Alice: Sorry about this, Stevie.
Carlos Olivera: Just promise me one thing. When you get down there.
Alice: Consider it done.
Alice: Good thing we like a challenge.
Alice: We fought the infection. We survived the apocalypse. And now, we face extinction.
White Queen: Alice. Good luck.
Chase: Climb the Eiffel Tower with a high-powered rifle. A few years ago, that would've caused a stir. Well... Let the good times roll.
Chosen answer: The reason that the cloned alices were put through the tests was their attempt to get a "perfect" clone of her. They knew that Alice was the key to taking back the zombie infestation, so they were trying to get the "perfect" clone. The perfect clone would have all of her memories and reactions, so they put the clones through that testing facility. If she made it out alive, then she was the perfect clone. If she didn't, then it was back to the drawing board.
