CF2018 unit test framework

[taocui]

We have migrated CF11 to CF2018, however the unit tests are no longer working anymore. The error message is shown below. I am wondering if anyone else has the similiar issue.

The value returned from the getTests function is not of type array.
If the component name is specified as a return type, it is possible that either a definition file for the component cannot be found or is not accessible. The error occurred in D:/Solutions/frst/UnitTests/net/sourceforge/cfunit/framework/TestSuite.cfc: line 133
