/**
 * @file
 * This file contains tests for the update module. The overarching methodology
 * of these tests is we need to compare a given state of installed modules and
 * themes (e.g. version, project grouping, timestamps, etc) vs. a current
 * state of what the release history XML files we fetch say is available.  We
 * have dummy XML files (in the 'tests' subdirectory) that describe various
 * scenarios of what's available for different test projects, and we have
 * dummy .info file data (specified via hook_system_info_alter() in the
 * update_test helper module) describing what's currently installed.  Each
 * test case defines a set of projects to install, their current state (via
 * the 'update_test_system_info' variable) and the desired availabile update
 * data (via the 'update_test_xml_map' variable), and then performs a series
 * of assertions that the report matches our expectations given the specific
 * initial state and availability scenario.
