In principle we are still able to explicitly check emptiness here, e.g., we can
replace
ASSERT_EQ(0u, getState.get_tasks().tasks_size());
with
ASSERT_TRUE(getState.get_tasks().tasks().empty());
There is some trade-off between local and global consistency in most of the
cases in e.g., `api_tests.cpp`. When checking proto fields there, we often mix
checking emptiness and checks for a particular size. I would go with a checks
capturing our intention as much as possible, i.e., prefer checking for
emptiness over local typographic consistency.
