This only tests that the Host header is not part of the Header object but it does not test whether the custom value was actually set. I think for this you have to compare the r.Host with the custom host header. Maybe like this:
for k, v := range tt.header {
expectedHeader[k] = v
}
// the Host header is in r.Host and not in the headers
host := expectedHeaders.Get("Host")
if host != "" && host != r.Host {
w.WriteHeader(999)
return
}
expectedHeaders.Del("Host")
