How can i test my mobile game in unity?

I mean it’s obvious i can’t touch my pc’s screen unless it’s one of those touch screen laptops. I tried remotely connecting to my pc with my phone when in test screen. I couldn’t move or anything. I couldn’t find anything on internet so far except a 25 bucks plugin. Is there a way to test touch inputs via pc or smartphone?
Thanks in advance.

The process differs depending on whether you’re talking about Android/Winphone/iOS, but you certainly don’t need to buy any additional assets. On Android, you simply plug your phone in via USB and click Build and Run. If you’re using the Unity Remote app, you don’t even need to rebuild the project - just click Play in the editor window and it will stream to tour phone. I don’t do iOS development, but I believe the process is a bit more involved.

There’s mobile platform-specific guides here that explain details:
