[-I] [-b] [-p] [-n NUMBER] [-v]
app [url]

positional arguments:

application/json'
-d DATA, --data DATA request body data, e.g. '{"msg":"hello"}', 'msg=hello'
-F MULTIPART, --form MULTIPART
specify HTTP multipart POST data, e.g. name=value or
name=@file
-I, --head show status and headers only
-b, --benchmark issue a number of requests through repeated iterations
(reports throughtput and average call time)
-p, --profile prints out a report of top 10 functions ordered by
internal time, saves to 'stats.cprof' file
-n NUMBER a number of requests to issue (default 100K)
-v, --verbose make the operation more talkative

Examples
example.py:
START = {
"type": "http.response.start",
"status": 200,
"headers": [
(b"content-length", b"13"),
(b"content-type", b"text/html; charset=utf-8"),
],
}

BODY1 = {"type": "http.response.body", "body": b"Hello"}
BODY2 = {"type": "http.response.body", "body": b", world!"}

async def app(scope, receive, send) -> None:
await send(START)
await send(BODY1)
await send(BODY2)

Then run the examples:
asgi-cli example:app prints response body:
Hello, world!

asgi-cli -v example:app pretty prints scope and sent messages:
{'scope': {'asgi': {'spec_version': '2.1', 'version': '3.0'},
'client': ('127.0.0.1', 49327),
'headers': [(b'accept', b'*/*'),
(b'user-agent', b'asgi-cli/0.0.1'),
(b'host', b'127.0.0.1:8000')],
'http_version': '1.1',
'method': 'GET',
'path': '/',
'query_string': b'',
'raw_path': b'/',
'root_path': '',
'scheme': 'http',
'server': ('127.0.0.1', 8000),
'type': 'http'}}
{'message': {'headers': [(b'content-length', b'13'),
(b'content-type', b'text/html; charset=utf-8')],
'status': 200,
'type': 'http.response.start'}}
{'message': {'body': b'Hello', 'type': 'http.response.body'}}
{'message': {'body': b', world!', 'type': 'http.response.body'}}

asgi-cli -b example:app shows execution stats (runs in 3 iterations, for each iteration displays requests per second and an average call time):
#1 => 477.74K, 2.09μs
#2 => 438.12K, 2.28μs
#3 => 446.90K, 2.24μs
