A Pi is cheap enough that one can simply buy one.  The new 64-bit one runs 32-bit binaries and is significantly faster than a pi2.  As far as testing, one can either connect a display via hdmi and a mouse & keyboard via usb, or use VNC.  There's a guide to setup of raspbian and of the VNC server on raspberrypi.org.
