By "test initialization", do you mean before the first test starts?
The argc/argv are available to the master test suite:

In 1.68, it is also possible to use this for data driven test cases,
using the make_delayed (if you need a test generator that is dependent
on your argc/argv).

I am surprised I did not create a doc entry about this. The way it works
is indicated in the change logs of boost.test:

Anything after -- is passed to the master test suite argc/argv and is
available to your test module.

I will update the doc on the two points above to make it clearer.
