| If all test cases in a test require the same fixture (you can group test cases in the test suite based on a |
| fixture required) you can make another step toward an automation of a test fixture assignment. To assign the |
| same shared fixture for all test cases in a test suite use the macro BOOST_FIXTURE_TEST_SUITE in place of the |
| macro <code class="computeroutput"><a class="link" href="../test-organization/auto-test-suite.html#BOOST_AUTO_TEST_SUITE">BOOST_AUTO_TEST_SUITE</a></code> for automated test suite creation and registration. |

| Once again the only difference from the macro <code class="computeroutput"><a class="link" href="../test-organization/auto-test-suite.html#BOOST_AUTO_TEST_SUITE">BOOST_AUTO_TEST_SUITE</a></code> usage is the presence of |
| an extra argument - the fixture name. And now, you not only have direct access to the public and protected members |
| of the fixture, but also do not need to refer to the fixture name in test case definition. All test cases assigned |
| the same fixture automatically. |
