Pact: Error when trying to setup mock provider - pact

Question

I'm trying to write my first Pact-python test using pytest, Could someone please tell me what's wrong with my code?
import unittest
import requests
import json
import pytest
import atexit
from pact import Consumer, Provider
pact = Consumer('Consumer').has_pact_with(Provider('Provider'), host_name='mockservice', port=8080)
pact.start_service()
atexit.register(pact.stop_service)
class InterviewDetails(unittest.TestCase):
def test_candidate_report_api(self):
candidate_report_payload = {}
resp = requests.post("http://localhost:1234/users/",data=json.dumps(candidate_report_payload))
response = json.loads(resp.text)
return response
#pytest.mark.health1
def test_candidate_report(self):
expected = {}
(pact.given('Comment')
.upon_receiving('comment')
.with_request(method='POST', path="http://localhost:1234/users/", headers={})
.will_respond_with(200, body=expected))
with pact:
pact.setup()
result = self.test_candidate_report_api()
self.assertEqual(result, expected)
pact.verify()
The error from stacktrace:
AttributeError: module 'pact' has no attribute 'Like'

Can you please confirm you're using pact-python from https://github.com/pact-foundation/pact-python/ (and not pactman, a project that is not maintained by the Pact Foundation)?
It might be related to the way you have setup your test?
Here is an example project you can use for reference: https://github.com/pactflow/example-consumer-python/
Relevant test code:
"""pact test for product service client"""
import json
import logging
import os
import requests
from requests.auth import HTTPBasicAuth
import pytest
from pact import Consumer, Like, Provider, Term, Format
from src.consumer import ProductConsumer
log = logging.getLogger(__name__)
logging.basicConfig(level=logging.INFO)
print(Format().__dict__)
PACT_MOCK_HOST = 'localhost'
PACT_MOCK_PORT = 1234
PACT_DIR = os.path.dirname(os.path.realpath(__file__))
#pytest.fixture
def consumer():
return ProductConsumer(
'http://{host}:{port}'
.format(host=PACT_MOCK_HOST, port=PACT_MOCK_PORT)
)
#pytest.fixture(scope='session')
def pact(request):
pact = Consumer('pactflow-example-consumer-python').has_pact_with(
Provider('pactflow-example-provider-python'), host_name=PACT_MOCK_HOST, port=PACT_MOCK_PORT,
pact_dir="./pacts", log_dir="./logs")
try:
print('start service')
pact.start_service()
yield pact
finally:
print('stop service')
pact.stop_service()
def test_get_product(pact, consumer):
expected = {
'id': "27",
'name': 'Margharita',
'type': 'Pizza'
}
(pact
.given('a product with ID 10 exists')
.upon_receiving('a request to get a product')
.with_request('GET', '/product/10')
.will_respond_with(200, body=Like(expected)))
with pact:
user = consumer.get_product('10')
assert user.name == 'Margharita'
