Boost.Test "Expected failures" feature allows developer to specify that 
specific test case supposed to have this number of failures (IOW developer 
knows about the issue and doesn't want test case failure to be reported for 
now). Any other number of assertion failures (more or less) cause test case 
to fail. Be aware though: unless you are using TDD practice of one assertion 
per test case it could be quite dangerous to use this feature on permanent 
basis. Consider what will happened when after your change once assertion 
that supposed to fail is not failing anymore, while another one that 
shouldn't does? Most probably you will never notice that (since the test 
case will pass). So use it with caution ant preferably for temporary 
purposes.
