Commonly assumed
Calling the spaceship operator <=> or relational comparison operators (<, <=, >, >=) on Sets performs a total ordering comparison based on size or element values so arrays of sets can be sorted, and comparison methods accept any Enumerable.
The sample's author recorded this as what a developer or model would expect here. The contract below is what actually ran.
Contract
- assert Set#<=> returns nil when neither set is a subset of the other rather than ordering by size or elements, causing Array#sort across disjoint sets to raise ArgumentError
- assert Set#<=> returns -1, 0, or 1 only when sets have a subset, equality, or superset relationship
- assert relational operators <, <=, >, >= on disjoint sets evaluate to false in both directions rather than establishing an ordering
- assert subset and relational comparison methods raise ArgumentError with 'value must be a set' when passed an Array, while set algebra methods (+, -, &, |, ^) accept any Enumerable
- assert Set#<=> returns nil when comparing a Set with an Array
