How to Build and Test your Unity Game
The Unity Engine comes equipped with the ability to launch your games to be playable for testing. All you need to do is mess around a bit in the Build Settings. From there, you can share the project in its current form with beta testers, family members, friends, whomever!
To access the Build Settings, go to File > Build Settings.
Switch to the correct Target Platform for your computer.
Click the Build button. Select the Folder that you would like to build it in. In my case, I’m using the Windows Playable Build folder. You can also create a new folder and name it as you desire.
Now if you open the Build, it’ll launch the game.
