Specific security vs. connectivity decisions are implemented by [ConnectionSpec](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-connection-spec/). OkHttp includes four built-in connection specs:

 * `RESTRICTED_TLS` is a secure configuration, intended to meet stricter compliance requirements.
 * `MODERN_TLS` is a secure configuration that connects to modern HTTPS servers.

import org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement

/**
 * Models the contents of a `Sec-WebSocket-Extensions` response header. OkHttp honors one extension
 * `permessage-deflate` and four parameters, `client_max_window_bits`, `client_no_context_takeover`,
 * `server_max_window_bits`, and `server_no_context_takeover`.
 *
 * Typically this will look like one of the following:
 *
 * ```

      dest[4] = upperHexDigits[0x8 | (cp & 0x3)];
      cp >>>= 2;
      dest[2] = upperHexDigits[cp];
      return dest;
    } else if (cp <= 0x10ffff) {
      char[] dest = new char[12];
      // Four byte UTF-8 characters [cp >= 0xffff && cp <= 0x10ffff]
      // Start with "%F-%--%--%--" and fill in the blanks
      dest[0] = '%';
      dest[1] = 'F';
      dest[3] = '%';
      dest[6] = '%';

Nun erweitern wir dieses Beispiel und fügen weitere Details hinzu, um zu sehen, wie verschiedene Teile getestet werden.

### Erweiterte **FastAPI**-Anwendungsdatei

Fahren wir mit der gleichen Dateistruktur wie zuvor fort:

```
.
├── app
│   ├── __init__.py
│   ├── main.py
│   └── test_main.py
```

Nehmen wir an, dass die Datei `main.py` mit Ihrer **FastAPI**-Anwendung jetzt einige andere **Pfadoperationen** hat.

    Iterator<String> iterator = asList("one", "two", "three", "four", "five").iterator();
    IllegalArgumentException expected =
        assertThrows(IllegalArgumentException.class, () -> getOnlyElement(iterator));
    assertThat(expected)
        .hasMessageThat()
        .isEqualTo("expected one element but was: <one, two, three, four, five>");
  }

  public void testGetOnlyElement_noDefault_moreThanFiveElements() {

    Iterator<String> iterator = asList("one", "two", "three", "four", "five").iterator();
    IllegalArgumentException expected =
        assertThrows(IllegalArgumentException.class, () -> getOnlyElement(iterator));
    assertThat(expected)
        .hasMessageThat()
        .isEqualTo("expected one element but was: <one, two, three, four, five>");
  }

  public void testGetOnlyElement_noDefault_moreThanFiveElements() {

        }
    }

        void shouldDefineExactlyFourPublicMethods() {

# Extramodelle

Fahren wir beim letzten Beispiel fort. Es gibt normalerweise mehrere zusammengehörende Modelle.

Insbesondere Benutzermodelle, denn:

* Das **hereinkommende Modell** sollte ein Passwort haben können.
* Das **herausgehende Modell** sollte kein Passwort haben.
