Save and restore siteconfig settings for all unit tests.
Review Request #10478 — Created March 31, 2019 and submitted
We had a number of siteconfig settings leaks between tests, caused by
one test modifying the settings and another utilizing those settings.
This could subtly impact some tests in ways that weren't always clear,
and it could depend on the order in which tests were run or the order in
which events happened. This largely happens because we don't necessarily
fully replace the
SiteConfigurationin-between tests, instead often
using a cached copy.
This change updates all individual tests that need to modify siteconfig
to use the
siteconfig_settingscontext manager, which will handle
setting and restoring the settings.
Classes that modify these settings in
setUpnow ensure they've cleaned
up after themselves in
tearDown, preventing further leaks. Some do
this by saving and restoring an individual setting that's modified, and
others save a copy of all settings and restore them, depending on the
needs of the test suite.
Room for improvement going forward would be to add formal support in our
TestCaseto let classes define global siteconfig settings and handle
the setting and restoring automatically, to completely remove the need
for custom management of siteconfig, but that's outside the scope of
All unit tests pass.
Fixed alignment issues.
