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
request with just the failing test case (you'll probably want to
pattern it after the tests in
[base.go](https://github.com/go-xorm/tests/blob/master/base.go) AND
[benchmark.go](https://github.com/go-xorm/tests/blob/master/benchmark.go).
request with just the failing test case(you can find some example test file like [session_get_test.go](https://github.com/go-xorm/xorm/blob/master/session_get_test.go)).
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)
If you implements a new database interface, you maybe need to add a test_<databasename>.sh file.
For example, [mysql_test.go](https://github.com/go-xorm/xorm/blob/master/test_mysql.sh)
