testAsync(
testFn: (tc: TestCase) => void | Promise<void>,
settings?: Partial<Settings>,
): Promise<void>
Run a property-based test with an asynchronous test body.

Returns a Promise<void> that resolves when the test completes and rejects if any test case fails.
Parameters
- testFn: (tc: TestCase) => void | Promise<void>
- Optionalsettings: Partial<Settings>
Returns Promise<void>
Example
```
import { test } from 'vitest';
import * as hegel from 'hegel';
import * as gs from 'hegel/generators';

test('my async test', () =>
  hegel.testAsync(async (tc) => {
    const x = tc.draw(gs.integers());
    const result = await someAsyncOperation(x);
    expect(result).toEqual(expected(x));
  }),
);
```
