```

1. Copie o arquivo `main.py` para o diretório `/code` diretamente (sem nenhum diretório `./app`).

2. Execute o Uvicorn e diga a ele para importar o objeto `app` de `main` (em vez de importar de `app.main`).

Então ajuste o comando Uvicorn para usar o novo módulo `main` em vez de `app.main` para importar o objeto FastAPI `app`.

## Conceitos de Implantação

          // In the case of a concurrent remove, we might observe a zero value, which means another
          // thread is about to remove (element, existingCounter) from the map. Rather than wait,
          // we can just do that work here.
          AtomicInteger newCounter = new AtomicInteger(occurrences);
          if ((countMap.putIfAbsent(element, newCounter) == null)
              || countMap.replace(element, existingCounter, newCounter)) {

But the rest of the session code is more or less the same, we just copy it.

```

!!! tip
    You could reduce duplication in that code by putting it in a function and using it from both `database.py` and `tests/test_sql_app.py`.

    For simplicity and to focus on the specific testing code, we are just copying it.

## Create the database

    val call = client.newCall(request1)
    assertFailsWith<IllegalStateException> {
      call.execute()
    }.also { expected ->
      assertThat(expected.message)
        .isEqualTo("Timeouts can't be adjusted in a network interceptor")
    }
  }

  @Test
  fun networkInterceptorCannotChangeWriteTimeout() {
    addInterceptor(true) { chain: Interceptor.Chain ->
      chain.withWriteTimeout(
        100,

### Just Modern Python

It's all based on standard **Python type** declarations (thanks to Pydantic). No new syntax to learn. Just standard modern Python.

Do you want to just have a `str`? Or just a `dict`? Or a database class model instance directly? It all works the same way.

You actually don't have users that log in to your application but robots, bots, or other systems, that have just an access token? Again, it all works the same.

Each "scope" is just a string (without spaces).

They are normally used to declare specific security permissions, for example:

* `users:read` or `users:write` are common examples.
* `instagram_basic` is used by Facebook / Instagram.
* `https://www.googleapis.com/auth/drive` is used by Google.

!!! info
    In OAuth2 a "scope" is just a string that declares a specific permission required.

- Now click on the new project you just created. The URL should be `https://builds.gradle.org/admin/editProject.html?projectId=Gradle_<MyTestBranch>`.
- Click `Versioned Settings` on the left sidebar.
  - Select `Synchronization enabled` - `use settings from VCS` - `MyNewVcsRoot`(the one you just created) - `Settings format: Kotlin`, then `Apply`.

But this way we can focus on how the **Dependency Injection** system works.

### Create a dependency, or "dependable"

Let's first focus on the dependency.

It is just a function that can take all the same parameters that a *path operation function* can take:

!!! note "Technical Details"
    You could also use `from starlette.testclient import TestClient`.

    **FastAPI** provides the same `starlette.testclient` as `fastapi.testclient` just as a convenience for you, the developer. But it comes directly from Starlette.
