gabbi in the browser

1. start a CORS-enabled HTTP server at http://localhost:8000 (see below)
2. visit Pyodide REPL
3. paste setup.py contents into the REPL
4. paste test_case.py contents into the REPL

HTTP Server

You might use nc -l 8000 and manually respond to the incoming request:

HTTP/1.1 200 OK
Content-Type: text/plain
Access-Control-Allow-Origin: *

hello world

setup.py

import micropip
import sys

from http import client


def create_module(name):
    module_cls = type(sys) # cf. https://github.com/brettlangdon/virtualmod
    mod = module_cls(name)
    sys.modules[name] = mod
    return mod


class HTTPSConnection(client.HTTPConnection):
    pass


# mock `HTTPSConnection` because OpenSSL functionality is unavailable in Pyodide
setattr(client, "HTTPSConnection", HTTPSConnection)

# mock `jsonpath-rw-ext` because there's no wheel distribution for `jsonpath-rw`
jsonpath = create_module("jsonpath_rw_ext")
parser = create_module("jsonpath_rw_ext.parser")
setattr(parser, "ExtentedJsonPathParser",
        lambda *args: print("mocking JSONPath parser"))

# mock `colorama` to suppress escape sequences
colorama = create_module("colorama")
setattr(colorama, "init",
        lambda *args: print("mocking colorama"))

# manually install dependencies due to the above
await micropip.install("gabbi", deps=False)
await micropip.install("pytest")
await micropip.install("pyyaml")
await micropip.install("wsgi_intercept")
await micropip.install("certifi")
await micropip.install("urllib3")
print(micropip.list())
