<div class="sreweekly-description">
<p>Another issue of Increment, on a topic integral to SRE: testing.</p>
<p>It doesn&#8217;t matter if you&#8217;ve already read everything Charity Majors has written; in this article she&#8217;s still managed to find new and even more compelling ways to argue that we should embrace testing in production.</p>
<p>My two other favorite articles from this issue:</p>

<p>This is aimed at Certification Authorities dealing with TLS certificate misissuance issues and the like, but it very much applies to any kind of incident.</p>
<p><strong>BONUS CONTENT</strong>: An <a href="https://groups.google.com/forum/#!topic /mozilla.dev.security.policy/5pPUl-Z6mBM">incident report</a> from LetsEncrypt just a few days later included this gem, exactly in line with what Ryan wrote:</p>
