I did search all the issues.But this issue doesn't seem have been resolved.

When a large class with 2000+ lines is added to @prepareForTest, the following error is encountered:

The UtilityClass consists of 2300 lines of code. There are static methods inside the class that needs to be accessed. So, I need to add the class to @prepareForTest.

Anyone knows how to fix this issue?
