Question

我是sqlmock的新手。想为下面的功能编写模拟。但我是收到错误消息“未预期会调用查询，下一个期望是：
ExpectedPrepare =>期望Prepare语句：匹配sql“

我需要帮助以了解上述错误的原因。要么我该如何为下面的函数编写模拟？

我的代码看起来与此类似

>>>>>>>>>Request.go<<<<<<<<<<<<<<

type Request struct{
    Username string `gorm:"column:username" json:"USerName"`
    Status string `gorm:"column:status" json:"Status"`

}
func (p *Request) TableName() string {
    return "requests"
}

//function which needs to be mocked
type Repository interface {
    GetRequestDetails(user string)(*Request,error)

}

type repo struct {
    DB *gorm.DB
}

func (p *repo) GetRequestDetails(user string)(*Request,error){
    request := new(Request)
    err := p.DB.Select("*").Where("username = ?", user).Find(request ).Error
    return request,err
}


func CreateRepository(db *gorm.DB) Repository {
    return &repo{
        DB: db,
    }
}


>>>>>>>>>RequestTest.go>>>>>>>>>>>>>>>>>>>>>>>>


type Suite struct {
    suite.Suite
    DB   *gorm.DB
    mock sqlmock.Sqlmock
    repository Repository
    request *Request
}

func (s *Suite) SetupSuite() {
    var (
        db  *sql.DB
        err error
    )

    db, s.mock, err = sqlmock.New()
    require.NoError(s.T(), err)

    s.DB, err = gorm.Open("mysql", db)
    require.NoError(s.T(), err)

    s.DB.LogMode(true)

    s.repository = CreateRepository(s.DB)
}

func TestInit(t *testing.T) {
    suite.Run(t, new(Suite))
}

//testing function
func (s *Suite) Test_repository_Get(){
rows := sqlmock.NewRows([]string{"username", "status"}).
        AddRow("post 1", "hello").
        AddRow("post 2", "world")
    s.mock.ExpectPrepare("SELECT * FROM requests WHERE username = ?").ExpectQuery().WithArgs("post 1").WillReturnRows(rows)
    res,_ := s.repository.GetRequestDetails("post 1")
    require.NoError(s.T(), err)
    fmt.Println(res)

}

出现错误，但原因是什么？如何修改上面的实现以使其起作用

谁能告诉我如何使用sqlmock模拟下面的函数
