Testing pysteps#
The pysteps distribution includes a small test suite for some of the modules. To run the tests the pytest package is needed. To install it, in a terminal run:
pip install pytest
Automatic testing#
The simplest way to run the pysteps’ test suite is using tox and the tox-conda plugin (conda needed). To install these packages activate your conda development environment and run:
conda install -c conda-forge tox tox-conda
Then, to run the tests, from the repo’s root run:
tox # Run pytests
tox -e install # Test package installation
tox -e black # Test for black formatting warnings
Manual testing#
Example data#
The build-in tests require the pysteps example data installed. See the installation instructions in the Installing the example data section.
Test an installed package#
After the package is installed, you can launch the test suite from any directory by running:
pytest --pyargs pysteps
Test from sources#
Before testing the package directly from the sources, we need to build the extensions in-place. To do that, from the root pysteps folder run:
python setup.py build_ext -i
Now, the package sources can be tested in-place using the pytest command on the root of the pysteps source directory. E.g.:
pytest -v --tb=line
