struct name: User
Field(if nothing type ! and enter): Name
Type: string
Field(if nothing type ! and enter): Age
Type: int64
Field(if nothing type ! and enter): URL
Type: string
Field(if nothing type ! and enter): !

type User struct {
	Name string
	Age  int64
	URL  string
}

func NewUser(

) User {
	return User{
		Name: name,
		Age:  age,
		URL:  url,
	}
}

func TestUser_NewUser(t *testing.T) {
	t.Parallel()

		name string
		age  int64
		url  string
	}
	tests := []struct {
		name string
		in   in
		out  User
	}{
		{
			name: "success",
			in: in{
				name: "name001", age: 15, url: "url001",
			},
			out: User{
				Name: "name001", Age: 15, URL: "url001",
			},
		},
	}
	for _, tt := range tests {
		tt := tt
		t.Run(tt.name, func(t *testing.T) {
			t.Parallel()
			out := NewUser(
				tt.in.name, tt.in.age, tt.in.url,
			)
			assert.Equal(t, tt.out, out)
		})
	}
