From d3f4673c1a1c3f5213840e756c5f35f7c70d46f6 Mon Sep 17 00:00:00 2001 From: Sebastiaan Zeeff <33516116+SebastiaanZ@users.noreply.github.com> Date: Sun, 23 Feb 2020 12:39:25 +0100 Subject: Use mixin-composition not inheritance for LoggingTestCase We used inheritence to add additional logging assertion methods to unittest's TestCase class. However, with the introduction of the new IsolatedAsyncioTestCase this extension strategy means we'd have to create multiple child classes to be able to use the extended functionality in all of the TestCase variants. Since that leads to undesirable code reuse and an inheritance relationship is not at all needed, I've switched to a mixin-composition based approach that allows the user to extend the functionality of any TestCase variant with a mixin where needed. --- tests/base.py | 10 +++++++--- tests/bot/cogs/test_duck_pond.py | 2 +- tests/test_base.py | 18 ++++++------------ 3 files changed, 14 insertions(+), 16 deletions(-) (limited to 'tests') diff --git a/tests/base.py b/tests/base.py index 029a249ed..21a57716a 100644 --- a/tests/base.py +++ b/tests/base.py @@ -1,5 +1,4 @@ import logging -import unittest from contextlib import contextmanager @@ -16,8 +15,13 @@ class _CaptureLogHandler(logging.Handler): self.records.append(record) -class LoggingTestCase(unittest.TestCase): - """TestCase subclass that adds more logging assertion tools.""" +class LoggingTestsMixin: + """ + A mixin that defines additional test methods for logging behavior. + + This mixin relies on the availability of the `fail` attribute defined by the + test classes included in Python's unittest method to signal test failure. + """ @contextmanager def assertNotLogs(self, logger=None, level=None, msg=None): diff --git a/tests/bot/cogs/test_duck_pond.py b/tests/bot/cogs/test_duck_pond.py index d07b2bce1..320cbd5c5 100644 --- a/tests/bot/cogs/test_duck_pond.py +++ b/tests/bot/cogs/test_duck_pond.py @@ -14,7 +14,7 @@ from tests import helpers MODULE_PATH = "bot.cogs.duck_pond" -class DuckPondTests(base.LoggingTestCase): +class DuckPondTests(base.LoggingTestsMixin, unittest.TestCase): """Tests for DuckPond functionality.""" @classmethod diff --git a/tests/test_base.py b/tests/test_base.py index a16e2af8f..23abb1dfd 100644 --- a/tests/test_base.py +++ b/tests/test_base.py @@ -3,7 +3,11 @@ import unittest import unittest.mock -from tests.base import LoggingTestCase, _CaptureLogHandler +from tests.base import LoggingTestsMixin, _CaptureLogHandler + + +class LoggingTestCase(LoggingTestsMixin): + pass class LoggingTestCaseTests(unittest.TestCase): @@ -18,19 +22,9 @@ class LoggingTestCaseTests(unittest.TestCase): try: with LoggingTestCase.assertNotLogs(self, level=logging.DEBUG): pass - except AssertionError: + except AssertionError: # pragma: no cover self.fail("`self.assertNotLogs` raised an AssertionError when it should not!") - @unittest.mock.patch("tests.base.LoggingTestCase.assertNotLogs") - def test_the_test_function_assert_not_logs_does_not_raise_with_no_logs(self, assertNotLogs): - """Test if test_assert_not_logs_does_not_raise_with_no_logs captures exception correctly.""" - assertNotLogs.return_value = iter([None]) - assertNotLogs.side_effect = AssertionError - - message = "`self.assertNotLogs` raised an AssertionError when it should not!" - with self.assertRaises(AssertionError, msg=message): - self.test_assert_not_logs_does_not_raise_with_no_logs() - def test_assert_not_logs_raises_correct_assertion_error_when_logs_are_emitted(self): """Test if LoggingTestCase.assertNotLogs raises AssertionError when logs were emitted.""" msg_regex = ( -- cgit v1.2.3 From 135d6daa4804574935cd788c5baec656765f484b Mon Sep 17 00:00:00 2001 From: Sebastiaan Zeeff <33516116+SebastiaanZ@users.noreply.github.com> Date: Sun, 23 Feb 2020 13:05:10 +0100 Subject: Use IsolatedAsyncioTestCase instead of async_test Since we upgraded to Python 3.8, we can now use the new IsolatedAsyncioTestCase test class to use coroutine-based test methods instead of our own, custom async_test decorator.

