How do I fuzz something?

Heyo, I wanted to try and fuzz something using master as of today but failed to use the api correctly. How do I fuzz test a test case?

I managed to get it to work (correctly, as far as I can tell).

The function std.testing.fuzzInput no longer exists. Instead, the user has to wrap the test in a function with the signature fn ([]const u8) anyerror!void and the pass that function to std.testing.fuzzInput. To run, type zig build test --fuzz.

Could you provide a code example?

const std = @import("std");

test {
    try std.testing.fuzz(struct {
        fn testOne(input: []const u8) anyerror!void {
            try std.testing.expect(input.len != 2);
        }
    }.testOne, .{});
}
