【问题描述】:
我正在 Go 中设置 testing。我使用go-sqlmock 来测试mysql 连接。现在我尝试测试 mysql insert 逻辑。但是发生了错误。
我想知道如何解决这个错误。
server side: golang
db: mysql
web framework: gin
dao.go
func PostDao(db *sql.DB, article util.Article, uu string) {
ins, err := db.Prepare("INSERT INTO articles(uuid, title,content) VALUES(?,?,?)")
if err != nil {
log.Fatal(err)
}
ins.Exec(uu, article.TITLE, article.CONTENT)
}
dao_test.go
func TestPostArticleDao(t *testing.T) {
db, mock, err := sqlmock.New()
if err != nil {
t.Fatalf("an error '%s' was not expected when opening a stub database connection", err)
}
defer db.Close()
mock.ExpectExec("^INSERT INTO articles*").
WithArgs("bea1b24d-0627-4ea0-aa2b-8af4c6c2a41c", "test", "test").
WillReturnResult(sqlmock.NewResult(1, 1))
article := util.Article{
ID: 1,
TITLE: "test",
CONTENT: "test",
}
PostDao(db, article, "bea1b24d-0627-4ea0-aa2b-8af4c6c2a41c")
if err := mock.ExpectationsWereMet(); err != nil {
t.Errorf("there were unfulfilled expections: %s", err)
}
}
我希望 go test -v 可以正常运行。
但实际并非如此。
这是错误。
=== RUN TestPostArticleDao
2019/08/31 00:08:11 call to Prepare statement with query 'INSERT INTO articles(uuid, title,content) VALUES(?,?,?)', was not expected, next expectation is: ExpectedExec => expecting Exec or ExecContext which:
- matches sql: 'INSERT INTO articles(uuid, title,content) VALUES(?,?,?)'
- is with arguments:
0 - bea1b24d-0627-4ea0-aa2b-8af4c6c2a41c
1 - test
2 - test
- should return Result having:
LastInsertId: 1
RowsAffected: 1
exit status 1
FAIL article/api/dao 0.022s
【问题讨论】:
-
错误非常明显。它期待一个 Exec,但得到了一个 Pepare。您需要哪些方面的帮助?
-
@Flimzy 我想解决这个错误并让这个测试成功。
-
显然你想修复它。问题是除了阅读错误信息之外,您还需要什么帮助?
