> Requests is one of the most downloaded Python packages of all time

The way you use it is very simple. For example, to do a `GET` request, you would write:

```Python
response = requests.get("http://example.com/some/url")
```

The FastAPI counterpart API *path operation* could look like:

```Python hl_lines="1"
@app.get("/some/url")
def read_url():

    while (!body.exhausted()) {
      val chunkSize = minOf(body.size, maxChunkSize.toLong())
      bytesOut.writeHexadecimalUnsignedLong(chunkSize)
      bytesOut.writeUtf8("\r\n")
      bytesOut.write(body, chunkSize)
      bytesOut.writeUtf8("\r\n")
    }
    bytesOut.writeUtf8("0\r\n") // Last chunk. Trailers follow!
    this.body = bytesOut
  }

  fun setChunkedBody(
    body: String,

# Async Tests { #async-tests }

You have already seen how to test your **FastAPI** applications using the provided `TestClient`. Up to now, you have only seen how to write synchronous tests, without using `async` functions.
