Unit TestingΒΆ

Unit testing is performed with py.test that can be installed via

pip install pytest

The tests can be found in pypsa/test/ and can be run from there via

pytest

Or to run individual tests:

pytest test_lpf_against_pypower.py

Power flow is tested against PYPOWER (the Python implementation of MATPOWER) and pandapower.

Warning

Note that PYPOWER 5.0 has a bug in the linear load flow, which was fixed in the github version in January 2016.

Note

Note also that the test results against which everything is tested were generated with the free software LP solver GLPK; other solver may give other results (e.g. Gurobi can give a slightly better result).

Unit testing of new GitHub commits is automated with Github Actions.
