Matthew Heath (Nov 29 2024 at 17:58): Matthew Heath (Nov 29 2024 at 17:58):I am trying to add tests to a Zig file towards this PR. But zig test <filepath> doesn't work because there is no platform supplying roc_alloc. What is the simplest way to run such tests
Brendan Hansknecht (Nov 29 2024 at 18:56):Hmm...we provide testing versions of the allocator in the utils.zig file which should be loaded. That is how list tests work despite depending on roc_alloc
Matthew Heath (Nov 29 2024 at 19:10):Whatever I am doing wring also applies to list.zig

Oh is it setting DEBUG_TESTING_ALLOC to true in utils?
Matthew Heath (Nov 29 2024 at 19:16):no... that's just providing console output
Brendan Hansknecht (Nov 29 2024 at 19:23):Hmm, those 3 symbols shouldn't be used anywhere in the zig tests
Brendan Hansknecht (Nov 29 2024 at 19:24):They may not have a testing version created
Matthew Heath (Nov 29 2024 at 19:26):The relevant value seems to be builtin.is_test where builtin = @import("builtin");
Brendan Hansknecht (Nov 29 2024 at 19:27):zig build test should work for you
Brendan Hansknecht (Nov 29 2024 at 19:27):Or I guess zig test if you tell it to link libc
Brendan Hansknecht (Nov 29 2024 at 19:27):I think everything is wired correctly for adding testing allocators and such, but they depend on libc
Matthew Heath (Nov 29 2024 at 19:36):zig build test fails because it can't find a build.zig file.
I think maybe I am just running these commands from the wrong folder
Matthew Heath (Nov 29 2024 at 19:37):hmm--this is at least something else

I think you're on the wrong version of zig. We're still on 0.11.0
Luke Boswell (Nov 29 2024 at 20:15):They changed the way paths were done in later versions, so this is what makes me think that, 38: error: no field named 'path' in union 'Build.LazyPath'
Matthew Heath (Nov 29 2024 at 21:56):More specifically, I was in the wrong terminal. Thanks
