They start with : Treadmills to push your exercise tolerance and aim at a target heart rate and your tolerance of the exercise. There are echo and nuclear medicine variations to look at functional and vascular aspects and determine the need for more invasive test or not.

What happens during a stress test for the heart?

Depends: It depends on which type of stress test is done. If you are able, you will probably walk on a treadmill. If not, a medication will be injected into your vein. The doctor will examine your ekg and some pictures of your heart obtained by injecting slightly radioactive material into your vein. Sometimes, an echocardiogram is done instead of the injection.

EKG during exercise: Ekg's are taken at rest and during exercise and recovery. Certain ekg abnormalities are suggestive of blocked arteries to the heart. If these changes occur, the test is positive and is stopped. If the predetermined heart rate is reached without abnormalites, the test is negative. If the goal heart rate is not achieved the test is non-diagnostic. It is a test for blockage of arteries to the heart.

I agree, except for the term "blockage". While arteries do close from plaque rupture & clots, called coronary artery thrombosis, the whole point is to catch advanced disease BEFORE the heart arteries have closed; while just severely narrowed & opening (or bypassing during open chest surgery on heart+lung bypass) these narrowings can improve blood flow, preventing additional heart muscle damage.
