• [x] enhancement

What problem(s) does this PR solve?

Issue(s) number: #3224

Description:

This PR enhances the FunctionManagerTest by adding comprehensive test cases for various return type functions. It includes tests for integer, float, string, boolean, and list return type functions, and also covers cases with variable argument types, non-existent functions, and incorrect argument types.

How do you solve it?

• Added multiple test cases in FunctionManagerTest to cover:
  • Integer return type functions like abs
  • Double return type functions like sqrt, ceil, floor, round, cbrt, pow, sin, asin, hypot
  • String return type functions like toString, concat
  • Boolean return type functions like eq
  • List return type functions like split
  • Functions with variable argument types like max
  • Non-existent functions and incorrect argument types to ensure robust error handling

Special notes for your reviewer, ex. impact of this fix, design document, etc:

• This enhancement increases the test coverage and ensures that the FunctionManager handles different return types and argument scenarios correctly.
