Motivation: - state clearly what is covered with tests without reading non-trivial code - avoid cleverness - tests should be no-brainer - get closer to one test case targets one feature/beaviour with one check - replace obscure `throw std::exception` with diagnostics that are actually useful to pin-point failure cause and location - makes CI logs useful. - allow to select and run specific tests - make tests maintenance easy, quick and fun Propose new structure of tests that reflects the previous tests hierarchy, but organizes channel tests in test/channel directory with test programs each covering specific library feature (or set of closely related features). The refactored tests cover 100% of checks from the old `channel.cpp`, plus it refines or adds a bunch more. NOTE: old test/channel.cpp has not been removed yet. Common definitions from the single test/channel.cpp moved to channel_test_fixtures.hpp and namespace boost::gil::test::fixture: Classes and typedefs: - `do_test` as `fixture::channel` - `value_core` as `fixture::channel_value` - `reference_core` as `fixture::channel_reference` - `packed_reference_core` as `fixture::packed_channel_reference` - `packed_dynamic_reference_core` as `fixture::packed_dynamic_channel_reference` - `channel_archetype` and relatives to `channel_concepts.cpp` which is compile test in Jamfile - `test_packed_channel_reference()` parts as `fixture::packed_channels565` - `test_packed_dynamic_channel_reference()` parts as `fixture::packed_dynamic_channels565` Test case functions called from `do_test<T>::test_all`: - `test_channel_invert()` to `algorithm_channel_invert.cpp` suite - `test_channel_convert()` to `algorithm_channel_convert.cpp` suite - `test_channel_multiply()` to `algorithm_channel_multiply.cpp` suite - `test_channel_math()` split to `algorithm_channel_relation.cpp` and `algorithm_channel_arithmetic.cpp` Add test cases for each channel value type T as used to run from `test_channel_value_impl<T>`, `test_packed_channel_reference<T>` and `test_packed_dynamic_channel_reference<T>`. Add list of possible T-s defined as type-lists `fixture::channel_byte_types`, `fixture::channel_integer_types`, `channel_float_types` and `channel_bitfield_types` which used with `BOOST_AUTO_TEST_CASE_TEMPLATE` generate all possible combination of inputs. Add new `channel_test_fixture.cpp` is a self-test suite verifying the fixtures.
