Improve utilities sending channels, pixels and other GIL objects to
output stream for logging of test errors.
Fix missing namespace qualification in IO tests.
Comment TARGA test case with FIXME that was accidentally
uncommented in cc64bdd1a4
Split header tests accordingly i.e. test core headers as part of
core tests, numeric extension headers as part of numeric tests, etc.
It extends the convention of sub-directories already established in
`include/boost/gil` directory. It is sensible to follow it in other
areas of the source tree (i.e. `test/`, `doc/` and `benchmark/`).
Another important reason to move the tests is to enable removal of
the top-level `Jamfile` with all its definitions of test-specific
requirements.
The top-level `Jamfile` is not advised, especially if it specifies
build requirements like C++ language version.
Those affect non-tests builds e.g. documentation, causing failures
during generation of HTML documentation (leads to missing docs).
Document maintenance rules of `test/legacy/` content.
Motivation to move the `test/legacy/` is to:
* clarify status of those tests
* make it easier to run tests selectively
* separate new/upcoming feature-specific tests
from those all-in-one tests.
Other changes:
Rename `gil_test_common.hpp` to `unit_test.hpp` to make
it clearer it acts as `boost/test/unit_test.hpp proxy`.
Remove `<include>$(BOOST_ROOT)` from `Jamfile`-s as unnecessary.
when building tests with both, Boost.Build and CMake.
Disable concepts check for tests where range (e.g. std::array)
used as image pixel - not fully specialised as acceptable pixel type.
Ignore warnings from boost/concept_check.hpp
Rationalise uses of GCC and clang diagnostic push/pop,
with adding constraint for GCC 4.6+ as minimum version
where the pragma was introduced.
Closes#228
Replace global compile options and definitions with interface targets.
Remove globing for headers.
Set project version based on GIL version.
Remove GIL_BUILD_TESTS option as redundant - there is no point in
using CMake for development of header-only library if no tests
are to be built.
Add GIL_DISABLE_FINDBOOST_DOWNLAOD option (default=OFF).
Output values of Boost_INCLUDE_DIRS and BOOST_LIBRARY_DIRS
- should help to know which Boost we are building GIL against.
Fix add_executable with empty sources list.
Copied from Boost.Geometry, including original tests, with some non-functional
modifications explained in the comments.
The utility can be used where it is important to avoid integer overflow.
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.
First stab at collection of CMakeLists.txt for Boost.GIL
- Allow building and testing boostorg/gil against Boost from
cloned superproject or installed distribution.
Add CMakeSettings.json config file for VS2017 integration with CMake
- Defines build configurations for VS and Ninja generators.
- Can be used as is or as a template ready to customise.
Add conanfile.txt for Conan package manager (eg. for cmake -DGIL_USE_CONAN=ON).
Add .editignore file to with basic encoding of CMake and CI scripts.
Update .appveyor.yml with two extra CMake-based builds (allowed to fail).
