Python flask请求处理程序中使用的模拟函数
我试图模拟在测试文件的flask请求处理程序中调用的Python flask请求处理程序中使用的模拟函数,python,unit-testing,flask,mocking,python-unittest,Python,Unit Testing,Flask,Mocking,Python Unittest,我试图模拟在测试文件的flask请求处理程序中调用的upload\u image函数 但是,在我当前的实现中,原始函数仍然在请求处理程序中调用,并且不会返回模拟的返回值。如何从test.py文件中模拟此函数 守则: tests/test.py import os from unittest.mock import patch def test_image_upload(test_client): with patch("app.utils.upload_image", 'test_pa
upload\u image

文件中模拟此函数
守则:
tests/test.py
import os
from unittest.mock import patch
def test_image_upload(test_client):
with patch("app.utils.upload_image", 'test_path'):
test_file_path = os.path.dirname(os.path.abspath(__file__)) + '/test_file.png'
f = open(test_file_path, 'rb')
data = {
'num-files': 1,
'test_file.png': f
}
response = test_client.post('/file/upload', data=data)
assert response.status_code == 200
from utils import upload_image
@app.route('/file/upload', methods=['POST'])
def upload_file():
# should be returning 'test_path', but is actually uploading the file and returning a URL
file_url = upload_image(image)
return jsonify({'file_url': file_url})
app/files/handler.py
import os
from unittest.mock import patch
def test_image_upload(test_client):
with patch("app.utils.upload_image", 'test_path'):
test_file_path = os.path.dirname(os.path.abspath(__file__)) + '/test_file.png'
f = open(test_file_path, 'rb')
data = {
'num-files': 1,
'test_file.png': f
}
response = test_client.post('/file/upload', data=data)
assert response.status_code == 200
from utils import upload_image
@app.route('/file/upload', methods=['POST'])
def upload_file():
# should be returning 'test_path', but is actually uploading the file and returning a URL
file_url = upload_image(image)
return jsonify({'file_url': file_url})
我认为您应该修补
app.files.handler.upload\u image
,因为您正在将函数导入当前名称空间。如果你导入了utils,你会给app.utils.upload\u image添加补丁;utils.upload_image()是的,就是这样。谢谢
