unit test: apply same test case to different fixtures

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 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: For example FIXTURES((T1)(T2)(T3)) should generate: FixtureCollector > use it : BOOST_FIXTURE_TEST_CASE( test_case1 , FIXTURES((T1)(T2)(T3)) ) { } Gennadiy

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 Rds,

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 In Christ, Steven Watanabe

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. Gennadiy

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... regards,
