よくある思い込み

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.

このサンプルの作者が、ここで開発者やモデルが期待するであろうこととして記録したもの。下の契約が実際に実行されたものだ。

コントラクト

• 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
