## 官方指南 { #official-guide }

Pydantic 提供從 v1 遷移到 v2 的官方[遷移指南](https://docs.pydantic.dev/latest/migration/)。

其中包含變更內容、驗證如何更正確且更嚴格、可能的注意事項等。

你可以先閱讀以更好理解具體變更。

## 測試 { #tests }

確保你的應用有[測試](../tutorial/testing.md)，並在 CI（持續整合）上執行。

如此一來，你可以升級後確認一切仍如預期運作。

## `bump-pydantic` { #bump-pydantic }

在許多情況下，若你使用的是未自訂的標準 Pydantic 模型，多數遷移步驟都能自動化完成。

Your unit tests might move the `server` into a field so you can shut it down
from your test's `tearDown()`.

### API

#### MockResponse

Mock responses default to an empty response body and a `200` status code.

      fail<Any>()
    } catch (ioe: IOException) {
      assertThat(ioe).hasMessage("google.com")
      assertThat(ioe.cause!!).isInstanceOf<EOFException>()
    }
  }

  // TODO GET preferred order - with tests to confirm this
  // 1. successful fresh cached GET response
  // 2. unsuccessful (404, 500) fresh cached GET response
  // 3. successful network response
  // 4. successful stale cached GET response

@ExtendWith(MockitoExtension.class)
class HandlerTest {

    @Mock
    CIFSContext mockCtx;

    @Mock
    Configuration mockCfg;

    // Provides a fresh handler instance for tests
    private Handler newHandler() {
        return new Handler();
    }

    // Provides a handler wired with a mocked CIFSContext
    private Handler newHandlerWith(CIFSContext ctx) {
        return new Handler(ctx);
