Go “错误”；“不应出现查询”；使用sqlmock进行单元测试时的插入

我正在尝试运行一个单元测试来执行对DB的插入，所以我模拟了gorm日志显示的完全相同的查询字符串，使用了相同的参数，但在尝试执行测试时仍然存在问题，（使用postgres驱动程序）因为sql模拟似乎与我在模拟中定义的sql不匹配，并显示如下错误：

"**call to Query** 'INSERT  INTO "customer" ("customer_key","first_name","middle_name","last_surname") VALUES ($1,$2,$3,$4) RETURNING "customer"."customer_key"' with args 
[{Name: Ordinal:1 Value:RLKuxK-wnj8SUn50iFMjsrCtikTLTEmUFP7fOSE2veI=}
 {Name: Ordinal:2 Value:Martín} {Name: Ordinal:3 Value:Constan} 
{Name: Ordinal:4 Value:Smith}] 
**was not expected** "

存储库。转到

。。。
func（r*存储库）寄存器（customer*models.customer）（*字符串，错误）{
错误：=r.db.Create（&customer）。错误
如果错误！=零{
返回零，错误
}
返回customer.CustomerKey，无
}
...

存储库\u测试。开始

func测试寄存器（t*testing.t）{
qStr:=`插入“客户”（“客户密钥”、“名字”、“中间名”、“姓氏”）
值（$1、$2、$3、$4）返回“客户”。“客户密钥”`
t、 运行（“如果给定的客户输入有效，则必须返回新创建的客户密钥”，func（t*testing.t）{
r:=mocks.CustomerModel
mock.MatchExpectationsInOrder（false）
mock.ExpectBegin（）
mock.ExpectQuery（regexp.QuoteMeta（qStr））。
WithArgs（r.CustomerKey、r.FirstName、r.MiddleName、r.LastName）。
WillReturnRows（sqlmock.NewRows（[]字符串{“customer_key”}）.AddRow（r.CustomerKey））
mock.ExpectCommit（）
customerKey，err:=回购寄存器（r）
assert.Nil（t，err）
assert.NotNil（t，customerKey）
})
}

我得到以下错误：

不是预期的。您确定gorm在表/字段名周围使用双引号发送准确的查询吗？检查这些是否为单引号。
