We appreciate any bug reports, but especially ones with self-contained

(doesn't depend on code outside of xorm), minimal (can't be simplified
|

further) test cases. It's especially helpful if you can submit a pull

|

pattern it after the tests in

If you implements a new database interface, you maybe need to add a <databasename>_test.go file.

For example, [mysql_test.go](https://github.com/go-xorm/tests/blob/master/mysql/mysql_test.go)
