Question

I want to extensively test some pieces of C code for memory leaks.

On my machine I have 4 Gb of RAM, so it’s very unlikely for a dynamic memory allocation to fail. Still I want to see the comportment of the code if memory allocation fails, and see if the recover mechanism is “strong” enough.

What do you suggest ? How do I emulate an environment with lower memory specs ? How do i mock my tests ?

EDIT:
I want my tests to be code independent. I only have “access” to return values for different functions in the library I am testing. I am not supposed to write “test logic” inside the code I am testing.

Answer 1

To do this code independently, I’d suggest using a virtual machine with a much smaller memory setting and running your code within that. Otherwise, you are left with testing on actual systems with smaller memory configurations.
