| To automate the task of assigning a fixture for the test case, for test case creation use the macro |
| BOOST_FIXTURE_TEST_CASE in place of the macro <code class="computeroutput"><a class="link" href="../test-organization/auto-nullary-test-case.html#BOOST_AUTO_TEST_CASE">BOOST_AUTO_TEST_CASE</a></code>: |

| <p class="first-line-indented"> |
| The only difference from the macro <code class="computeroutput"><a class="link" href="../test-organization/auto-nullary-test-case.html#BOOST_AUTO_TEST_CASE">BOOST_AUTO_TEST_CASE</a></code> is the presence of an extra argument |
| - fixture name. Unlike the pure C++ solution you have direct access to the public and protected members of the |
| fixture, though you still need to refer to the fixture name in every test case. |
