When enabled (set to 1), debugging is enabled. This means the assertion macros are expanded to actual code and not to nothing.

By default, this is set to 0 if NDEBUG is defined and to 1 if NDEBUG is not defined.

If you want to change this value, you have to define this value before including any SeqAn header.

Force-enabled if SEQAN_ENABLE_TESTING is set to 1.
