问题 I'm using python mocks to assert that a particular object was created with the right arguments. This is how my code looks: class Installer: def __init__(foo, bar, version): # Init stuff pass def __enter__(self): return self def __exit__(self, type, value, tb): # cleanup pass def install(self): # Install stuff pass class Deployer: def deploy(self): with Installer('foo', 'bar', 1) as installer: installer.install() Now, I want to assert that installer was created with the right arguments. This

问题 How to just list all discovered tests? I found this command: python3.4 -m unittest discover -s . But it's not exactly what I want, because the above command executes tests. I mean let's have a project with a lot of tests. Execution time is a few minutes. This force me to wait until tests are finished. What I want is something like this (above command's output) test_choice (test.TestSequenceFunctions) ... ok test_sample (test.TestSequenceFunctions) ... ok test_shuffle (test

问题 I'm trying to test that my authentication fails. The exception is raised but not caught by assertRaises . What am I missing here? def test_auth(self): from graphql_jwt.exceptions import PermissionDenied with self.assertRaises(PermissionDenied): response = self.client.execute(self.query) Traceback: Creating test database for alias 'default'...

问题 I would like to capture messages sent to stdout (our stderr ) temporarily during a test and assert if some string patterns occurred in these messages: import unittest class SomeTest(unittest.TestCase): def test_stdout(self): output = "" function_that_writes_to_stdout() # How to capture stdout in output temporarily? self.assertIn("some message", output) I found a similar question, but the accepted answer suggests to capture messages sent to stdout for all test cases. Yes, I know that it's not

问题 I have a decorator that looks like so: def validate_something(func): def validate_s(request): if request.property: render_to_response('template.jinja', 'error' return func(request) return validate_something I'm trying to test it like so. I load the local WSGI stack as an app. from webtest import TestApp def setUp(self): self.app = TestApp(target_app()) self.config = testing.setUp(request=testing.DummyRequest) def test_something(self): def test_func(request): return 1 request = testing

问题 How to create a temporary files/directories with user defined names in python. I am aware of tempfile . However I couldn't see any function with filename as argument. Note: I need this for unit testing the glob(file name pattern matching) functionality on a temporary directory containing temporary files rather than using the actual file system. 回答1: You can use open() with whatever file name you need. e.g. open(name, 'w') Open Or import os import tempfile print 'Building a file name yourself:
