unit test: apply same test case to different fixtures

[hm567]

I have auto test cases that can take fixtures whose members they access in a
uniform way.

Say   struct F1... Fn

BOOST_FIXTURE_TEST_CASE( test_case1 , F1 ... Fn )
{
  //same code for all Fi
}

Is there a way to do this?

Regards,

1. Make Fi inherit from Fi+1.
2. Use something like this:

template<typename T1,typename T2>
struct FixtureCollector : T1, T2 {};

You can now either implement above using variardic templates or implement macro
that will convert PP sequence into sequence of FixtureCollector<T1,...>:

For example

FIXTURES((T1)(T2)(T3)) should generate:

FixtureCollector<T1,FixtureCollector<T2,T3> >

use it :

BOOST_FIXTURE_TEST_CASE( test_case1 , FIXTURES((T1)(T2)(T3)) )
{
}

Hi
Pressed Send too early.

The question is how to run the test case on T1 then on T2 then .... on Tn ,
on each one separately

In other words, you'd like there to be a
BOOST_FIXTURE_TEST_CASE_TEMPLATE
to complement
BOOST_AUTO_TEST_CASE_TEMPLATE

I must say you left me a bit puzzled. What does it you are trying to do? Run the
same code against different fixtures? Kinda weird, don't you think?

Not really, as far as I can tell.

The different fixtures have the same member names, even if their types are
different
and the test case code uses those member with the same syntax... It's bit
like if the
fixture was a template argument...
