Hi there, thanks for this project.

I am currently trying to integrate it in the tests of my nest project, but cant get it to work properly.

When I try to get these fixtures

entity: Customer
items:
  customer1:
    company: '{{name.firstName}}'
    customerNumber: '{{datatype.number}}'
    baseFeeType: 'none'
    devices:
      - device1
  customer2:
    company: '{{name.firstName}}'
    customerNumber: '{{datatype.number}}'
    baseFeeType: 'monthly'
    devices:
      - device2
  customer3:
    company: '{{name.firstName}}'
    customerNumber: '{{datatype.number}}'
    baseFeeType: 'quarterly'
    devices:
      - device3
  customer4:
    company: '{{name.firstName}}'
    customerNumber: '{{datatype.number}}'
    baseFeeType: 'annually'
    devices:
      - device4

persisted to my test database with this code:

describe('BillingService', () => {
  let service: BillingService;

  beforeEach(async () => {
    const module: TestingModule = await Test.createTestingModule({
      imports: [
        SessionModule,
        TypeOrmModule.forRoot(testConfig),
        TypeOrmModule.forFeature([Bill]),
      ],
      providers: [BillingService],
    })
      .overrideProvider(TwilioService)
      .useValue({})
      .compile();

    const app = module.createNestApplication();
    await app.init();
    service = module.get<BillingService>(BillingService);

    const loader = new Loader();
    loader.load(__dirname + '/fixtures');
    const resolver = new Resolver();
    const fixtures = resolver.resolve(loader.fixtureConfigs);

    const connection: Connection = module.get(Connection);
    const builder = new Builder(connection, new Parser());

    for (const fixture of fixturesIterator(fixtures)) {
      const entity = await builder.build(fixture);
      console.log(entity);
      await getRepository(entity.constructor.name).save(entity);
    }
  });

  it('should be defined', () => {
    expect(service).toBeDefined();
  });
});

the console.log() always prints Customer {}, which is the correct type of entity, but empty, meaning it does not contain any of the fields mentioned in the fixture yaml, which again crashes the save call, because the database restrictions are not fullfilled.

Any suggestions what I can try to make it work?

for me this was having a @Exclude() annotation from class-transformer in the top of the entity.

@wodka this seems to help, although I would like to be able to still use the @Exclude annotation.
