go-fuzz-build: `could not find any fuzz functions`

[xaionaro]

I'm trying to do step-by-step it by instruction, but I get error could not find any fuzz functions, instead.

[xaionaro@void fit]$ go-fuzz-build
could not find any fuzz functions in experimental/xaionaro/pcr0/pkg/uefi/fit
[xaionaro@void fit]$ cat get_entries_fuzz_test.go 
// +build gofuzz

package fit_test

import (
        fianoUEFI "github.com/linuxboot/fiano/pkg/uefi"

        . "experimental/xaionaro/pcr0/pkg/uefi/fit"
)

func Fuzz(firmwareBytes []byte) int {
        firmware, err := fianoUEFI.Parse(firmwareBytes)
        if err != nil {
                return 0
        }

        _, err = GetEntries(firmware)
        if err != nil {
                return 0
        }

        return 1
}

Put your Fuzz function in a non-_test.go file. You can use build tags to prevent it from being compiled in regular builds.

It helped. Thank you.
