The Nengo team at ABR is excited to announce the first release of
pytest-plt is made available under the open source MIT license so that all Python projects can make use of it to better test their numerical code.
What is pytest-plt?
pytest-plt makes plotting in your tests easy by providing a
plt fixture for pytest.
Create PDF plots in one line with the
import numpy as np def test_rectification(plt): values = list(range(-10, 11)) rectified = [v if v > 0 else 0 for v in values] assert all(v >= 0 for v in rectified) plt.plot(values, label="Original") plt.plot(rectified, label="Rectified") plt.legend()
To generate the plot, pass
If you don’t pass
--plots, calls to
plt function will be ignored, meaning that your tests won’t spend time making plots that won’t get saved.
Where can I learn more?
pytest-plt gives you several ways to customize the directory that your plots end up in, and the filenames of all the plots in that directory. For the full details, see the documentation.
