Or Death Valley [1]. I've always been of the opinion that this is not just a technical challenge but also a people challenge. Living in an environment that requires pressurized compartments will lead to devastating outcomes if there is even one emotionally unstable or compromised person present. All of the previous biodome experiments on earth have failed for a myriad of technical and people issues. To your point I can't even imagine testing this on Mars. What I could see would be robots setting up an environment for humans ahead of time, constantly measuring life-support status of every compartment and chaos-testing everything constantly to prove that anyone could live there even if they tried to mess it up and let that run for a decade while constantly making improvements.
