Add some properties for the Enum module #175

Closed sabiwara closed 2 years ago

sabiwara commented 2 years ago

This PR is adding some property-based tests for some of the Enum functions that had some bugs.

Since the implementation is often duplicated for lists, ranges and reduce-based enums like stream, a nice thing to test is that a function works the same on:

a range
a list made from this range
a stream made from this range

This can catch inconsistencies and bugs, and we can easily add more coverage.
