Hi,

I need to start a process before the tests run, and terminate it after the tests run. A module with a shared static constructor and shared static destructor sounds like the way of doing this since the constructor is run before main and the destructor after main. However I am using unit-threaded, not for the threads but because it is great for a whole load of other reasons. In fact the threads are becoming a problem.

As far as I can tell main is terminating before all the tests are complete which means the shared static destructor is executing before all the tests are complete.

To test this hypothesis I want to run single threaded. unit-threaded says this is possible using a command line option -s. The question is which command line? dub test doesn't accept it and neither does the dub command creating ut_main.d

I would use Fixture (a class derived form TestCase) here and derive all tests from it. It allows you to start your process before all test in `setup()` Fixture member and terminate it after in `` and probably lets you run the tests simultaneously.

Did you try `dub test -- -s`?

terminate it after in `shutdown()`

Oh f###, that is about the only combination I didn't try. :-(

Thanks. Problem solved. :-)

Not sure about the Fixture proposal, I will research and cogitate further.
