# Tests for C++ interoperability
|
|
|
|
Each D file will be compiled and linked with other C++ sources defined in a
|
|
[`EXTRA_CPP_SOURCES` parameter](../README.md#test-configuration).
|
|
Any diagnostic emitted must match the predefined diagnostic in the test
|
|
file, otherwise the test will fail.
|
|
|
|
All compiled executables will be run and are expected to finish successfully
|
|
with exit code 0. Any output from those binaries must be defined via the
|
|
[`RUN_OUTPUT` parameter](../README.md#test-configuration).
|
|
|
|
## Purpose
|
|
|
|
The point of these files is to test that the compiler emits valid code
|
|
which can interface to binaries generated by a C++ compilers.
|
|
|
|
## Remarks
|
|
|
|
All test will be run for a variety of C++ compilers and targets, refer to the
|
|
[GitHub CI configuration](../../.github/workflows/runnable_cxx.yml) for more details.
|
|
|
|
The [remarks for runnable tests](../runnable/README.md#remarks) apply to
|
|
this category.
|
|
|
|
Refer to [test/README.md](../README.md) for general information and the
|
|
[test guidelines](../README.md#test-coding-practices).
