"""Tests build_font.py by renaming a font.

The test copies Roboto-Regular.ttf to a tmp directory and ask build_font.py to rename it and put in another dir.
We then use ttx to dump the new font to its xml and check if rename was successful

To test locally, use:
PYTHONPATH="$PYTHONPATH:/path/to/android/checkout/external/fonttools/Lib" ./test.py
