Question

我有一些Go测试，我正在尝试正确使用Null *，但是测试是错误的，我不确定是什么问题。

以下是错误消息：

go test ./...

以下是测试：

package entities

import (
    // "database/sql"
    // "github.com/go-sql-driver/mysql"
    "github.com/stretchr/testify/assert"
    "testing"
    "time"
)

var (
    email          = "leebrooks0@gmail.com"
    hashedPassword = "password"
    firstName      = "Lee"
    lastName       = "Brooks"
    gender         = Male
    dateOfBirth    = time.Now
    height         = 1.85
    currentWeight  = 101.3
)

func privacyConcernedUser() *User {
    user := new(User)
    user.Email.String = email
    user.HashedPassword.String = hashedPassword
    user.FirstName.String = firstName
    user.LastName.String = lastName
    return user
}

func normalUser() *User {
    user := privacyConcernedUser()
    user.Gender.String = gender
    user.DateOfBirth.Time = dateOfBirth
    user.Height.Float64 = height
    user.CurrentWeight.Float64 = currentWeight
    return user
}

func TestSignUpPrivacyConcernedUser(t *testing.T) {
    user := privacyConcernedUser()
    user.SignUp()

    checkMandatoryValues(t, user)

    assert.Nil(t, user.Gender.String)
    assert.Nil(t, user.DateOfBirth.Time)
    assert.Nil(t, user.Height.Float64)
    assert.Nil(t, user.CurrentWeight.Float64)
}

func TestSignUpNormalUser(t *testing.T) {
    user := normalUser()
    user.SignUp()

    checkMandatoryValues(t, user)

    assert.Equal(t, User.Gender.String, gender)
    assert.Equal(t, User.DateOfBirth.Time, dateOfBirth)
    assert.Equal(t, User.Height.Float64, height)
    assert.Equal(t, User.CurrentWeight.Float64, currentWeight)
}

func checkMandatoryValues(t *testing.T, user *User) {
    assert.Equal(t, User.Email.String, email)
    assert.Equal(t, User.HashedPassword.String, hashedPassword)
    assert.Equal(t, User.FirstName.String, firstName)
    assert.Equal(t, User.LastName.String, lastName)
    assert.NotNil(t, User.CreatedAt.Time) // TODO: Should rather check for not empty
}

更新：用户类型在哪里？

type User struct {
    Id             sql.NullInt64
    Email          sql.NullString
    HashedPassword sql.NullString
    RoleId         sql.NullInt64
    FirstName      sql.NullString
    LastName       sql.NullString
    Gender         sql.NullString
    DateOfBirth    mysql.NullTime
    Height         sql.NullFloat64
    CurrentWeight  sql.NullFloat64
    CreatedAt      mysql.NullTime
    ConfirmedAt    mysql.NullTime
    LastActivityAt mysql.NullTime
    DeletedAt      mysql.NullTime
}

func (u *User) SignUp() {

}

对于此错误：

app/entities/user_test.go:34: cannot use dateOfBirth (type func() time.Time) as type time.Time in assignment

您似乎正在尝试将函数time.Now分配给time.Time字段。想必你要调用这个函数吗？

对于这些错误：

app/entities/user_test.go:58: User.Gender undefined (type User has no method Gender)
app/entities/user_test.go:59: User.DateOfBirth undefined (type User has no method DateOfBirth)
...

当你真的想要检查变量User时，看起来你正试图访问user类型的字段（注意案例差异）。

最后，如果您要使用sql.Null*字段创建示例数据并希望它类似于实际数据，则应该将Valid字段设置为true，这样您就不会绊倒实际检查NULL值的代码。

Golang在测试中使用Null * s
