mocking

问题 I have a proprietary repository format and I'm trying to develop a Python module to process these repositories. Repo format goes as: /home/X/ | + alpha/ | + beta/ | + project.conf Here, X is a project. alpha and beta are folders inside this project and they represent groups in this project. A group is a container in this repo and what it represents is really not relevant for this question. The repo X also has files in its root level; project.conf is an example of such a file. I have a class

问题 We are using jest for mocking. I have a function which will greet us based on the time that file looks like below: export default function getGreetingMessage() { const today = new Date(); const curHr = today.getHours(); if (curHr < 12) { return 'Good morning'; } else if (curHr < 18) { return 'Good afternoon'; } return 'Good evening'; } And My test file will look like below import getGreetingMessage from '../messages'; describe('messages', () => { function setup(date) { const DATE_TO_USE = new

问题 Library module: # mod.py def foo(): bar1("arg1") bar2("arg2x", "arg2y") def bar1(x): pass def bar2(x, y): pass Test module: # test_mod.py from mod import foo def test_foo(mocker): mock = mocker.MagicMock() mock.attach_mock(mocker.patch("mod.bar1"), "b1") mock.attach_mock(mocker.patch("mod.bar2", autospec=True), "b2") foo() mock.assert_has_calls( [ mocker.call.b1("arg1"), mocker.call.b2("arg2x", "arg2y"), ] ) The mocker fixture is from pytest-mock plugin. Execute the MCVE with python -m pytest

问题 I know that it is possible to mock a single enum(using How to mock an enum singleton class using Mockito/Powermock?), but I have like 1000 of enum values and they can call 5 different constructors. The enum values are often changing in development. I want to really mock only one or two for my JUnit test. I don't care about the rest, but they are still instantiated, which calls some nasty stuff, which loads the values for the enum from the file system. Yes I know It's very bad design. But for

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 When a unittest.mock.Mock object has been called, I can check for the argument values with the exact signature of the call: from unittest.mock import Mock m = Mock() # creation of mock m('foo', bar='baz') # call to the mock m.assert_called_once_with('foo', bar='baz') # check call arguments Checking for a different signature with the same values will fail. E.g., if we check with 'baz' as a positional argument instead of a named argument, the assertion will fail: m.assert_called_once_with('foo'
