[boost] [boost.test] Invoking test case from within another case

Hi all, I have built a performance measurement template function that can measure the time that a given piece of code takes to run, as well as provide some statistics such as standard deviation over x iterations etc. I am looking to integrate this into my existing boost.test setup, in a new suite called performance. This works fine if I write new test cases inside the performance test suite that invoke this function, but my goal is to also be able to run preexisting test cases in other suites to measure their performance. It'd be a bit hacky to have to include them again inside the new namespace. Is there a way to invoke a test in a specific test suite from inside another test case? Kind regards, Philip Bennefall
