"""Test PluginsBlockedForUrls policy effect on CrOS behavior.
This test verifies the behavior of Chrome OS with a set of valid values
for the PluginsBlockedForUrls user policy, when DefaultPluginsSetting=1
(i.e., allow running of plugins by default, except on sites listed in
PluginsBlockedForUrls). These valid values are covered by 3 test cases:
SiteBlocked_Block, SiteNotBlocked_Run, and NotSet_Run.
This test is also configured with DisablePluginFinder=True and
When the policy value is None (as in case NotSet_Run), then running of
plugins is allowed on every site. When the value is set to one or more
URLs (as in SiteBlocked_Block and SiteNotBlocked_Run), plugins are run
on every site except for those sites whose domain matches any of the
listed URLs.
A related test, policy_PluginsBlockedForUrls, has DefaultPluginsSetting=2
(i.e., block running of plugins by default, except on sites in domains
listed in PluginsAllowedForUrls).
