Re: [boost] [test] unit test command-line handling

...

...and what is the appropriate way to signal an error, such as a missing or unsupported command-line argument ? (All the examples in the docs I could find return '0', so another related question is: what is the meaning of the return value ?)

There is this exception you may throw:

Again, this is not so well documented here:

https://www.boost.org/doc/libs/1_68_0/libs/test/doc/html/boost_test/adv_scen...

I assume throwing setup_error works only with the obsolete init_func? How would it be with the 'new' way described at the caution note on bottom of the last URL. Thanks, Olaf
