Comment (by Tye Z. <tye.zdrojewski@…>):

 Ok, so if I have a class {{{TestMe}}}...


 {{{
 class TestMe
 {
 protected:
    bool protectedValue = 0;
    int protectedMethod(int arg) { ... }
    void someProtectedBehavior() { ... }
 }
 }}}
 I will usually create a fixture as a subclass:
 {{{
 /**
  * Override methods to add test functionality
  */
 class TestMeFixture : public TestMe
 {
    // override production behavior for testing
    void someProtectedBehavior() { ... }
 }

 BOOST_FIXTURE_TEST_SUITE( MyTestSuite, TestMeFixture )
 BOOST_AUTO_TEST_CASE( test_top_level_values )
 {
    int expected = 123;
    BOOST_CHECK_EQUAL(expected, protectedMethod(456)); // call protected
 method
    BOOST_CHECK(protectedValue); // get protected value
    ...
 }
 BOOST_AUTO_TEST_SUITE_END()
 }}}
 ...which is far more concise than writing a subclass as separate from the
 fixture, which would force you to write all sorts of getters and setters
 and wrappers for protected members.
