+ * This class implements the test harness for search configuration tests.
+ * These tests are designed to ensure that the correct search engines are
+ * loaded for the various region/locale configurations.
+ *
+ * The configuration for each test is represented by an object having the
+ * following properties:
+ *
+ * - identifier (string)
+ *   The identifier for the search engine under test.
+ * - default (object)
+ *   An inclusion/exclusion configuration (see below) to detail when this engine
+ *   should be listed as default.
+ *
+ * The inclusion/exclusion configuration is represented as an object having the
+ * following properties:
+ *
+ * - included (array)
+ *   An optional array of region/locale pairs.
+ * - excluded (array)
+ *   An optional array of region/locale pairs.
+ *
+ * If the object is empty, the engine is assumed not to be part of any locale/region
+ * pair.
+ * If the object has `excluded` but not `included`, then the engine is assumed to
+ * be part of every locale/region pair except for where it matches the exclusions.
+ *
+ * The region/locale pairs are represented as an object having the following
+ * properties:
+ *
+ * - region (array)
+ *   An array of two-letter region codes.
+ * - locale (object)
+ *   A locale object which may consist of:
+ *   - matches (array)
+ *     An array of locale strings which should exactly match the locale.
+ *   - startsWith (array)
+ *     An array of locale strings which the locale should start with.
