我正在測驗模塊 match_view.py 中的一個函式（下）
from dbaccess.repository import bulk_update_zingr_id, bulk_insert_ingredients_matching_table
from services.matching_ingr_zingr import ingr_zing_match_mult_search
from services.FileStorage import dumpModel
from flask import Blueprint, request
from datetime import date
import pandas as pd
import logging
import time
match = Blueprint("match", __name__)
@match.route("/", methods=['GET', 'POST'], strict_slashes=False)
def index():
if request.method == 'POST':
logging.warning(""" RODAR O ELASTICSEARCH PARA INGREDIENTES ZAPLY ANTES DE RODAR O MATCHING""")
ingredients_list = request.get_json()
start = time.time()
results, resume, payload = ingr_zing_match_mult_search(ingredients_list)
today = date.today().strftime("%b-%d-%Y")
dumpModel(results.to_dict(), f"result_table_{today}")
dumpModel(resume.to_dict(), f"resume_table_{today}")
bulk_update_zingr_id(payload)
bulk_insert_ingredients_matching_table(resume)
tot_row = len(list(set(resume['Raw_Ingred'])))
end = time.time()
tempo = round(((end - start)), 4)
logging.warning(f"O tempo para processamento da request foi de: {tempo/60} minutos, {tempo/tot_row} segundos por item para {tot_row} ingredientes.")
return payload
else:
return "Use o método POST para processar os dados."
我嘗試了兩種方式。
1o嘗試模擬函式的路徑'src.api.matching.match_view.ingr_zing_match_mult_search'（運行但不要模擬）。
test_00_api.py
import pytest
import sys, os
sys.path.append(os.path.realpath(os.path.dirname(__file__) "/src"))
def test_match_view_post_retorno_correto(client, mocker):
result_expected = {'sal a gosto': 594, '1 cebola picada': 44}
mocker.patch('src.api.matching.match_view.ingr_zing_match_mult_search',
return_value=[[], [], {'sal a gosto': 594, '1 cebola picada': 44}])
RESOURCE_URL = "/match"
resp = client.post(RESOURCE_URL, json=['sal a gosto', '1 cebola picada'])
assert resp.status_code == 200
assert result_expected in resp.get_data(as_text=True)
2o 嘗試模擬路徑 'src.api.matching.index.match_view.ingr_zing_match_mult_search' 但引發錯誤（AttributeError: <function index at 0x000001A600339DC8> 沒有屬性 'ingr_zing_match_mult_search'）。
test_00_api.py
import pytest
import sys, os
sys.path.append(os.path.realpath(os.path.dirname(__file__) "/src"))
def test_match_view_post_retorno_correto(client, mocker):
result_expected = {'sal a gosto': 594, '1 cebola picada': 44}
mocker.patch('src.api.matching.match_view.index.ingr_zing_match_mult_search',
return_value=[[], [], {'sal a gosto': 594, '1 cebola picada': 44}])
RESOURCE_URL = "/match"
resp = client.post(RESOURCE_URL, json=['sal a gosto', '1 cebola picada'])
assert resp.status_code == 200
assert result_expected in resp.get_data(as_text=True)
我的專案結構是：
src
|--- api
| |--- matching
| |--- match_view.py
|
tests
|--- test_src
|--- test_00_api.py
模擬函式ingr_zing_match_mult_search（）的正確方法是什么？
@Macintosh_89 這是我最后一次嘗試和錯誤：
from src.api.matching import match_view
import pytest
import sys, os
sys.path.append(os.path.realpath(os.path.dirname(__file__) "/src"))
def test_match_view_post_retorno_correto(mocker, client):
result_expected = {'sal a gosto': 594, '1 cebola picada': 44}
mocker.patch('src.api.matching.match_view.ingr_match_mult_search',
return_value=[[], [], {'sal a gosto': 594, '1 cebola picada': 44}])
RESOURCE_URL = "/match"
resp = client.post(RESOURCE_URL, json=['sal a gosto', '1 cebola picada'])
assert resp.status_code == 200
assert result_expected in resp.get_data(as_text=True)

4o嘗試測驗（運行但不模擬執行ingr_zing_match_mult_search（）函式）
from src.api.matching import match_view
import pytest
import sys, os
def test_match_view_post_retorno_correto(mocker, client):
result_expected = {'sal a gosto': 594, '1 cebola picada': 44}
mocker.patch('src.api.matching.match_view.ingr_zing_match_mult_search',
return_value=[[], [], {'sal a gosto': 594, '1 cebola picada': 44}])
RESOURCE_URL = "/match"
resp = client.post(RESOURCE_URL, json=['sal a gosto', '1 cebola picada'])
assert resp.status_code == 200
assert result_expected in resp.get_data(as_text=True)
uj5u.com熱心網友回復：
我認為您需要將函式本身匯入到測驗檔案中。嘗試：
from src.api.matching.match_view import ingr_zing_match_mult_search
然后修補該功能：
mocker.patch('src.api.matching.match_view.ingr_zing_match_mult_search',
return_value=[[], [], {'sal a gosto': 594, '1 cebola picada': 44}])
請參閱此處了解更多資訊。

經過許多。經過多次嘗試，我終于找到了解決方案（我將在這個答案的末尾給出解決方案）。基本上我設法運行測驗，我匯入了 index() 函式，并在 POST 方法中執行單元測驗。為此，我使用背景關系管理器激活了 test_request_context。所以我設法模擬了 de index() 中的結果（之前所有函式都經過了測驗）。然后測驗運行并覆寫所需的所有行。我真的不知道這是否是執行單元測驗的最佳方式，并且我相信這不是執行此操作的 Pythonic 方式，但可以作業并且很好（經過 4 天的嘗試）。如果有人閱讀了我的測驗并可以向我解釋一個更好的方法，或者我很樂意了解和學習的 Python 方法，所以請對評論和討論我的解決方案感到滿意。
