问题 I'm working with a simple component that does a side effect. My test passes, but I'm getting the warning Warning: An update to Hello inside a test was not wrapped in act(...). . I'm also don't know if waitForElement is the best way to write this test. My component export default function Hello() { const [posts, setPosts] = useState([]); useEffect(() => { const fetchData = async () => { const response = await axios.get('https://jsonplaceholder.typicode.com/posts'); setPosts(response.data); }
