We need tests in the repository

[rlepigre]

A first step could be to use this test suite, which is what I originally did (and it is used here).

[Ravenslofty]

I'd actually use the AFL synthesized tests from here, which was what I used as a base point.

[rlepigre]

But do you have coverage guarantees with such tests?

Anyway, it may be a good idea to do both!

[Ravenslofty]

Both is certainly an option. Since AFL works by trying to maximise coverage, it's at least a reasonably thorough test.

👍 for a set of files (regression testing) and using AFL to produce new ways to trip the parsers (that can then be added to the regression testing set)
