Write a C++ test

We strongly recommend each developer to write C++ unit tests when sending a PR.

• We use googletest as the C++ test infrastructure.
• C++ tests should be added to the tests/cpp/ directory.
• Make sure your C++ test source file is covered by this CMake glob.

Build and run Taichi C++ tests

# build taichi with tests enabled
TAICHI_CMAKE_ARGS="-DTI_BUILD_TESTS:BOOL=ON" python setup.py develop

# run the C++ test
TI_LIB_DIR=$TAICHI_INSTALL_DIR/_lib/runtime ./taichi_cpp_tests

note

$TAICHI_INSTALL_DIR can be retrieved from taichi.__path__[0] in python.

note

On Windows, taichi_cpp_tests.exe will be placed inside the %TAICHI_REPO_DIR%\bin directory.

note

Consider polishing the C++ test infrastructure:

• Separate each translation unit into its own test executable
• Have a unified script to control the execution of which set of tests
