Accepted Proposal

Zig version

0.11.0-dev.109+a2e67173d

As today, if we have a source:

test "read" {
...
}

test "read struct" {
...
}

We can't run single test case read with zig test file.zig --test-filter "read". It will run both tests. There is no way to run specific test.

Proposal

Option 1:

--test-filter will use pattern matching (glob or wildcard will be sufficent). For now it uses std.mem.indexOf. It would be breaking change maybe (--test-filter not used in compiler tests i think, only for user code). And will require to write a pattern matching code in stdlib.

Option 2:

Add another option to specify exact test case to run: --test-name or --test-case. It would be non breaking and easy to achieve.

Any ideas welcome.

Option 3

Write simple wildcard matching in src/test.zig, or use reference code. I prefer this option, i can even try open pull request for that.
