flask application code:
# main.py
from flask import Flask, Response
app = Flask(__name__)
@app.route("/", methods=["POST"])
def post_example():
return Response("aaa")
and this is my testing code:
# e2e.py
from main import app
test_client = app.test_client()
def test_flask_api_call():
response = test_client.post("/", {"a": "b"})
pass
I keep receiving:
raise ValueError("unknown url type: %r" % self.full_url)
ValueError: unknown url type: '://%7B%27a%27:%20%27b%27%7D/'
The problem is on the post method call. You have to name your data arguments client.post("/", data={"a": "b"}), if it's not the case it is considered as a part of the URL.
urllib.parse.quote("/" + str({"a": "b"}))
# '/%7B%27a%27%3A%20%27b%27%7D'
Here is the test code rewritten to define a fixture for the client initialization. More info on testing flask application on the official doc.
import pytest
from main import app
@pytest.fixture(scope="module")
def client():
with app.test_client() as client:
yield client
def test_flask_api_call(client):
response = client.post("/", data={"a": "b"})
assert response.status_code == 200, f"Got bad status code {response.status_code}"
