This seems more appropriate right now for being a question in a help forum, rather than an issue with jest-dom. At the very least, I'd expect a minimal reproducing sample (e.g. a small repo with a react component and a test that fails, so others could reproduce). I do not even know what Signalr is, and for all we know, this could be an issue caused by either Signalr, the combination of it with jest-dom, or even an issue caused by your own code when using both. Don't know.

My suggestion: post this in the repo discussions, or in StackOverflow. And wherever you end up posting it, add more details.

If the results from that show that jest-dom is at fault or could do something better to support your use case, then come back with those details and actionable things to do on our end.

Thanks!
