How to contribute
We welcome contributions!
You can help by:
Suggesting new features
Adding features to the codebase
Expanding the testing suit
Improving the documentation
How to Report Issues
When reporting issues, please include as many of the the following details as possible:
Which version of Kadlu you are using
The source code that generated the problem (if applicable)
Which platform you are using (Operating system and version)
A minimum example that reproduces the issue
What result you got
What you were expecting
We use GitLab as a repository, so the best way to submit issues is through the issues system.
We welcome merge requests and additional features to the repository.
The preferred style guide for new contributions is PEP 8.
When creating a request, please include a single feature per merge, on a branch forked from master.
For small updates, a description of the changes in the merge request is sufficient.
For larger contributions please open a discussion thread in the issue tracker before merging.
Please include tests for new features in the
kadlu/tests directory - if a test generates or downloads new data, include cleanup code here as well.
Finally, please run the tests before merging and ensure tests complete locally before submitting a merge request.
Thank you for your contributions!
Running the tests
Kadlu includes its own test suite. They are included in the /kadlu/tests/ directory.
To run all tests, run:
pytest --doctest-modules kadlu
You can also specify a module:
File testing with the python debugger (PDB)
start a debugging session for reading .nc and .tif file formats.
dynamically generates tests for a given set of input data files. pytest tests will be written to a script using files in
kadlu_data/testfiles/as inputs. this is then run in a pytest subprocess, the test script will be cleaned upon exit.
pytest config can be passed using the
DEBUGOPTSenvironment variable: by default the script will drop into an interactive pdb debugging session. to set a breakpoint, add
breakpoint()directly to the source code. otherwise, pdb will break on exceptions.
alternatively, run tests in parallel using the pytest-parallel package
from importlib import reload import os, kadlu # place some files in the testfiles directory kadlu.ifremer().fetch_ifremer_netcdf_hs2013() # reload kadlu and run tests reload(kadlu); kadlu.test_files() # optionally pass args to pytest with DEBUGOPTS os.environ.setdefault('DEBUGOPTS', '--pdb') # default behaviour reload(kadlu); kadlu.test_files()
From the terminal:
# set pytest options export DEBUGOPTS='--pdb --tb=short -s' python3 test_files.py # run tests in parallel and log the results pip install pytest-parallel export DEBUGOPTS='--workers=auto --tb=line --durations=0' python3 -B test_files.py | tee testresults.log
DEBUGOPTSenv var and ‘man pytest’ for further usage information
