Last time it was fixed to a specific version because the `conan`
and the `conan-package-tools` package that `pip install` would
gather were not compatible, let's hope it won't happen again.
* Fix non-default-constructible type lists used in TEMPLATE_LIST_TEST_CASE
std::tuple is not default constructible when the first type is not
default-constuctible. Therefore it can not be instantiated.
to circumvent this, we have to use std::declval in the unevaluate decltype
context.
For some time now (I'd guess almost a year 🤷), the coverage
merging on Windows has been failing, because the reports have been
generated in a different folder than expected. Our merge script did
not report failure because it was not checking the returned error
code from OpenCppCoverage, and for some reason, the `codecov` tool
happily returned 0 even though it did not find the file it was
supposed to upload...
The former is also fixed by this commit.
Parsing --list-tests is broken, as Catch automatically line wraps the
line when it gets too long, stripping any whitespace in the process.
This means that it's impossible to reproduce the exact name of the
test if the test's name is long enough to line-wrap.
Furthermore, overwriting the LABELS property with the discovered labels
breaks users who manually added custom ctest labels.
Rolling back to using --list-test-names-only for now, as it does not
wrap lines even on very long test names.
We may be able parse the output of --list-tags to produce the ctest labels.
However, the straightforward way of doing this is to use CMake's
get_property(TEST ...) and set_property(TEST ... APPEND ...), which don't
work if the test name has spaces or other special characters. We would
need to mangle the test name to a valid CMake identifier to do it that way.
- The current setup tries to detect USE_CPP14/USE_CPP17 and sets the
CXX_STANDARD property for the SelfTest target. This is not ideal, since
CMAKE_CXX_STANDARD can be provided by the toolchain file or as command line
option and should be used by the library internally correctly. Hence, the
whole set of the relevant lines from `projects/CMakeLists.txt` have been
removed.
- The above can also cause subtle issues where the user is expecting the tests
to compile with C++17 after setting CMAKE_CXX_STANDARD and then getting
results of compilation with C++11 as USE_CPP17 has not been set.
- The current build matrix used the above code to run the tests. So, even
though the it should not required anymore to build Catch2, it was still
required to send correct options to build matrix. In that respect,
.travis.yml has been modified to send correct options to the build command
in the new setup.
