The neutron.tests.tools was recently made public and along with it the WarningsFixture. However the WarningsFixture as-is doesn't support filtering warnings from other modules. This patch address that by accepting an constructor arg to add other module regular expressions to filter. It also moves WarningsFixture to the fixture module where it seems to make the most sense. For a sample consumption patch see: https://review.openstack.org/#/c/651370/ Change-Id: I08c713916aef407ba108ed2c67c3e99892f5883a
