❤️ It's great to see you here! I'm currently available on evenings and weekends for consulting and freelance work. Let's chat about how I can help you achieve your goals.
Last week I was working on a distribution which includes some XS and
also uses Dist::Zilla. I needed to edit a single test, but didn't want
to run the entire test suite after every edit. It wasn't immediately
clear to me how to do this via "dzil test". I asked in #dzil and
within a couple of minutes I got some excellent advice in the form of:
dzil run prove -lv t/my-test.t
If there is no XS in your distribution you can skip the build process and get an even faster test run:
dzil run --nobuild prove -lv t/my-test.t
Many thanks to KENTNL for the tip.

unless this is affected by generated code (or it’s generated) you could just run
prove -lv t/my-test.t no need to run dzil at all. I suspect nobuild means dzil build phase doesn’t run which means code generation doesn’t happen, but I’m not sure.

In this case,
prove -lv t/my-test.t failed with some errors related to the XS code. So, running the tests via dzil was the easier option for me as that “just worked”. Having said that, yes, just running prove will probably be easier in a lot of cases as well, but it’s nice to know that you have some options.

If you are dealing with XS code, you’ll need prove’s -b option instead of -l

Thanks, -b doesn’t seem to work for me. FWIW, I’m working on https://github.com/maxmind/MaxMind-DB-Writer-perl and the error I get from prove directly is “~/MaxMind-DB-Writer-perl ∙ carton exec prove -lvb t/MaxMind/DB/Writer/Tree-record-collisions.t t/MaxMind/DB/Writer/Tree-record-collisions.t .. MaxMind::DB::Writer::Tree object version 0.050004 does not match bootstrap parameter 42 at /opt/perl5.16.3/lib/5.16.3/x86_64-linux/DynaLoader.pm line 213.”
I get that error with -l, -lb and -b. It goes away with “dzil run”, though. This module is also already installed on the system I’m developing on. Not sure if that’s related.

There is a Build.PL in the repository for that dist, so you should be able to simply: perl Build.PL && ./Build && ./Build test – or just perl Build.PL && ./Build && perl -Mblib t/foo.t.
