Unable to create test cases

Hello Matt,
Could you solve this problem? i could not able to write test cases. it throws:
Unable to combine written test code for AssignController.uploadlassAssign(int, MultipartFile, Openconnection) into existing test class TestAssignController This can occur when the existing test file has been manually edited causing an incompatibility. See the documentation for details

Hi Samson,

Would it be possible to send the Diffblue log file please?

Jane @ Diffblue
