Printing LHS and RHS of assert expressions on failure

[Adnan]

Hi, is there any trick to print the RHS and the LHS of the assert 
expressions when it fails?

like `assert(2 == 5)` should fail and print something like:
... assert failed [__LINE__/__MODULE__]: Left hand side: 2 is 2, 
Right hand side: 5 is 5

Of course, I can design a function to do so myself, but I just 
want to know is there any de-facto way of achieving this?

Is there any unit-testing library that does this for me?
