you can just do something like

if (!font_exits)
  return;

in your test function, maybe ?

That would pass the test.  Running a test suite, getting "100 out of 100 passed" while in reality none of the tests were run is less than ideal to say the least.

in Clutter's conformance test suite I have this macro:

#define TEST_CONFORM_SKIP(CONDITION, NAMESPACE, FUNC)   G_STMT_START {  \
  if (CONDITION) {                                                      \
    g_test_add ("/skipped" NAMESPACE "/" #FUNC,                         \
                TestConformSimpleFixture,                               \
                shared_state, /* data argument for test */              \
                test_conform_simple_fixture_setup,                      \
                test_conform_skip_test,                                 \
                test_conform_simple_fixture_teardown);                  \
  } else { TEST_CONFORM_SIMPLE (NAMESPACE, FUNC); }     } G_STMT_END

http://git.gnome.org/browse/clutter/tree/tests/conform/test-conform-main.c#n63

with test_conform_skip_test() being just an empty function. this guarantees that the final report still mentions the skipped test units, under the /skipped path.

it could be good to have the same simple macro in GTest.

Thanks Emmanuele, moving them into /skipped/ is useful.

from an API standpoint, it might be interesting to have "regions" in the test suite; something like:

  /* creates a "skip" region in the test suite; all the test functions
   * added inside this region will be executed only if @condition
   * evaluates to %TRUE; if it evaluates to %FALSE, the tests will not
   * be executed, and the will be appended under @prefix.
   */
  void
  g_test_push_skip_region (gboolean    condition,
                           const char *prefix);

  /* creates a "todo" region in the test suite; all test functions
   * added inside this region will be expected to fail . if they do
   * not fail, they will be appended under @prefix. in both cases,
   * they will not stop the execution of the test suite.
   */
  void
  g_test_push_todo_region (const char *prefix);

  /* terminates the innermost region */
  void
  g_test_pop_region (void);

I rather we just add g_test_skip().

I would happily accept a patch to add g_test_skip

cool, I'll have a go at it today, then.

I just added g_test_skip and g_test_incomplete
