Pattern: Missing use of predicate matcher
Issue: -
Prefer using predicate matcher over using predicate method directly.
RSpec defines magic matchers for predicate methods. This rule recommends to use the predicate matcher instead of using predicate method directly.
# bad
expect(foo.something?).to be_truthy
# good
expect(foo).to be_something
# also good - It checks "true" strictly.
