`使用go sqlmock模拟gorm`updates`时,无法匹配实际sql`错误?

嘲弄
库_test.go

我犯了一个错误
ExecQuery: could not match actual sql: "UPDATE "requests" SET "status" = $1 WHERE (request_id = $2 AND system_id = $3 AND request_type = $4 AND status = $5)" with expected regexp "UPDATE "requests" SET "status" = $1 WHERE ("request_id" = $2 AND "system_id" = $3 AND "request_type" = $4 AND "status" = $5)”
Error Trace: repository_test.go:<line number>
Error: Expected nil, but got: &errors.errorString{s:"ExecQuery: could not match actual sql: \"UPDATE \"requests\" SET \"status\" = $1 WHERE (request_id = $2 AND system_id = $3 AND request_type = $4 AND status = $5)\" with expected regexp \"UPDATE \"requests\" SET \"status\" = $1 WHERE (\”request_id\" = $2 AND \”system_id\" = $3 AND \”request_type\" = $4 AND \"status\" = $5)\""}

repository_test.go:<lineNumber>: there were unfulfilled expectations: there is a remaining expectation which was not matched: ExpectedExec => expecting Exec or ExecContext which:

0 - success
1 - 2

我尝试了,将
ExpectExec
更改为ExpectPrepare().ExpectExec
或mock.ExpectQuery(regexp.QuoteMeta
和其他票证在go-sqlmock问题中提到的其他选项。它们都不起作用。使用此选项已持续2天。请帮助。原因是您没有转义查询字符串的正则表达式。sqlmock期望正则表达式符合您的期望
现在,如果您希望匹配精确的查询字符串,而不是其中的一部分,请执行此操作。
您可以指定sqlmock选项,如下所示:
db, mock, err := sqlmock.New(sqlmock.QueryMatcherOption(sqlmock.QueryMatcherEqual))
答案在文档中,如果您只需阅读一次api文档,这可以节省您的时间
db, mock, err := sqlmock.New(sqlmock.QueryMatcherOption(sqlmock.QueryMatcherEqual))
