<h1>Testing<a class="headerlink" href="#testing" title="Permalink to this headline">¶</a></h1>
<p>Phatch uses two strategies for testing:</p>
<ul class="simple">
<li>acceptance testing for all possible image processing pipelines</li>
<li>unit tests by doctests</li>
</ul>
<div class="section" id="acceptance-testing">
<h2>Acceptance testing<a class="headerlink" href="#acceptance-testing" title="Permalink to this headline">¶</a></h2>
<p>The acceptance testing uses the images inside the <tt class="docutils literal"><span class="pre">tests/input</span></tt> folder. To get all options for image acceptance testing, run this command from the <tt class="docutils literal"><span class="pre">tests</span></tt> folder:</p>
<div class="highlight-python"><pre>python acceptance_test.py --help</pre>
</div>
<p>Here are some examples, choose one of the two listed commands ...</p>
<ul>
<li><p class="first">To run all tests use:</p>
<div class="highlight-python"><pre>python acceptance_test.py --all
python acceptance_test.py -a</pre>
</div>
</li>
<li><p class="first">To run only the library tests use:</p>
<div class="highlight-python"><pre>python acceptance_test.py --tag=library
python acceptance_test.py -t library</pre>
</div>
</li>
<li><p class="first">To run only tests with a certain tag use:</p>
<div class="highlight-python"><pre>python acceptance_test.py --tag=tag_name
python acceptance_test.py -t tag_name</pre>
</div>
</li>
<li><p class="first">To test only one action:</p>
<div class="highlight-python"><pre>python acceptance_test.py --select=action_name
python acceptance_test.py -s action_name</pre>
</div>
</li>
</ul>
</div>
<div class="section" id="doctests">
<h2>Doctests<a class="headerlink" href="#doctests" title="Permalink to this headline">¶</a></h2>
<p>We chose for doctests as it saves time by being both unit tests and documentation. Please add doctests to the code you contribute.</p>
<p>Run the doctests inside the <tt class="docutils literal"><span class="pre">tests</span></tt> folder:</p>
<div class="highlight-python"><pre>python doc_test.py</pre>
</div>
<p>This will automatically also be run by the bzr precommit hook.</p>
