How to use class in SOAPUI

Hi,

I want to write a class with groovy. The class " X" will contain function A, B, and C. I want to use these functions in the test steps for assertion or other purpose (for example split a string). How can I achieve this?


1) How to import class "X" in SOAPUI so that I can invoke methods from different test steps?
2) How to call the function A, B or C from the test steps?


Thanks for your response!!
