When using waitFor when Jest has been configured to use fake timers then the waitFor will not work and only "polls" once. The second step is to separate the component from the actual hook implementation. I had a look at how other testing-librarys solve it and it seems like they check if jest fake timers are set and run different logic here, while also capturing the global timer functions before they are overridden and then use these in their waitFor implementation. waitFor,} from '@testing-library/dom' // adds special assertions like toHaveTextContent import '@testing-library/jest-dom' function getExampleDOM {// This is just a raw example of setting up some DOM // that we can interact with. return value from render is not "wrapping" anything. If you want to get more familiar with these queries, you can try them out on for each character as well. query type to see available options, e.g. case above), but it can also confuse screen readers and their users.
