A doctest implementation inflates an otherwise empty binary by about 516KB without any optimisation flags on, and by about 155KB with -Os (gcc 9.4, c++11). Of the Arduino AVR boards, only the Mega can fit this (I think the ATmega2650 is the only one that can). The Uno and Nano only have 32KB of program storage.
Even if you addressed the size issue (or it isn't a problem for you), avr-gcc (and the Arduino Core libraries) are going to be missing a lot of functionality from the standard library because there is no need for it on a microcontroller.
Your best bet is to use an alternative that will fit onto and run on a microcontroller (a quick search revealed https://www.arduino.cc/reference/en/libraries/aunit/, I'm sure there are others).
