Does builtin.fuzz imply builtin.is_test?

Help

I’ve written the following. Just wondering if that’s the right way or can i exclude fuzz? Surely not right?

if (builtin.is_test or builtin.fuzz or builtin.mode == .Debug)
    @memset(c.get_blocks(r), @splat(0xFF));

afaik, yes! fuzzer is implemented as a dynamic library that is linked to the test runner which exports a fuzz runner api.

I think you could get fuzzing outside zigs test system, but that would be sketchy and rarely ever needed. You’d probably opt for a custom test runner first.

Thanks. Makes sense and good to know.

I did try using testing.Smith with AFL and not inside of a test block. But the compiler didn’t allow it. So I created a custom, similar AflSmith.
