test-e2e-functions.sh

#!/bin/bash
# Script to run the gated Azure Functions host E2E tests.
#
# This mirrors scripts/test-e2e-azuremanaged.sh. The suite launches a real
# Azure Functions host ("func start") for test/e2e-functions/test-app, backed by
# Azurite (the local Azure Storage emulator), and drives it over HTTP.
#
# The test-app depends on the PUBLISHED durable-functions / @azure/functions
# packages, so it installs and builds without any in-repo package build.
#
# Prerequisites (the suite SKIPS cleanly if any are missing):
#   - Azure Functions Core Tools ('func') v4 on PATH
#   - Azurite reachable on 127.0.0.1:10000 (started here if the 'azurite' CLI is
#     installed and the port is free)
