在输出中，会有一行信息像下面这样：

```hl_lines="4"

## Introduction {#intro}

Go's emphasis on backwards compatibility is one of its key strengths.
There are, however, times when we cannot maintain complete compatibility.
If code depends on buggy (including insecure) behavior,
then fixing the bug will break that code.
New features can also have similar impacts:
enabling the HTTP/2 use by the HTTP client broke programs

		int64(len(completeBytes)), bytes.NewReader(completeBytes), s.accessKey, s.secretKey, s.signer)
	c.Assert(err, nil)
	// Execute the complete multipart request.
	response, err = s.client.Do(request)
	c.Assert(err, nil)
	// verify whether complete multipart was successful.
	c.Assert(response.StatusCode, http.StatusOK)
	var parts []CompletePart
	for _, part := range completeUploads.Parts {

    assertThat(log).containsExactly(
      "red:starting@0",
      "blue:starting@0",
    )
    assertThat(taskFaker.executeCallCount).isEqualTo(2)

    // Advance time until the tasks complete.
    taskFaker.advanceUntil(100.µs)
    assertThat(log).containsExactly(
      "red:starting@0",
      "blue:starting@0",
      "red:finishing@100000",
      "blue:finishing@100000",
    )

/// tip

But it is still recommended to use the ideas above, using multiple classes, instead of these parameters.

This is because the JSON Schema generated in your app's OpenAPI (and the docs) will still be the one for the complete model, even if you use `response_model_include` or `response_model_exclude` to omit some attributes.

This also applies to `response_model_by_alias` that works similarly.
