#expects(schema_name, collision: :error, singular: nil, validation: :permissive) ⇒ Object

Define a new expectation schema Options:

collision: :error|:force -> method name collision policy for dynamic definitions
singular: string|symbol  -> control singular name for the schema
validation: :permissive|:strict -> unknown key handling
