TinyOS smells even better than I suspected : TUnit

#define assertEquals(msg, expected, actual)\
  if ((expected) != (actual)) {\
    assertEqualsFailed(msg, ((uint32_t) expected), ((uint32_t) actual), unique(UQ_ASSERTION));\
  } else {\
    assertSuccess();\
  }


So this is some holiday!
expected and actual are evaluated twice!
If you put this macro inside some if-else without nesting in {} you will get very funny things!


Why not:

#define assertEquals(msg, expected, actual) ({\
uint32_t e = expected;\
uint32_t a = actual;\
  if (a != e) {\
    assertEqualsFailed(msg, e, a, unique(UQ_ASSERTION));\
  } else {\
    assertSuccess();\
  }\
})


Why?!

How to fix it? - use Contiki.
