• What is the cause and solution for SAP error message ABAP_TESTDOUBLE037 - &4 Double cannot be created if all methods in a class are STATIC ?

  The SAP error message ABAP_TESTDOUBLE037 indicates that you are trying to create a test double (a mock or stub) for a class in ABAP, but the class in question has all its methods defined as static. In ABAP, a test double is typically used in unit tests to simulate the behavior of a class or its methods without invoking the actual implementation.
  
  Cause:
  The error occurs because:
  
  A test double cannot be created for a class that has only static methods. Test doubles are designed to work with instance methods, as they rely on the ability to instantiate an object of the class.
  Static methods belong to the class itself rather than to any instance of the class, which makes it impossible to create a test double that can override or simulate the behavior of those methods.
  
  
  Solution:
  To resolve this error, you have a few options:
  
  
  Refactor the Class:
  
  If possible, refactor the class to include instance
