The test is based on a brilliant observation made by Dr. Ames. He realized that there is a strong linkage between the ability to cause mutations in DNA and the ability to cause cancer. To simplify what is an incredibly complicated process, the more mutations that something creates (or, the more mutagenic it is) the more likely it is to cause cancer. Fewer mutations = less cancerous.
