当我尝试使用 SQLMock 和 Gorm.io 模拟 Postgres 插入时，我收到一个错误，表明查询不是预期的。我试图用它regexp.QuoteMeta()来包装和转义我的字符串，但它不起作用。我添加并删除了args和结果，但错误仍然出现

如何通过 SQLMock 设置预期的查询？

我给你原始的 PostgresQuery 和 UserModel

//RAW QUERY
INSERT INTO "users" ("id","name","surname","birthdate","company","custom_claims","deleted") VALUES ($1,$2,$3,$4,$5,$6,$7)' with args [{Name: Ordinal:1 Value:my_user_id} {Name: Ordinal:2 Value:<nil>} {Name: Ordinal:3 Value:<nil>} {Name: Ordinal:4 Value:<nil>} {Name: Ordinal:5 Value:<nil>} {Name: Ordinal:6 Value:<nil>} {Name: Ordinal:7 Value:<nil>}]

//Gorm model
type User struct {
    ID           string `gorm:"primaryKey"`
    Name         *string
    Surname      *string
    Birthdate    *time.Time
    Company      *string
    CustomClaims *json.RawMessage
    Deleted      gorm.DeletedAt
}

func (repository Repository) CreateUser(user users.User) (*users.User, error) {
    newUser := toRepositoryModel(user)

    err := repository.db.Create(newUser).Error //db -> *gorm.DB

    //....
}

//TEST
const expectedQuery = `INSERT INTO "users" ("id","name","surname","birthdate","company","custom_claims","deleted") VALUES ($1,$2,$3,$4,$5,$6,$7)' with args [{Name: Ordinal:1 Value:my_user_id} {Name: Ordinal:2 Value:<nil>} {Name: Ordinal:3 Value:<nil>} {Name: Ordinal:4 Value:<nil>} {Name: Ordinal:5 Value:<nil>} {Name: Ordinal:6 Value:<nil>} {Name: Ordinal:7 Value:<nil>}]`
suite.mock.ExpectQuery(regexp.QuoteMeta(experctedQuery)) //HOW SHOULD BE MODIFIED?
user, err2 := postgres.CreateUser(users.User{
   ID: ID,
})

我已经成功了。

suite.mock.ExpectExec(regexp.QuoteMeta(`INSERT INTO "users" ("id","name","surname","birthdate","company","custom_claims","deleted") VALUES ($1,$2,$3,$4,$5,$6,$7)`)).WithArgs(ID, nil, nil, nil, nil, nil, nil).WillReturnResult(sqlmock.NewResult(0, 1))

更新

Postgres 选择：

//Simulate returned row(s)
userMockRows := sqlmock.NewRows([]string{"id", "name", "surname", "birthdate", "company", "custom_claims", "deleted"}).AddRow(ID, nil, nil, nil, nil, nil, nil)

//Expect SELECT
suite.mock.ExpectQuery(regexp.QuoteMeta(`SELECT * FROM "users" WHERE id = $1`)).WithArgs(ID).WillReturnRows(userMockRows)

Postgres更新：

suite.mock.ExpectExec(regexp.QuoteMeta(`UPDATE "users" SET "name"=$1,"surname"=$2,"birthdate"=$3,"company"=$4,"custom_claims"=$5,"deleted"=$6 WHERE "id" = $7`)).WithArgs(newName, nil, nil, nil, nil, nil, ID).WillReturnResult(sqlmock.NewResult(0, 1))
