I am using shunit2 to test Bash scripts.
I have a script however whose behaviour depends on the special variable $$
. At the moment, my method of verifying its behaviour involves me creating "spies" that expect certain commands to be called. I can't do this here because the commands called depend on the value of $$
.
I have seen answers here and here, as mentioned in comments, but they would require me to go outside of Bash and "hack" Linux as it were. My tests usually run on Mac OS X in any case.
Is there any way to set the value of $$
in a unit test or otherwise "stub" it out?

Oh thanks. I didn't see that although it is a slightly different question and in any case I don't think suggests a way forward for what to do in a unit test. E.g. I can't assume the test environment is Linux, because it's probably Mac OS X etc.

How precisely does value of $$ cause different commands to be run? Are you testing whether it's odd or even? Power of 3? Prime?

Okay, think I might understand. haven't used shunit2. Couple of ideas: 1) wrap relevant assertion actual args to rewrite/filter known unknowns; 2) replace any use of $$ in code with a function that can be mocked
