One is to name the test module by starting it with <code class="docutils literal notranslate"><span class="pre">test_</span></code> and end it with the name of the module being tested. The test methods in the test module should start with <code class="docutils literal notranslate"><span class="pre">test_</span></code> and end with a description of what the method is testing. This is needed so that the methods are recognized by the test driver as test methods. Also, no documentation string for the method should be included. A comment (such as <code class="docutils literal notranslate"><span class="pre">#</span> <span class="pre">Tests</span> <span class="pre">function</span> <span class="pre">returns</span> <span class="pre">only</span> <span class="pre">True</span> <span class="pre">or</span> <span class="pre">False</span></code>) should be used to provide documentation for test methods.

This leads to a few guidelines to be followed:</p> <ul> <li><p class="first">The testing suite should exercise all classes, functions, and constants. This includes not just the external API that is to be presented to the outside world but also “private” code.</p> </li> <li><p class="first">Whitebox testing (examining the code being tested when the tests are being written) is preferred. Blackbox testing (testing only the published user interface) is not complete enough to make sure all boundary and edge cases are tested.</p> </li> <li><p class="first">Make sure all possible values are tested including invalid ones. This makes sure that not only all valid values are acceptable but also that improper values are handled correctly.</p> </li> <li><p class="first">Exhaust as many code paths as possible. Test where branching occurs and thus tailor input to make sure as many different paths through the code are taken.</p> </li> <li><p class="first">Add an explicit test for any bugs discovered for the tested code. This will make sure that the error does not crop up again if the code is changed in the future.</p> </li> <li><p class="first">Make sure to clean up after your tests (such as close and remove all temporary files).</p> </li> <li><p class="first">If a test is dependent on a specific condition of the operating system then verify the condition already exists before attempting the test.</p> </li> <li><p class="first">Import as few modules as possible and do it as soon as possible. This minimizes external dependencies of tests and also minimizes possible anomalous behavior from side-effects of importing a module.</p> </li> <li><p class="first">Try to maximize code reuse. On occasion, tests will vary by something as small as what type of input is used. Minimize code duplication by subclassing a basic test class with a class that specifies the input:</p> <div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="k">class</span> <span class="nc">TestFuncAcceptsSequences</span><span class="p">(</span><span class="n">unittest</span><span class="o">.</span><span class="n">TestCase</span><span class="p">):</span> <span class="n">func</span> <span class="o">=</span> <span class="n">mySuperWhammyFunction</span> <span class="k">def</span> <span class="nf">test_func</span><span class="p">(</span><span class="bp">self</span><span class="p">):</span> <span class="bp">self</span><span class="o">.</span><span class="n">func</span><span class="p">(</span><span class="bp">self</span><span class="o">.</span><span class="n">arg</span><span class="p">)</span> <span class="k">class</span> <span class="nc">AcceptLists</span><span class="p">(</span><span class="n">TestFuncAcceptsSequences</span><span class="p">):</span> <span class="n">arg</span> <span class="o">=</span> <span class="p">[</span><span class="mi">1</span><span class="p">,</span> <span class="mi">2</span><span class="p">,</span> <span class="mi">3</span><span class="p">]</span> <span class="k">class</span> <span class="nc">AcceptStrings</span><span class="p">(</span><span class="n">TestFuncAcceptsSequences</span><span class="p">):</span> <span class="n">arg</span> <span class="o">=</span> <span class="s1">'abc'</span> <span class="k">class</span> <span class="nc">AcceptTuples</span><span class="p">(</span><span class="n">TestFuncAcceptsSequences</span><span class="p">):</span> <span class="n">arg</span> <span class="o">=</span> <span class="p">(</span><span class="mi">1</span><span class="p">,</span> <span class="mi">2</span><span class="p">,</span> <span class="mi">3</span><span class="p">)</span> </pre></div> </div> </li> </ul> <div class="admonition seealso"> <p class="first admonition-title">See also</p> <dl class="last docutils"> <dt>Test Driven Development</dt> <dd>A book by Kent Beck on writing tests before code.</dd> </dl> </div> </div> <div class="section" id="running-tests-using-the-command-line-interface"> <span id="regrtest"></span><h2>25.5.2.
