3. Kopiere die Datei mit den Paketanforderungen in das Verzeichnis `/code`.

    Kopieren Sie zuerst **nur** die Datei mit den Anforderungen, nicht den Rest des Codes.

    Da sich diese Datei **nicht oft ändert**, erkennt Docker das und verwendet den **Cache** für diesen Schritt, wodurch der Cache auch für den nächsten Schritt aktiviert wird.

We will create a FastAPI **dependency** with `yield` that will provide a new `Session` for each request. This is what ensures that we use a single session per request. 🤓

Then we create an `Annotated` dependency `SessionDep` to simplify the rest of the code that will use this dependency.

 * {@code Nullable}, {@code CheckForNull}, {@code NullableType}, or {@code NullableDecl}.

 * <p>The tested methods and constructors are invoked -- each time with one parameter being null and
 * the rest not null -- and the test fails if no expected exception is thrown. {@code

  - [Action Required Before Upgrading](#action-required-before-upgrading)
- [optionally, remove the old secret](#optionally-remove-the-old-secret)

The important thing to remember is that **the first *type parameter*** you pass to `Annotated` is the **actual type**. The rest, is just metadata for other tools.

For now, you just need to know that `Annotated` exists, and that it's standard Python. 😎

Later you will see how **powerful** it can be.
