<p>I recently made a change to a Drupal project with several custom modules.</p>
<p>As part of the change, there was a method that was no longer being used, so I went ahead and removed it.</p>
<p>There were no tests for this part of the codebase, and the existing tests were still passing.</p>
<p>My change was successfully finished and deployed, including removing the unused method.</p>
<p>A few days later, we noticed cron jobs were no longer running on the website.</p>
<p>The method I'd removed was attempting to be called from within a different module.</p>
<p>Because it no longer existed, it was causing an error and stopping the cron job from running successfully.</p>
<p>When I re-added the method, the cron jobs worked again.</p>
<p>There were no <code>dependencies</code> set in either module's .info.yml file, though that would only prevent you from uninstalling either module.</p>
<p>It wouldn't prevent me from deleting code used by another module.</p>
<h2 id="here%27s-the-thing">Here's the thing</h2>
<p>This is why I've been <a href="/daily/2024/02/08/experimenting-with-architectural-testing">experimenting with architectural testing</a>. To ensure that modules only use their own code and to start enforcing layers within each module.</p>
<p>Then, if I had the same situation again, I'd know straight away that there was an issue and not have to wait for the bug to be deployed to production.</p>
