UnitTesting Module in Mendix 7

We are currently running Mendix 7.2.0 and when we try to import the UnitTesting module, we get quite a few Java compilation errors firstly that 'package objecthandling does not exist', and then a lot of errors referencing a function 'XPath.create()'. Has anyone else run into this, and is there something I'm missing? We had this same issue in Mendix 7.1.1, for what it is worth.
