Golang - Do i have to test structs?

I was wondering. If i have to test content of structs.

Example test:

package main

import "testing"

func TestRegisterTokenRequest(t *testing.T) {
    r := registerTokenRequest{
        UID:      12332,
        FcmToken: "Super responsive Token",
    }

    if r.UID != 12332 || r.FcmToken != "Super responsive Token" {
        t.Error("registerTokenRequest does not match expected.")
    }
}

Actual file:

package main

import (
    "encoding/json"
    "io"
    "log"
    "net/http"

    "firebase_handler/db"
    "firebase_handler/models"
)

type registerTokenRequest struct {
    UID      int    `json:"uid"`
    FcmToken string `json:"fcm_token"`
}

Tests pass. But when i run go test -cover, i get:

go test -cover
PASS
coverage: 0.0% of statements
ok      firebase_handler        0.010s

Should it be at least at 1%( there are ~ 200 lines of code in the package ).

Thanks!
