+All tests in the same test case must use the same test fixture
+class, so mixing TEST_F and TEST in the same test case is
+illegal.  In test case BadDynamicFixture1,
+test FixtureBase is defined using TEST_F but
+test TestBase is defined using TEST.  You probably
+want to change the TEST to TEST_F or move it to another test

+All tests in the same test case must use the same test fixture

+you defined test FixtureBase and test Derived
+using two different test fixture classes.  This can happen if
+the two classes are from different namespaces or translation
+units and have the same name.  You should probably rename one
+of the classes to put the tests into different test cases.
