When I run the test suite without WebP installed, it fails.
The backstory of this is that #8213 deprecated
features.check("transp_webp")
,features.check("webp_mux")
andfeatures.check("webp_anim")
.However, the deprecation warning is only raised if the underlying WebP module is installed, and the missing module doesn't raise an error earlier than the warning.
Pillow/src/PIL/features.py
Lines 149 to 159 in e93dcc1
This PR updates features.py so that the feature checks raise a deprecation warning when WebP is not installed as well.
