/// tip

If you want to call `async` functions in your tests apart from sending requests to your FastAPI application (e.g. asynchronous database functions), have a look at the [Async Tests](../advanced/async-tests.md) in the advanced tutorial.

///

## Separating tests { #separating-tests }

In a real application, you probably would have your tests in a different file.

1. **Human review, human decisions.** A real human developer will review your PR, provide feedback, and decide whether to accept or reject it. We may use AI tools to help us understand your changes, but a human is always in charge.
2. **Thoughtful, honest feedback.** We will consider every contribution on its merits, regardless of whether AI was used. We may not respond quickly—our review queue is long—but we will tell you clearly what works, what needs to change, and why.

In this case, `item_id` is declared to be an `int`.

/// check

This will give you editor support inside of your function, with error checks, completion, etc.

If you run this example and open your browser at [http://127.0.0.1:8000/items/3](http://127.0.0.1:8000/items/3), you will see a response of:

```JSON

#!/usr/bin/env/python

import boto3
from botocore.client import Config

s3 = boto3.client('s3',
        endpoint_url='http://localhost:9000',
        aws_access_key_id='YOUR-ACCESSKEYID',
        aws_secret_access_key='YOUR-SECRETACCESSKEY',
        config=Config(signature_version='s3v4'),
        region_name='us-east-1')


def _add_header(request, **kwargs):
    request.headers.add_header('x-minio-extract', 'true')

var AWS = require('aws-sdk');

var s3  = new AWS.S3({
    accessKeyId: 'YOUR-ACCESSKEYID' ,
    secretAccessKey: 'YOUR-SECRETACCESSKEY' ,
    endpoint: 'http://127.0.0.1:9000' ,
    s3ForcePathStyle: true,
    signatureVersion: 'v4'
});

// List all contents stored in the zip archive
s3.listObjectsV2({Bucket : 'your-bucket', Prefix: 'path/to/file.zip/'}).
    on('build', function(req) { req.httpRequest.headers['X-Minio-Extract'] = 'true'; }).

FastAPI will use this return type to:

* **Validate** the returned data.
    * If the data is invalid (e.g. you are missing a field), it means that *your* app code is broken, not returning what it should, and it will return a server error instead of returning incorrect data. This way you and your clients can be certain that they will receive the data and the data shape expected.
* Add a **JSON Schema** for the response, in the OpenAPI *path operation*.

Directory for ReplaceSchema task

replace-schema-*.sql:
DDL statements for creation of your schema.
You should write your own DDL statements in this file.
(A SQL separator is semicolon ";")

take-finally-*.sql:
SQL statements for check loaded data (or DDL after data loading)
You should write your own SQL statements in this file.
(basically same specifications as replace-schema.sql)

The "data" directory is for data loading like this:

At a minimum, that file should contain either a full sentence or a TODO,
ideally referring to a person with the responsibility to complete the note.

If your CL addresses an accepted proposal, mention the proposal issue number in
your release note in the form `/issue/NUMBER`. A link to the issue in the text
will have this form (see below). If you don't want to mention the issue in the
text, add it as a comment:
```

#     }

# *The line that starts with '#' means comment-out.
