<section id="writing-an-effective-bug-report">
<h2>Writing an effective bug report<a class="headerlink" href="#writing-an-effective-bug-report" title="Permalink to this heading">#</a></h2>
<p>When reporting a bug, start with the question
<code class="docutils literal notranslate"><span class="pre">What</span> <span class="pre">does</span> <span class="pre">a</span> <span class="pre">bug</span> <span class="pre">report</span> <span class="pre">need</span> <span class="pre">to</span> <span class="pre">tell</span> <span class="pre">the</span> <span class="pre">developer</span></code>.</p>
<p>Generally you want the following parts covered:</p>
<ul class="simple">
<li><p>What is the problem</p></li>
<li><p>How can the developer reproduce the problem (to see it for themselves), to
bisect when it was introduced or to find if it got fixed already.</p></li>
<li><p>At what point does the problem occur</p></li>
<li><p>What environment did this occur in</p></li>
</ul>
<p>Make sure the above items are covered and the bug is easy to review and parse:</p>
<ul class="simple">
<li><p><strong>Title</strong> should clearly describe the problem. Bugs are often sorted from
the issue list which only contains the title</p></li>
<li><p><strong>Logs</strong> should generally be attachments (drag & drop or click on bottom bar
when entering issue text) and not inline with the issue.</p></li>
<li><p><strong>Reproduction steps</strong> and <strong>environment</strong> should be clearly highlighted. If
running commands reproduce the issue (very common), the commands should be
in a code block/script format.</p></li>
</ul>
<section id="describing-the-problem">
<h3>Describing the problem<a class="headerlink" href="#describing-the-problem" title="Permalink to this heading">#</a></h3>
<p>Make sure the issue is obvious or provide a link explaining why the expected
result is not met.</p>
<p>Examples:</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">(Core</span> <span class="pre">dump)</span> <span class="pre">seen</span></code> is obvious since there should be no core dumps</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">Failure</span> <span class="pre">trying</span> <span class="pre">to</span> <span class="pre">read</span> <span class="pre">attribute</span> <span class="pre">X</span> <span class="pre">in</span> <span class="pre">cluster</span> <span class="pre">Y</span> <span class="pre">which</span> <span class="pre">is</span> <span class="pre">marked</span> <span class="pre">MANDATORY</span> <span class="pre">in</span> <span class="pre">the</span> <span class="pre">spec</span></code>
references the spec and describes why attribute read should succeed.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">Failure</span> <span class="pre">trying</span> <span class="pre">to</span> <span class="pre">write</span> <span class="pre">attribute</span> <span class="pre">X</span> <span class="pre">in</span> <span class="pre">cluster</span> <span class="pre">Y,</span> <span class="pre">which</span> <span class="pre">is</span> <span class="pre">enabled</span> <span class="pre">since</span> <span class="pre">cluster</span> <span class="pre">FeatureMap</span> <span class="pre">enabled</span> <span class="pre">X</span> <span class="pre">and</span> <span class="pre">spec</span> <span class="pre">describes</span> <span class="pre">as</span> <span class="pre">writable.</span></code>
references the spec and explicitly states that an optional attribute is
enabled based on device status</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">Running</span> <span class="pre">certification</span> <span class="pre">test</span> <span class="pre">TC-A-B-C</span> <span class="pre">(link</span> <span class="pre">included)</span> <span class="pre">fails</span> <span class="pre">at</span> <span class="pre">step</span> <span class="pre">3:</span> <span class="pre">test</span> <span class="pre">case</span> <span class="pre">asks</span> <span class="pre">for</span> <span class="pre">command</span> <span class="pre">to</span> <span class="pre">succeed,</span> <span class="pre">I</span> <span class="pre">get</span> <span class="pre">ACCESS_DENIED</span> <span class="pre">instead</span></code>
describes a pre-defined test case that is expected to pass but fails. Note
that full link to the test description is needed (and should be covered by
‘how to reproduce’ part)</p></li>
</ul>
<p>Unless manually curated (e.g. few lines showing the problem), logs should be
always attachments and not inlined in the bug as the make the bug report too
long.</p>
</section>
<section id="reproduction-steps-and-when-does-the-issue-occur">
<h3>Reproduction steps and when does the issue occur<a class="headerlink" href="#reproduction-steps-and-when-does-the-issue-occur" title="Permalink to this heading">#</a></h3>
<p>Include all steps needed to reproduce the problem. Link any supporting
documentation.</p>
<p>If stating something of the form <code class="docutils literal notranslate"><span class="pre">TC-A-B-C</span> <span class="pre">step</span> <span class="pre">4</span> <span class="pre">fails</span></code> then there should be a
link to TC-A-B-C and ideally a list of the commands of each step since test
cases may change over time.</p>
<p>The bug report should contain all the information for a developer to reproduce
the issue without needing to have access to CHIP Test case repository (not
everyone does)</p>
</section>
<section id="environment-for-reproduction">
<h3>Environment for reproduction<a class="headerlink" href="#environment-for-reproduction" title="Permalink to this heading">#</a></h3>
<p>Assume that the developer will want to reproduce the issue and will try to
mirror your environment to a reasonable degree. For this, at a minimum the
platforms on which everything is running is needed.</p>
<p>Try to provide as much information as seems relevant. At a minimum this could
look like
<code class="docutils literal notranslate"><span class="pre">Failed</span> <span class="pre">to</span> <span class="pre">commission</span> <span class="pre">nrf</span> <span class="pre">board</span> <span class="pre">using</span> <span class="pre">chip-tool</span> <span class="pre">running</span> <span class="pre">on</span> <span class="pre">linux.</span> <span class="pre">Used</span> <span class="pre">build</span> <span class="pre">on</span> <span class="pre">SHA</span> <span class="pre">abcde...</span></code>.
This provides basic information (use nrf board, use chip-tool on linux, default
build) to get started. Beyond that, you can refine if more items seem relevant:</p>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">Tested</span> <span class="pre">on</span> <span class="pre">TE9</span></code> or <code class="docutils literal notranslate"><span class="pre">Tested</span> <span class="pre">on</span> <span class="pre">interop</span> <span class="pre">branch</span> <span class="pre">xyz</span></code> gives a build reference
point. Useful when branches/tags are used instead of master branch as
development happens on master branch.</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">Thread</span> <span class="pre">devices</span> <span class="pre">fail,</span> <span class="pre">tested</span> <span class="pre">with</span> <span class="pre">qpg</span> <span class="pre">and</span> <span class="pre">efr32</span></code> shows that this seems to be
a general thread issue and developer can investigate on multiple of them</p></li>
</ul>
<ul class="simple">
<li><p><code class="docutils literal notranslate"><span class="pre">Tested</span> <span class="pre">with</span> <span class="pre">avahi-build</span> <span class="pre">and</span> <span class="pre">it</span> <span class="pre">passes/fails</span></code> helps the developer with
information of non-default builds that pass/fail to narrow down the problem</p></li>
<li><p><code class="docutils literal notranslate"><span class="pre">Passes</span> <span class="pre">with</span> <span class="pre">darwin-framework-tool</span> <span class="pre">and</span> <span class="pre">repl</span> <span class="pre">but</span> <span class="pre">fails</span> <span class="pre">with</span> <span class="pre">chip-tool</span></code> helps
the developer in narrowing down the problem</p></li>
</ul>

<section id="additional-information">
