如何在Golang中测试结构体方法_Golang结构体方法单元测试方法

package main

type User struct {
    FirstName string
    LastName  string
    Age       int
}

func (u *User) GetFullName() string {
    return u.FirstName + " " + u.LastName
}

func (u *User) IsAdult() bool {
    return u.Age >= 18
}

package main

    user := &User{
        FirstName: "John",
        LastName:  "Doe",
    }

    fullName := user.GetFullName()

    if fullName != "John Doe" {
        t.Errorf("期望 'John Doe'，实际 '%s'", fullName)
    }
}

func TestUser_IsAdult(t *testing.T) {
    tests := []struct {
        name string
        age  int
        want bool

    }

    for _, tt := range tests {

}

go test -v
