<h1 dir="auto">Bug report</h1>
<h2 dir="auto">Describe the bug</h2>
<p dir="auto">Running <code class="notranslate">testonly</code> crashes my computer due to the numerous (50+) Chrome instances it opens for testing.</p>
<h2 dir="auto">To Reproduce</h2>
<ol dir="auto">
<li>Fork a fresh copy of next.js repo</li>
<li>Clone to local machine</li>
<li><code class="notranslate">yarn</code> to install dependencies</li>
<li><code class="notranslate">yarn run bootstrap</code> as state in contributing.md</li>
<li><code class="notranslate">yarn testonly</code></li>
<li>Tests run and open windows and gradually slow down my machine until it crashes and needs restarting.</li>
</ol>
<h2 dir="auto">Expected behaviour</h2>
<p dir="auto">I am not entirely sure whether this is a bug that causes the issue or whether this is something that just needs a warning in contributing.md. I'm running a 2016 15" MacBook pro so hopefully this isn't an issue with not having enough specs.</p>

<p dir="auto">Currently we're using <a href="https://npmjs.com/wd" rel="nofollow">https://npmjs.com/wd</a> / chromedriver which fails at random on Azure Pipelines (Windows), to make the tests as reliable as possible.</p>

So if someone from the community wants to step in and contribute to these feel free to 🙏 it would be much appreciated.

<h2 dir="auto">Additional context</h2>
<p dir="auto">The best way to do this would be to start small and progressively move tests towards the puppeteer implementation, considering we have a lot of tests.</p>
