Jumping to (wrong) conclusions again. He said "when one (meaning a
battery) fails." He didn't say when the unit fails the test.

In fact the battery going out is what causes the unit to fail the test.
The unit test is primarily a battery test. As far as I know there is no
way to test the detector, except of course to build a fire under it.