As we were using our custom, but limited, AsyncMock, I have replaced our mock with unittest's AsyncMock. Since Python 3.8 also introduces a different way of automatically detecting which attributes should be mocked with an AsyncMock, I've changed our CustomMockMixin to use this new method as well. Together with a couple other small changes, this means that our Custom Mocks now use a lazy method of detecting coroutine attributes, which significantly speeds up the test suite. --- tests/bot/cogs/test_duck_pond.py | 22 ++-- tests/bot/cogs/test_information.py | 34 +++---- tests/bot/cogs/test_token_remover.py | 4 +- tests/bot/utils/test_time.py | 3 +- tests/helpers.py | 190 ++++++++++++----------------------- tests/test_helpers.py | 63 ++---------- 6 files changed, 103 insertions(+), 213 deletions(-) (limited to 'tests') diff --git a/tests/bot/cogs/test_duck_pond.py b/tests/bot/cogs/test_duck_pond.py index 6406f0737..e164f7544 100644 --- a/tests/bot/cogs/test_duck_pond.py +++ b/tests/bot/cogs/test_duck_pond.py @@ -2,7 +2,7 @@ import asyncio import logging import typing import unittest -from unittest.mock import MagicMock, patch +from unittest.mock import AsyncMock, MagicMock, patch import discord @@ -293,8 +293,8 @@ class DuckPondTests(base.LoggingTestsMixin, unittest.IsolatedAsyncioTestCase): ) for message, expect_webhook_call, expect_attachment_call in test_values: -

By default, when an AsyncMock object is called **and awaited**, it returns a child mock of the same time (another AsyncMock) according to the "the child is a like the parent" principle. This means that the _get_diff method will return an AsyncMock unless a different return_value is explicitly provided. Because of that "child is like parent" behavior, this will happen in lines 194-196 of bot.cogs.sync.syncers (annotations added by me): ``` // `diff` will be a child AsyncMock as "child is like parent" diff = await self._get_diff(guild) // `diff._asdict` will be an AsyncMock as "child is like parent" and, // after being called, it will return an unawaited coroutine object // we assign the name `diff_dict`: diff_dict = diff._asdict() // `diff_dict` is still an unawaited coroutine object meaning that it // doesn't have an `items()` method: totals = {k: len(v) for k, v in diff_dict.items() if v is not None} ``` Original, unannotated: https://github.com/python-discord/bot/blob/c81a4d401ea434e98b0a1ece51d3d10f1a3ad226/bot/cogs/sync/syncers.py#L194-L196 This will lead to the following exception when running the tests: ```py ====================================================================== ERROR: test_sync_confirmation_context_redirect (tests.bot.cogs.sync.test_base.SyncerSyncTests) (ctx=None, author=, message=None) If ctx is given, a new message should be sent and author should be ctx's author. ---------------------------------------------------------------------- Traceback (most recent call last): File "/home/sebastiaan/pydis/repositories/bot/tests/bot/cogs/sync/test_base.py", line 348, in test_sync_confirmation_context_redirect await self.syncer.sync(guild, ctx) File "/home/sebastiaan/pydis/repositories/bot/bot/cogs/sync/syncers.py", line 196, in sync totals = {k: len(v) for k, v in diff_dict.items() if v is not None} AttributeError: 'coroutine' object has no attribute 'items' ``` The solution is to assign an explicit return value so the parent mock doesn't "guess" and return an object of its own type. I previously did that by providing a specific `_Diff` object as the return value, but I should have gone with a `MagicMock` to signify that it's not an important return value; it's just something that needs to support/mimic the API we use on it.

In particular, I had to make a few changes: - Mocking the async post() context manager correctly Since `ClientSession.post` returns an async context manager when called, we need to make sure to assign the return value to the __aenter__ method of whatever `post()` returns, not of `post` itself (i.e.. when it's not called). - Use the new AsyncMock assert methods `assert_awaited_once` and `assert_awaited_once_with` Objects of the new `unittest.mock.AsyncMock` class have special methods to assert what they were called with that also assert that specific coroutine object was awaited. This means we test two things in one: Whether or not it was called with the right arguments and whether or not the returned coroutine object was then awaited. - Patch `functools.partial` as `partial` objects are compared by identity When you create two partial functions of the same function, you'll end up with two different `partial` objects. Since `partial` objects are compared by identity, you can't compare a `partial` created in a test method to that created in the callable you're trying to test. They will always compare as `False`. Since we're not interested in actually creating `partial` objects, I've just patched `functools.partial` in the namespace of the module we're testing to make sure we can compare them. --- tests/bot/cogs/test_snekbox.py | 68 +++++++++++++++++------------------------- 1 file changed, 27 insertions(+), 41 deletions(-) (limited to 'tests') diff --git a/tests/bot/cogs/test_snekbox.py b/tests/bot/cogs/test_snekbox.py index 985bc66a1..9cd7f0154 100644 --- a/tests/bot/cogs/test_snekbox.py +++ b/tests/bot/cogs/test_snekbox.py @@ -1,74 +1,68 @@ import asyncio import logging import unittest -from functools import partial -from unittest.mock import MagicMock, Mock, call, patch +from unittest.mock import AsyncMock, MagicMock, Mock, call, patch from bot.cogs import snekbox from bot.cogs.snekbox import Snekbox from bot.constants import URLs -from tests.helpers import ( -
