Don't know what database you are using, but this looks like you are trying
to cast the string 'testing' to an integer and the database engine says you
can't do that.

Does this work instead:
table.update().values(empno = cast(table.c.empno,Integer)).execute()
ie. a bare 'empno' inside your cast expression is just referring to a python
variable 'empno', which you've probably set to the value 'testing' at some
other point in your code. You need the column
