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.

In this example only test_case1 and test_case2 have fixture F assigned. In the next section you going to see
what can be done if all test cases in a test suite require the same fixture.
