How to upload game on dropbox for people testing

i have made game for gameJam

i want to share it with people for testing

how to upload preview on dropbox

You can't.

You could upload an APK for them to download and test themselves but you would have to build the APK separately first.

Just put it on the arcade or newgrounds. I'm not sure if there are private settings in there but you could check.

but i have seen that some people share a link which we can open and play directly on desktop browser without any download

Dropbox has changed and doesn't allow public/live linking anymore:

As noted here

Unless you are an existing paid/premium user... then the live linking will finish on 27 September this year. If you are a free user then they stopped that from working already.

then any other option like on google drivevir one drive

does they do this service??

I don't use Google Drive, so I'm not sure about that.

I use a hosting account on my domain to upload tests and things like that.

You can buy a domain and hosting package from places like GoDaddy for a very cheap price if you only need basic options.
