInputFormat(['{"a":1}']).type).toEqual('json');
});
it('works for TSV', () => {
expect(guessInputFormat(['A\tB\tX\tY']).type).toEqual('tsv');
});
it('works for CSV', () => {
expect(guessInputFormat(['A,B,X,Y']).type).toEqual('csv');
});
it('works for regex', () => {
expect(guessInputFormat(['A|B|X|Y']).type).toEqual('regex');
});
});
```
That should do it.
