What I wanted was:</p> <ul> <li>Tests that run against a real VSCode instance, not mocks.</li> <li>An immutable test workspace, so every test starts from the same files.</li> <li>A log file per test, so I can see what the extension did when a test fails.</li> </ul> <h2 class="relative group">Principles <div id="principles" class="anchor"></div> <span class="absolute top-0 w-6 transition-opacity opacity-0 -start-6 not-prose group-hover:opacity-100 select-none"> <a class="text-primary-300 dark:text-neutral-700 !no-underline" href="#principles" aria-label="Anchor">#</a> </span> </h2> <p>Some things I learned the hard way about testing extensions.</p>http://awalsh128.com/vscode-keep-sorted/Thu, 25 Dec 2025 00:00:00 -0800http://awalsh128.com/vscode-keep-sorted/<table width="100%"> <tr> <td width="48"><img src="logo.png" alt="Logo" width="48" height="48"></td> <td style="padding-left:1em"><h1>VSCode Keep Sorted Extension</h1></td> </tr> </table> <div class="admonition relative overflow-hidden rounded-lg border-l-4 my-3 px-4 py-3 shadow-sm" data-type="note"> <div class="flex items-center gap-2 font-semibold text-inherit"> <div class="flex shrink-0 h-5 w-5 items-center justify-center text-lg"><span class="relative block icon"><svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 512 512"><path fill="currentColor" d="M256 0C114.6 0 0 114.6 0 256s114.6 256 256 256s256-114.6 256-256S397.4 0 256 0zM256 128c17.67 0 32 14.33 32 32c0 17.67-14.33 32-32 32S224 177.7 224 160C224 142.3 238.3 128 256 128zM296 384h-80C202.8 384 192 373.3 192 360s10.75-24 24-24h16v-64H224c-13.25 0-24-10.75-24-24S210.8 224 224 224h32c13.25 0 24 10.75 24 24v88h16c13.25 0 24 10.75 24 24S309.3 384 296 384z"/></svg> </span></div> <div class="grow"> Note </div> </div><div class="admonition-content mt-3 text-base leading-relaxed text-inherit"><p>Updated October 2026 for version 1.0.2.
