<overview>
<p>
A JUnit 3.8 test method that overrides a non-empty <code>tearDown</code> method should call <code>super.tearDown</code> to make sure that
the superclass performs its de-initialization routines. Not calling <code>tearDown</code> may result in test failures in subsequent tests, or
allow the current state to persist and affect any following tests.
</p>

</overview>
<recommendation>
<p>
Call <code>super.tearDown</code> at the end of the overriding <code>tearDown</code> method.
</p>

</recommendation>
<example>

<p>In the following example, <code>TearDownNoSuper.tearDown</code> does not call <code>super.tearDown</code>,
which may cause subsequent tests to fail, or allow the internal state to be maintained. However, <code>TearDownSuper.tearDown</code>
<em>does</em> call <code>super.tearDown</code>, at the end of the method, to enable 
<code>FrameworkTestCase.tearDown</code> to perform de-initialization.</p>
