EarthPy

A package that supports working with spatial data in python teaching.

Install

To install, use pip. --upgrade is optional but it ensures that the package overwrites when you install and you have the current version. If you don't have the package yet you can still use the --upgrade argument.

$ pip install --upgrade git+https://github.com/earthlab/earthpy.git

Then import it into python.

>>> import earthpy as et

Testing

This package uses pytest for tests. To run tests locally, execute the command pytest from the command line:

$ pytest --doctest-modules

The --doctest-modules syntax allows pytest to check examples in docstrings contained in modules (e.g., if a function has an example section), in addition to the normal tests that pytest would discover.

Testing example code in the docs directory

To locally test examples in the docs directory (e.g., examples contained in .rst files), you can run the following command from the top-level earthpy directory:

$ make -C docs doctest

Data generated for testing

If a test requires a data object such as a GeoDataFrame or numpy array, and copies of that data object are required by multiple tests, we can use pytest fixtures to cleanly create and tear down those objects independently for each test.

See earthpy/tests/conftest.py for fixture definitions, and earthpy/tests/test_clip.py for example usage of fixtures in tests.
