3. Make sure the file with accepted changes is sorted.\
Use the `./gradlew :architecture-test:sortAcceptedApiChanges` task to sort the file.

4. Validate your changes before committing.\
Run the `./gradlew sanityCheck` task again to make sure there are no more errors.

#### Filtering changes by severity

      "FINE: Q10000 scheduled after 100 µs: task",
      "FINE: Q10000 starting              : task",
      "FINE: Q10000 run again after  50 µs: task",
      "FINE: Q10000 finished run in   0 µs: task",
      "FINE: Q10000 starting              : task",
      "FINE: Q10000 run again after 150 µs: task",

  /** The coordinator task if it's waiting, and how it will resume. Guarded by [TaskRunner.lock]. */

I'll show you some concrete examples in the next chapters.

Then the next concepts to consider are all about the program running your actual API (e.g. Uvicorn).

## Program and Process

We will talk a lot about the running "**process**", so it's useful to have clarity about what it means, and what's the difference with the word "**program**".

### What is a Program

* Fortgeschrittenere (aber ebenso einfache) Techniken zur Deklaration **tief verschachtelter JSON-Modelle** (dank Pydantic).
* **GraphQL** Integration mit <a href="https://strawberry.rocks" class="external-link" target="_blank">Strawberry</a> und anderen Bibliotheken.
* Viele zusätzliche Funktionen (dank Starlette) wie:
    * **WebSockets**
    * extrem einfache Tests auf Basis von `httpx` und `pytest`
    * **CORS**

### Podsumowanie

Podsumowując, musiałeś zadeklarować typy parametrów, treści żądania (body) itp. tylko **raz**, i są one dostępne jako parametry funkcji.

Robisz to tak samo jak ze standardowymi typami w Pythonie.

Nie musisz sie uczyć żadnej nowej składni, metod lub klas ze specyficznych bibliotek itp.

Po prostu standardowy **Python**.

Na przykład, dla danych typu `int`:

      "coverage" : {
        "per_commit" : [ "linux", "windows", "macOs" ]
      }
    } ]
  }, {
    "testId" : "org.gradle.performance.regression.android.RealLifeAndroidBuildPerformanceTest.calculate task graph with test finalizer",
    "groups" : [ {
      "testProject" : "largeAndroidBuild",
      "coverage" : {
        "per_commit" : [ "linux" ]
      }
    } ]
  }, {

### En résumé

En résumé, vous déclarez **une fois** les types de paramètres, <abbr title="en anglais : body">le corps</abbr>  de la requête, etc. en tant que paramètres de fonction.

Vous faites cela avec les types Python standard modernes.

Vous n'avez pas à apprendre une nouvelle syntaxe, les méthodes ou les classes d'une bibliothèque spécifique, etc.

When you pass the file to `fastapi run` it will detect automatically that it is a single file and not part of a package and will know how to import it and serve your FastAPI app. 😎

## Deployment Concepts

Let's talk again about some of the same [Deployment Concepts](concepts.md){.internal-link target=_blank} in terms of containers.
