[Boost-users] [test] Passing parameters to fixtures

Hello,

to set up and tear down database connections for unit tests, I need 
something like parametrized test fixtures.

Up to now (using an old version of Boost.Test) I was creating a customized 
test suite (by deriving from test_suite) and performed the connection 
handling during construction/destruction of the customized test suite.

As the latest Boost.Test now has explicit support for test fixtures, I was 
looking at how I could replace my old approach by using a test suite fixture.

The fixture would need to look something like this:

struct F {
   F(string db_name) { connect to db_name }
   ~F() { disconnect from db_name }
};

Now, the Boost.Test documentation tells me that a fixture is supposed to be 
used like this: BOOST_FIXTURE_TEST_SUITE( s, F )

So there doesn't seem to be a way of passing parameters to the constructor 
of the fixture. Is there any? Or is there any other way to obtain a 
parametrized fixture? Or should I just keep on using customized test suites?

TIA, Markus
