test: when test-filter text-key is contained in filename, all cases ran

[mindon]

Zig Version

0.13.0-dev.73+db890dbae

Steps to Reproduce and Observed Behavior

zig test hello.zig --test-filter hell

// hello.zig
const std = @import("std");

test "hell" {
  try std.testing.expect(true);
}

test "world" {
  try std.testing.expect(false);
}

here the hello.zig filename contains the text hell

Expected Behavior

run only test case hell

Since https://github.com/ziglang/zig/pull/19079, --test-filter works on fully qualified names, so this is intentional.

I believe the fully qualified name of the hell test in your case would be hello.test.hell, so if you want to specifically run tests named hell, you can filter for test.hell.

@squeek502 Is there (a plan to add) some way to list all found/executed tests? I'd imagine a zig test --list with sorted output would be useful in trying to figure out why a test was/wasn't run, finding typos etc.

Since #19079, --test-filter works on fully qualified names, so this is intentional.

i see. the filename.test. is an inclusive prefix for all test names --test-filter.

maybe the docs should be updated to make this intentional idea more obviously ;-p

btw, should the directory part of the file path be inclusive too? i mean this case zig test say/hello.zig --test-filter hell
