This is a plugin to facilitate image comparison for Matplotlib
|
|
figures in pytest. Matplotlib includes a number of test utilities
|
|
and decorators, but these are geared towards the nose testing
|
|
framework. Pytest-mpl makes it easy to compare figures produced by
|
|
tests to reference images when using pytest.
|
|
|
|
For each figure to test, the reference image is subtracted from the
|
|
generated image, and the RMS of the residual is compared to a
|
|
user-specified tolerance. If the residual is too large, the test will
|
|
fail (this is implemented using helper functions from matplotlib.testing).
