Is it good practice to use the weak attribute in production code so that for test code one can override functions?

I suggest you check the Stack Exchange Q&A site on [Software Quality Assurance and Testing](http://sqa.stackexchange.com/), maybe you will find it helpful. – codeaviator Mar 07 '16 at 08:34

I don't know if it is good practice, but there are ways to override functions in test code that do not interfere with production code:

using macros that redefine the function names you wish to override
using LD_PRELOAD
using macros that expand to __weak in debug mode and to nothing in production mode.
