问题 Trying to write a testcase for my class based function. This is skeleton of my class class Library(object): def get_file(self): pass def query_fun(self): pass def get_response(self): self.get_file() response = self.query_fun() # some business logic here return response I need to create a testcase that can mock just the query_fun and do the rest. tried below but seems is not the right direction: from unittest import mock, TestCase from library.library import Library class TestLibrary(TestCase)

问题 TL;DR How can I patch or mock "any functions that are not being called/used directly" ? Sceneario I have a simple unit-test snippet as # utils/functions.py def get_user_agents(): # sends requests to a private network and pulls data return pulled_data # my_module/tasks.py def create_foo(): from utils.functions import get_user_agents value = get_user_agents() # do something with value return some_value # test.py class TestFooKlass(unittest.TestCase): def setUp(self): create_foo() def test_foo

问题 I have a model and I'm trying to test validation without invoking the database layer. Rather than describe with words I'll just post up some example code. The issue here is the ForeignKey relationship to Bar, which isn't relevant to what I'm trying to test but is stopping me from running the test that I want. First, myapp/models.py : from django.core.exceptions import ValidationError from django.db import models class BadFooError(ValidationError): pass class Bar(models.Model): description =

问题 I have been exploring mock and pytest for a few days now. I have the following method: def func(): if not os.path.isdir('/tmp/folder'): os.makedirs('/tmp/folder') In order to unit test it, I have decided to patch os.path.isdir and os.makedirs, as shown: @patch('os.path.isdir') @patch('os.makedirs') def test_func(patch_makedirs, patch_isdir): patch_isdir.return_value = False assert patch_makedirs.called == True The assertion fails, irrespective of the return value from patch_isdir. Can someone
