96d3f3de - Discover and run C++ tests with run_test.py (#99559)

Discover and run C++ tests with run_test.py (#99559) This depends on [pytest-cpp](https://github.com/pytest-dev/pytest-cpp) to discover and run C++ tests with pytest. C++ tests are built under `${WORKSPACE}/build/bin` directory and copied to the test job under the same path. * To expose them to `run_test`, I choose to use the mock path prefix `cpp`, for example `build/bin/c10_Array_test` would be named as `cpp/c10_Array_test` and the `python test/run_test.py --cpp -i cpp/c10_Array_test` would run the test in the same way as other Python tests. I could copy them from `build/bin` to `test/cpp`, but it will be mixed with the source code and CMake file. So this looks easier * Some executable under `build/bin` are not C++ tests, and they are exclude, for example `build/bin/torch_shm_manager` * C++ tests need to run with pytest directly as python command doesn't understand it * The change is gated by the new `--cpp` argument to `run_test.py`, for example `python test/run_test.py --cpp` will run all available C++ tests * The tests can be run in parallel * Failing tests can be retried with `--reruns=2` and `--sw` ``` ============================= test session starts ============================== platform darwin -- Python 3.9.15, pytest-7.2.0, pluggy-1.0.0 -- /Users/huydo/miniconda3/envs/py3.9/bin/python3 cachedir: .pytest_cache hypothesis profile 'default' -> database=DirectoryBasedExampleDatabase('/Users/huydo/Storage/mine/pytorch/test/.hypothesis/examples') rootdir: /Users/huydo/Storage/mine/pytorch, configfile: pytest.ini plugins: xdoctest-1.1.0, cpp-2.3.0, rerunfailures-10.3, shard-0.1.2, flakefinder-1.1.0, hypothesis-6.56.4, xdist-3.0.2, repeat-0.9.1 collecting ... collected 3 items / 2 deselected / 1 selected Running 1 items in this shard: build/bin/scalar_tensor_test::TestScalarTensor.TestScalarTensorMPS stepwise: skipping 2 already passed items. ../build/bin/scalar_tensor_test::TestScalarTensor::TestScalarTensorMPS RERUN [100%] ../build/bin/scalar_tensor_test::TestScalarTensor::TestScalarTensorMPS RERUN [100%] ../build/bin/scalar_tensor_test::TestScalarTensor::TestScalarTensorMPS FAILED [100%] ``` * `--import-slow-tests` and `--import-disabled-tests` won't work for now and that's ok to have it as a future task. I also add `pytest-cpp==2.3.0` to Linux Docker, MacOS, and Windows. ### Testing Build PyTorch and run `python test/run_test.py --cpp` on my laptop. CI change would come later in a separate PR. Also running `python test/run_test.py --help` now shows all C++ test discovered under `build/bin` Pull Request resolved: https://github.com/pytorch/pytorch/pull/99559 Approved by: https://github.com/clee2000
