Why: * SearchFilters.php allows the caller to search by a regex that is applied to the pattern. * This script can be expanded to allow callers to specify what consequence should be associated with the filters that are outputted. What: * Add a 'consequence' option to the SearchFilters.php maintenance script, which is applied through a LIKE query on the af_actions column. ** This can be specified with or without the pattern option. ** Instead of making pattern required, the script now requires that one of consequence or pattern is provided. * Expand the tests for the script for this new code, along with using the new ::expectCallToFatalError method to be able to test previously untestable code. Bug: T373148 Change-Id: I1b507d8f9dc1f4cf91ee4f83ccde745eb6d46d6d
