有了測試之後，你就可以將 **FastAPI** 升級到較新的版本，並透過執行測試來確保所有程式碼都能正確運作。

如果一切正常，或在完成必要調整且所有測試通過之後，就可以把你的 `fastapi` 鎖定到該新的版本。

## 關於 Starlette { #about-starlette }

你不應鎖定 `starlette` 的版本。

不同的 **FastAPI** 版本會使用特定較新的 Starlette 版本。

因此，你可以直接讓 **FastAPI** 使用正確的 Starlette 版本。

## 關於 Pydantic { #about-pydantic }

Pydantic 在其測試中涵蓋了 **FastAPI** 的測試，因此 Pydantic 的新版本（高於 `1.0.0`）一律與 FastAPI 相容。

你可以將 Pydantic 鎖定到任何高於 `1.0.0`、適合你的版本。

例如：

package org.apache.maven.building;

/**
 * Describes a problem that was encountered during settings building. A problem can either be an exception that was
 * thrown or a simple string message. In addition, a problem carries a hint about its source, e.g. the settings file
 * that exhibits the problem.
 *
 * @deprecated since 4.0.0, use {@link org.apache.maven.api.services} instead
 */
@Deprecated(since = "4.0.0")
public interface Problem {

    /**

* etc.

It can be convenient to quickly access HTTP (and WebSocket) status codes in your app, using autocompletion for the name without having to remember the integer status codes by memory.

Read more about it in the [FastAPI docs about Response Status Code](https://fastapi.tiangolo.com/tutorial/response-status-code/).

## Example

```python
from fastapi import FastAPI, status

app = FastAPI()

P = ParamSpec("P")


class BackgroundTasks(StarletteBackgroundTasks):
    """
    A collection of background tasks that will be called after a response has been
    sent to the client.

    Read more about it in the
    [FastAPI docs for Background Tasks](https://fastapi.tiangolo.com/tutorial/background-tasks/).

    ## Example

    ```python
    from fastapi import BackgroundTasks, FastAPI

    app = FastAPI()

모든 것이 동작하거나 필요한 변경을 한 뒤 모든 테스트가 통과한다면, `fastapi`를 그 새로운 최신 버전으로 고정할 수 있습니다.

## Starlette에 대해 { #about-starlette }

`starlette`의 버전은 고정하지 않는 것이 좋습니다.

서로 다른 **FastAPI** 버전은 Starlette의 특정한 더 새로운 버전을 사용하게 됩니다.

따라서 **FastAPI**가 올바른 Starlette 버전을 사용하도록 그냥 두면 됩니다.

## Pydantic에 대해 { #about-pydantic }

Pydantic은 자체 테스트에 **FastAPI**에 대한 테스트도 포함하고 있으므로, Pydantic의 새 버전(`1.0.0` 초과)은 항상 FastAPI와 호환됩니다.

@Deprecated(since = "4.0.0")

one (even if it was for a different project), you probably don't need to do it
again.

## Building and Testing

The most reliable way to build and test Guava is:

```shell
./mvnw clean install
```

      Spliterator<T> fromSpliterator, Predicate<? super T> predicate) {
    checkNotNull(fromSpliterator);
    checkNotNull(predicate);
    @IgnoreJRERequirement // see earlier comment about redundancy
    final class Splitr implements Spliterator<T>, Consumer<T> {
      @Nullable T holder = null;

      @Override
      public void accept(@ParametricNullness T t) {
        this.holder = t;
      }
