.. data:: FAIL_FAST
When specified, exit after the first failing example and don't attempt to run
- the remaining examples. Thus, the number of failures reported will always be 1.
- This flag may be useful during debugging, since examples after the first
+ the remaining examples. Thus, the number of failures reported will be at most
+ 1. This flag may be useful during debugging, since examples after the first
failure won't even produce debugging output.
