Now we create a `HeroCreate` model, this is the one that will **validate** the data from the clients.

It has the same fields as `HeroBase`, and it also has `secret_name`.

Now, when the clients **create a new hero**, they will send the `secret_name`, it will be stored in the database, but those secret names won't be returned in the API to the clients.

# Test Client - `TestClient`

You can use the `TestClient` class to test FastAPI applications without creating an actual HTTP and socket connection, just communicating directly with the FastAPI code.

Read more about it in the [FastAPI docs for Testing](https://fastapi.tiangolo.com/tutorial/testing/).

You can import it directly from `fastapi.testclient`:

```python
from fastapi.testclient import TestClient
```

	u, err := url.Parse(endpoint)
	if err != nil {
		return nil, err
	}

	secure := strings.EqualFold(u.Scheme, "https")
	transport, err := minio.DefaultTransport(secure)
	if err != nil {
		return nil, err
	}
	if insecure {
		// skip TLS verification
		transport.TLSClientConfig.InsecureSkipVerify = true
	}

	clnt, err := minio.New(u.Host, &minio.Options{
