As noted earlier, tests
have been written to verify the operation of certain specific areas of
interest in the C++ library support, particularly the use of exceptions
from multiple threads which is addressed in the throw* tests.
The GNU libstdc++ v3 testsuite has been imported into this package
and may be found under the tscpp
subdirectory of this package. There are a large number of tests
within the libstdc++ testsuite of varying rigour. An analysis of the
coverage has been made, and any notable gaps in the test
coverage have been addressed in the custom tests in the
tests subdirectory of this package.
The testsuite is quite large and takes some time to build, and so
although built by default it may disabled with the
CYGPKG_LIBSTDCXX_OFFICIAL_TESTSUITE CDL option.
Some tests contain aspects which only operate if the RAM filesystem
package is enabled, therefore to test the library more thoroughly
developers may wish to consider enabling the RAM filesystem.
Notes on how the libstdc++ testsuite was imported, including what
types of changes were made and what the results were, are available
within this package in the tscpp/NOTES text file.
