This is a test app which verifies that std::filesystem features work in ESP-IDF. The tests are written using Catch2 managed component.
To run the tests:
idf.py flash monitor
Or, in QEMU:
idf.py qemu monitor
Or, using pytest:
idf.py build
pytest --embedded-services idf,qemu --target esp32 --ignore managed_components
Please update _cplusplus_filesystem section in cplusplus.rst when modifying this table.
