我正在尝试使用Data Dog的go-sqlmock和testify在Go中编写模型单元测试。

我有以下代码：

type Suite struct {
    suite.Suite
    DB *gorm.DB
    mock sqlmock.Sqlmock

    repository      Repository
    user *models.User
}

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 (s *Suite) AfterTest(_,_ string) {
    require.NoError(s.T(),s.mock.ExpectationsWereMet())
}

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

func (s *Suite) Test_repository_Get() {
    var (
        ID        = 1234
        CountryID = 1
    )

    s.mock.ExpectQuery(regexp.QuoteMeta(
        `SELECT * FROM "User" WHERE (id = $1)`)).
        WithArgs(strconv.Itoa(ID)).
        WillReturnRows(sqlmock.NewRows([]string{"ID","CountryID"}).
            AddRow(strconv.Itoa(ID),strconv.Itoa(CountryID)))

    res,err := s.repository.Get(ID)

    require.NoError(s.T(),err)
    require.Nil(s.T(),deep.Equal(&models.User{ID: ID,CountryID: CountryID},res))
}

func (s *Suite) Test_repository_Create() {
    var (
        ID        = 1234
        CountryID = 1
    )

    s.mock.ExpectQuery(regexp.QuoteMeta(
        `INSERT INTO "User" ("ID","CountryID") 
            VALUES ($1,$2) RETURNING "User"."ID"`)).
        WithArgs(ID,CountryID).
        WillReturnRows(
            sqlmock.NewRows([]string{"ID"}).AddRow(strconv.Itoa(ID)))

    err := s.repository.Create(ID,CountryID)

    require.NoError(s.T(),err)
}

但是当我运行TestInit时，出现以下错误：

> call to database transaction Begin,was not expected,next expectation
> is: ExpectedQuery => expecting Query,QueryContext or QueryRow which:
>   - matches sql: 'INSERT INTO "User" \("ID","CountryID"\)             VALUES \(\$1,\$2\) RETURNING "User"\."ID"'
>   - is with arguments:
>     0 - 1234
>     1 - 1
>   - should return rows:
>     row 0 - [1234] [0m

我有几个问题：

1. 这是什么问题？
2. 有没有办法知道SetupSuite函数是否正在运行？
3. 为什么我运行? my-project [no test files]时会得到go test？这是上面代码的文件路径：my-project/test/models/User_test.go
