"""Pylons application test package

This package assumes the Pylons environment is already loaded, such as
when this script is imported from the `nosetests --with-pylons=test.ini`
command.

This module initializes the application via ``websetup`` (`paster
setup-app`) and provides the base testing objects.

nosetests -x - fail on first error
nosetests rhodecode.tests.functional.test_admin_settings:TestSettingsController.test_my_account
nosetests --pdb --pdb-failures
nosetests --with-coverage --cover-package=rhodecode.model.validators rhodecode.tests.test_validators

optional FLAGS:
    RC_WHOOSH_TEST_DISABLE=1 - skip whoosh index building and tests
    RC_NO_TMP_PATH=1 - disable new temp path for tests, used mostly for test_vcs_operations
