Proper testing method for function in go

go, md5, testing

Solution

You are probably comparing the raw bytes of the hash with the hexadecimal formatted version of a hash. You might want to do something like this:

got := fmt.Sprintf("%034x", myHash("linux"))
want := "00e206a54e97690cce50cc872dd70ee896"
if got != want {
    t.Errorf("got %q, want %q", got, want) 
}

Problem

I'm new to go and started to play around with testing. My method returns a []byte with a md5 hash in it. ``` func myHash(s string) []byte { h := md5.New() io.WriteString(h, s) return h.Sum(nil) } ``` It's working and the hashes look ok, but when I'm testing it with this method: ``` func TestMyHash(t *testing.T) { s := "linux" bf := ("e206a54e97690cce50cc872dd70ee896") x := hashor(s) if !bytes.Equal(x, []byte(bf)) { t.Errorf("myHash ...") } } ``` It will always fail. First I thought it could be some issue with the casting of a string to []byte or vice versa, but after trying ot over and over again I just need to ask here. Can you give me an example how to test my function? Do I miss something necessary? Thanks in advance.
