### Typical Exporter Test Setup

Source: https://github.com/fhir/sushi/blob/master/AGENTS.md

Sets up the testing environment by loading FHIR definitions and initializing necessary components for exporter tests. Ensure loggerSpy is reset in beforeEach.

```typescript
beforeAll(async () => {
  defs = await getTestFHIRDefinitions(true, testDefsPath('r4-definitions'));
});
beforeEach(() => {
  loggerSpy.reset();
  doc = new FSHDocument('fileName');
  const input = new FSHTank([doc], minimalConfig);
  pkg = new Package(input.config);
  const fisher = new TestFisher(input, defs, pkg);
  exporter = new StructureDefinitionExporter(input, pkg, fisher);
});
```

--------------------------------

### Run SUSHI Regression Test via NPM

Source: https://github.com/fhir/sushi/blob/master/README.md

Execute the regression script using npm, passing arguments after '--'. This example uses lookback days and repository count.

```sh
$ npm run regression -- -l 30 -c 50
```
