zig test should offer more flexible inputs

[finleyjb]

It would really be helpful if I could run a command like below to run all tests within the src directory:

zig test src

I'm sure I can come up with the correct grep/find command to do something equivalent to this, but it would really be a lot easier if I could run a command like above.

This problem is already solved by using a nameless test block

test {
    _ = @import("src/test_file_1.zig");
    // ...
    _ = @import("src/test_file_N.zig");
}

I guess #8221 is worth noting here as well if it's a documentation issue.

Though I do still feel it would be nice to have a way to do something like this without having a list of files to maintain. Maybe some kind of comptime function could work? Then I could do something like:

test {
  testSuite("src");
}

This would import every source file within that directory. Maybe some sort of glob syntax so you could do something like:

test {
  testSuite("src/prefix_*.zig");
}

you can do std.meta.refAllDecls(@This()); to reference all constants (basically all imported files).

I see that there's that method in std.meta, but there appears to also be one in std.testing. Is the latter what should be used?

EDIT: It looks like that got moved to testing:

zig/lib/std/meta.zig

Line 848 in 4fc6f63

pub const refAllDecls = @compileError("refAllDecls has been moved from std.meta to std.testing");
