-// This sample teaches how to reuse a test fixture in multiple test
-// cases by deriving sub-fixtures from it.
-//
-// When you define a test fixture, you specify the name of the test
-// case that will use this fixture. Therefore, a test fixture can
-// be used by only one test case.
-//
-// Sometimes, more than one test cases may want to use the same or
-// slightly different test fixtures. For example, you may want to
-// make sure that all tests for a GUI library don't leak important
-// system resources like fonts and brushes. In Google Test, you do
-// this by putting the shared logic in a super (as in "super class")
-// test fixture, and then have each test case use a fixture derived
-// from this super fixture.
