digitalmars.D.learn - Specifying which Phobos modules to unittest

reply Joseph Rushton Wakeling <joseph.wakeling webdrake.net> writes:
Hello all,

Is there any way to specify individual Phobos modules to unittest when
building, 
instead of having to do the whole lot?

When working on 1 single module, it'd be nice to be able to unittest that one 
alone and not have to worry about doing the complete set of tests until ready
to 
push back to GitHub.

Can anyone advise?

Thanks & best wishes,

the tests are not executed at compile time but instead at runtime before 
main(). so you have to compile the modules seperately, and only the 
modules you want to test with the unittest flag.
that means:
dmd -c module1.d module2.d module3.d
dmd -c -unittest module_with_tests.d
dmd module1.o module2.d module3.o module_with_tests.o

when you run your linked program your should only get the unittests from 
moduel_with_tests.

[...]

This is not true of Phobos; the Phobos makefile has a separate rule for
building (and running) unittests. The OP's question is, how to make this
run only a single module's tests as opposed to the entire Phobos (which
takes a while, since some of the tests are quite extensive).

I believe that it's possible. I think that Andrei does it (he posted commands 
related to that at one point, but I couldn't get them to work), but I don't 
know how. I just always run the whole test suite. This is a question that 
would probably be better asked on either the main list or the Phobos list, 
since the ones most likely to know are Phobos devs, and a number of them do 
not pay attention to D.Learn.

compile your module with an empty main (that is what the makefile 
does)

or

rdmd --main mymod.d -unittest

a guaranteed-fail unittest; no result. :-(

mm I've been using this beast for ages with great success.

rdmd --main -unittest std\regex.d

may it be that -unittest should go first?
