I've been setting up CI tests and OSX and Linux tests are good
to go thanks to Travis. I'm having a little more difficulty
with testing on Windows via AppVeyor, since DMD is too
memory-hungry to `dub test` without a fatal error when DMD was
compiled for a 32-bit target as opposed to 64-bit, as is the
case for all Windows releases.
How can I compile and run unit tests for only a part of the
library at a time, so that 32-bit Windows can run tests too?
(Which is actually important, since there are different x86 and
x86-64 implementations of some library functions.)
If there was a 64-bit DMD for Windows (not available AFAIK),
you'd simply compile with `-m32` or `-m32mscoff`.
Or is there another solution? It's my understanding that phobos
would have a similar problem if it didn't do something
deliberate with how tests are run.
Definitely; there are various Phobos modules requiring more than
2 GB of memory when compiled with `-unittest` (at least when
emitting 64-bit code). That's why they are compiled separately; I
once tried compiling all of them at once, and that took something
like 30 GB IIRC. ;)
