+// In this example, we use a more advanced feature of Google Test called
+// test fixture.
+//
+// A test fixture is a place to hold objects and functions shared by
+// all tests in a test case.  Using a test fixture avoids duplicating
+// the test code necessary to initialize and cleanup those common
+// objects for each test.  It is also useful for defining sub-routines
+// that your tests need to invoke a lot.
+//
+// <TechnicalDetails>
+//
+// The tests share the test fixture in the sense of code sharing, not
+// data sharing.  Each test is given its own fresh copy of the
+// fixture.  You cannot expect the data modified by one test to be
+// passed on to another test, which is a bad idea.
+//
+// The reason for this design is that tests should be independent and
+// repeatable.  In particular, a test should not fail as the result of
+// another test's failure.  If one test depends on info produced by
+// another test, then the two tests should really be one big test.
+//
+// The macros for indicating the success/failure of a test
+// (EXPECT_TRUE, FAIL, etc) need to know what the current test is
+// (when Google Test prints the test result, it tells you which test
+// each failure belongs to).  Technically, these macros invoke a
+// member function of the Test class.  Therefore, you cannot use them
+// in a global function.  That's why you should put test sub-routines
+// in a test fixture.
