From e09e7f1035fc2a8c918822cbfcfac61c77153497 Mon Sep 17 00:00:00 2001 From: Thomas Graf Date: Thu, 14 Mar 2013 16:25:17 +0100 Subject: [PATCH] tests: Add check based unit test system Introduces new unit tests based on `check`. Each subsystem/module can have its own unit tests in tests/check-.c that will be linked together in tests/check-all.c. Running 'make check' will compile and run the unit tests automatically. A reference unit test implementation has been done for the abstract address module.
