[🐞] component not refresh when signal update

[wszgrcy]

Which component is affected?

Qwik Runtime

Describe the bug

I want to use an asynchronous operation to update the signal (similar to setTimeout). However, when updating the value, printing the value is also normal But the rendering is not updated

Reproduction

npm run test.unit

You're using setTimeout on the server to update the signal. This will change the signal after the SSR completed.

Instead you should use a promise, out update the value on the client.

BTW for small repros like this, it's nicer to use https://qwik.dev/playground

How can I determine if the test logs are from the server or client?
I also used button click triggering during testing, but there was no update

I add https://github.com/piying-org/qwik-test/tree/v1 listen change on useTask$ and useVisibleTask$ but not work

Can you help me find out what exactly caused it

on v3

useTask$ and useVisibleTask$ both run on server.Is this a correct return?

I'm sure it should be a bug in the testing environment. It failed in the testing environment But it succeeded in the playground

@wszgrcy sorry for missing this. I don't see a problem here, the tests are running both the server and client versions in the test enviroment.

If you have more questions like this, it's better to ask on the discord. In the meantime, I'll close this.

Maybe it's because I've modified too many versions before, so the description isn't clear enough.
I'm verifying using unit tests, but the execution fails.

I wrote a comment in the project, and if asynchronous is removed here, it will be executed successfully
