# End-to-end test for C++ bindings
#
# This provide the final test in D's C++ compatibility,
# an end-to-end test using standard C++ library.
# Testing C++ interop is done in two stages: at the lower layer,
# compilers will test C++ features in isolation (or combination,
# as can be seen in `dmd/compiler/test/runnable_cxx/` for example.
# The second layer, this one, test C++ interop assuming the compiler
# generates the proper mangling / uses the right ABI.
name: E2E tests
# Only triggers on pushes to master & stable, as well as PR to master and stable
# Sometimes reverts appear in the upstream repository (e.g. when the revert button
# is clicked by a contributor with commit access), this should be tested as PR).
#
# Also note that Github actions does not retrigger on target branch changes,
# hence the check on push.
