Prepare for running tests of pyAMReX by building pyAMReX from source.

In order to run our tests, you need to have a few Python packages installed:

python3 -m pip install -U pip
python3 -m pip install -U build packaging setuptools wheel pytest
python3 -m pip install -r requirements.txt


You can run all our tests with:

ctest --test-dir build --output-on-failure

Further Options

For faster compile-and-test iterations, build with -DpyAMReX_IPO=OFF:

ctest -S . -B build -DpyAMReX_IPO=OFF

After successful installation, with

ctest --test-dir build --target pip_install

you can also run the unit tests individually. For AMReX_MPI=ON, please prepend the following commands with mpiexec -np <NUM_PROCS>

# Run all tests
python3 -m pytest tests/

# Run tests from a single file
python3 -m pytest tests/test_intvect.py

# Run a single test (useful during debugging)
python3 -m pytest tests/test_intvect.py::test_iv_conversions

# Run all tests, do not capture "print" output and be verbose
python3 -m pytest -s -vvvv tests/
