<div class="markdown_content"><p>Hallo zusammen,</p> <p>ich habe versucht einen UnitTest über folgendes Python-Skript in CODESYS auszuführen. Der Test enthält Subtests und das Skript funktioniert in PyCharm einwandfrei, allerdings nicht in CODESYS. Hier das Skript.</p> <div class="codehilite"><pre><span></span><span class="kn">import</span> <span class="nn">unittest</span> <span class="k">class</span> <span class="nc">MyTest</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="k">def</span> <span class="nf">testCase1</span><span class="p">(</span><span class="bp">self</span><span class="p">):</span> <span class="k">for</span> <span class="n">i</span> <span class="ow">in</span> <span class="nb">range</span><span class="p">(</span><span class="mi">6</span><span class="p">):</span> <span class="k">with</span> <span class="bp">self</span><span class="o">.</span><span class="n">subTest</span><span class="p">(</span><span class="n">i</span><span class="o">=</span><span class="n">i</span><span class="p">):</span> <span class="bp">self</span><span class="o">.</span><span class="n">assertEqual</span><span class="p">(</span><span class="n">i</span> <span class="o">%</span> <span class="mi">2</span><span class="p">,</span> <span class="mi">0</span><span class="p">,</span> <span class="s2">"Fehler, Rest ungleich 0"</span><span class="p">)</span> <span class="k">if</span> <span class="vm">__name__</span> <span class="o">==</span> <span class="s1">'__main__'</span><span class="p">:</span> <span class="n">unittest</span><span class="o">.</span><span class="n">main</span><span class="p">()</span> </pre></div> <p>Ich bekomme folgende Fehlermeldung:</p> <div class="codehilite"><pre><span></span><span class="n">AttributeError</span><span class="p">:</span> <span class="s1">'MyTest'</span> <span class="k">object</span> <span class="n">has</span> <span class="k">no</span> <span class="n">attribute</span> <span class="s1">'subTest'</span> </pre></div> <p>Wird die Funktion einfach (noch) nicht unterstützt, weil eine ältere Python-Version verwendet wird?<br/> Gibt es einen Workaround?</p> <p>Vielen Dank schonmal.</p></div>
