Here is an example:<p><pre><div class="fragment"> <span class="keyword">class </span>MathTest : <span class="keyword">public</span> CppUnit::<a class="code" href="class_test_fixture.html">TestFixture</a> { <span class="keyword">protected</span>: <span class="keywordtype">int</span> m_value1, m_value2; <span class="keyword">public</span>: MathTest() {} <span class="keywordtype">void</span> <a class="code" href="class_test_fixture.html#a1">setUp</a> () { m_value1 = 2; m_value2 = 3; } }</div></pre><p>For each test implement a method which interacts with the fixture. Verify the expected results with assertions specified by calling CPPUNIT_ASSERT on the expression you want to test:<p><pre><div class="fragment"> <span class="keyword">public</span>: <span class="keywordtype">void</span> testAdd () { <span class="keywordtype">int</span> result = m_value1 + m_value2; <a class="code" href="group___assertions.html#ga0">CPPUNIT_ASSERT</a>( result == 5 ); }</div></pre><p>Once the methods are defined you can run them. To do this, use a <a class="el" href="class_test_caller.html">TestCaller</a>.<p><pre><div class="fragment"> CppUnit::Test *test = <span class="keyword">new</span> CppUnit::TestCaller<MathTest>( <span class="stringliteral">"testAdd"</span>, &MathTest::testAdd ); test->run();</div></pre><p>The tests to be run can be collected into a <a class="el" href="class_test_suite.html">TestSuite</a>.<p><pre><div class="fragment"> <span class="keyword">public</span>: <span class="keyword">static</span> CppUnit::TestSuite *MathTest::suite () { CppUnit::TestSuite *suiteOfTests = <span class="keyword">new</span> CppUnit::TestSuite; suiteOfTests->addTest(<span class="keyword">new</span> CppUnit::TestCaller<MathTest>( <span class="stringliteral">"testAdd"</span>, &MathTest::testAdd)); suiteOfTests->addTest(<span class="keyword">new</span> CppUnit::TestCaller<MathTest>( <span class="stringliteral">"testDivideByZero"</span>, &MathTest::testDivideByZero)); <span class="keywordflow">return</span> suiteOfTests; }</div></pre><p>A set of macros have been created for convenience.
