+/**
+ * Defines some shared functions used by all update tests.
+ *
+ * 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) against a current state of what the release history XML
+ * files we fetch say is available. We have dummy XML files (in the
+ * core/modules/update/tests directory) 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 available 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.
