How is Muscular Dystrophy tested for?

In the 1860s, descriptions of boys who grew progressively weaker, lost the ability to walk, and died at an early age became more prominent in medical journals. In the following ten years, French neurologist Guillaume Duchenne gave a comprehensive account of 13 boys with the most common and severe form of the disease (which now carries his name - Duchenne muscular dystrophy). It soon became evident that the disease had more than one form, and that these diseases affected males of all ages. Nine diseases including Duchenne, Becker, limb girdle, congenital, facioscapulohumeral, myotonic, oculopharyngeal, distal, and Emery-Dreifuss are always classified as muscular dystrophy.

How can two unaffected people have a child who has Duchenne muscular dystrophy?

This is exactly how DMD is transmitted: the defect resides on the X chromosome. Women have 2 X chromosomes, so even if one of the X chromosomes has the DMD trait, the other X chromsome does not and they never get DMD. This is why boys exclusively get Duchenne - they have only one X chromosome. So if a woman carries the Duchenne trait, there is a 50% chance that she will pass DMD to her male offspring. Similarly, there's a 50% chance that her daughters will become carriers like her.
