안녕하세요 :)
이 error가 나는 경우는 어떻게 하면 되나요?&nbsp;
<pre class="language-javascript"><code>A worker process has failed to exit gracefully and has been force exited. This is likely caused by tests leaking due to improper teardown. Try running with --detectOpenHandles to find leaks.</code></pre>

오~ 해봐야겠네요. 감사합니다!&nbsp;

안녕하세요 ~~ !!!&nbsp; 
혹시&nbsp; &nbsp;package.json 에서&nbsp;
스크립트 부분에&nbsp;
<div style="color: #eeffff; background-color: #263238; font-family: Menlo, Monaco, 'Courier New', monospace; font-size: 12px; line-height: 18px; white-space: pre;">
<div>"test": "jest --runInBand --detectOpenHandles"</div>
<div></div>
</div>
이렇게 해줘보시겠나요 ~ ?
