Your database test.mdf is corrupt. If you have a backup, then just restore with that backup. If you don't, then you may use REPAIR_REBUILD or REPAIR_ALLOW_DATA_LOSS parameters in DBCC CHeckdb to try to fix the corruption. Note you must make a backup of your current Test.mdf before calling these parameters.
There are also some online resources discussing about this situation, for example:

Good luck!
