The <span class="emphasis"><em>UTF</em></span> defines the generic fixture model as follows:
|
|
</p>
|
|
<pre class="programlisting"><span class="keyword">struct</span> <span class="special"><</span><span class="identifier">fixture</span><span class="special">-</span><span class="identifier">name</span><span class="special">>{</span>
|
|
<span class="special"><</span><span class="identifier">fixture</span><span class="special">-</span><span class="identifier">name</span><span class="special">>();</span> <span class="comment">// setup function</span>
|
|
<span class="special">~<</span><span class="identifier">fixture</span><span class="special">-</span><span class="identifier">name</span><span class="special">>();</span> <span class="comment">// teardown function</span>
|
|
<span class="special">};</span>
|
|
</pre>
|
|
<p>
|
|
In other words a fixture is expected to be implemented as a class where the
|
|
class constructor serves as a setup method and class destructor serves as
|
|
teardown method. The <span class="emphasis"><em>UTF</em></span> opted to avoid explicit names
|
|
in fixture interface for setup and teardown methods, since is considered
|
|
most natural in C++ for tasks similar to RAII and coincides with the pure
|
|
C++ solution discusses earlier.

|
|
The above interface prevents you to report errors in the teardown procedure
|
|
using an exception. It does make sense though: if somehow more than one
|
|
fixture is assigned to a test unit, you want all teardown procedures to
|
|
run, even if some may experience problems.
