Better document testing

Hi, neither the docs or code examples mention how to set up tests - which I think is important for any non trivial function.

I currently hook up my tests like this:

from flask import testing
import pytest
from functions_framework import create_app
import pathlib


@pytest.fixture
def client() -> testing.Client:
    target = "function_name"
    source = pathlib.Path(__file__).parent.parent / "main.py"

    with create_app(target, str(source)).test_client() as client:
        yield client

def test_something(client: testing.Client):
    rv = client.post('/', data="no json")
    assert rv.status_code == 400

this assumes that the test file is inside a test folder.

I think it is also functions framework documentation - the framework abstracts away some details and that makes it difficult to get integration test up and running.

The entry for integration testing is only for node currently: https://cloud.google.com/functions/docs/testing/test-http#integration_tests

I would suggest adding a paragraph detailing how to set up IT tests for this framework in this repo, e.g. showing how to get the testing.Client and how to work with it. That way, people don’t have to know the internals of flask to work with the functions framework.

@ChristianSauer thanks again for filing this issue. Seeing as we’ve added a sample in Python and there hasn’t been much activity on this since then, I’m going to close the issue as fixed.

Please feel free to reopen if this is not in fact fixed, or file a new issue if you have other concerns. Thanks! 🙂
