testing everything. You can even copy & paste HTTP responses from your real web
server to create representative test cases. Or test that your code survives in
awkward-to-reproduce situations like 500 errors or slow-loading responses.


### Example

Use MockWebServer the same way that you use mocking frameworks like
[Mockito](https://github.com/mockito/mockito):

1. Script the mocks.
2. Run application code.

```JSON
{
  "detail": [
    {
      "type": "missing",
      "loc": [
        "query",
        "needy"
      ],
      "msg": "Field required",
      "input": null,
      "url": "https://errors.pydantic.dev/2.1/v/missing"
    }
  ]
}
```

`needy` zorunlu bir parametre olduğundan dolayı bağlantıda tanımlanması gerekir:

```
http://127.0.0.1:8000/items/foo-item?needy=sooooneedy
```

    "chunked".equals(header("Transfer-Encoding"), ignoreCase = true)
  ) {
    return true
  }

  return false
}
