+// without accessing its internals.
+//
+// Many test assertions are qualitative rather than quantitative.
+// They capture the design highlights of the strategy without requiring a definite value,
+// so that the test suite is not fragile to minor changes in the strategy implementation.
+//
+// Topology graphes in this test suite are shown in ASCII art,
+// in a style similar to ns-3 and ndnSIM examples.
+// They are enclosed in multi-line comments, which is an intentional violation of
+// code style rule 3.25. This is necessary because some lines ends with '\' which
+// would cause "multi-line comment" compiler warning if '//' comments are used.
