  assertDefined 
} from '@natiwo/testing';

// Mocks
const mockFn = createMock((x: number) => x * 2);
mockFn(5); // Returns 10
console.log(mockFn.calls); // [[5]]

// Fixtures
const user = createUserFixture({ name: 'John' });

// Builders

  .with({ email: '[email protected]' })
  .build();

// Assertions
