## Runner Exceptions
The automated tests through Github work for the most part however there are a few exceptions that have to be accounted for due to limitations of the VMs and the graphics emulation used.
These exceptions are either skipped, or handled by using a 1px or 1/255rgba tolerance - when run locally on real hardware, these tests pass fine at the default 0 tolerance.
| Test | OS | Exception | Reason |
| -------------------------- | --------- | ------------------- | ------ |
| love.graphics.points | MacOS | 1px tolerance | Points are offset by 1,1 when drawn |
| love.graphics.setWireframe | MacOS | 1px tolerance | Wireframes are offset by 1,1 when drawn |
| love.graphica.arc | MacOS | Skipped | Arc curves are drawn slightly off at really low scale |
| love.graphics.setLineStyle | Linux | 1rgba tolerance | Rough lines blend differently with the background rgba |
| love.audio.RecordingDevice | All | Skipped | Recording devices can't be emulated on runners |
---
## Future
- [ ] add BMfont alts for font class tests (Rasterizer + GlyphData)
- [ ] graphics.isCompressed() should have an example of all compressed files
