Overview

Checks for usage of include_examples.

include_examples, unlike it_behaves_like, does not create its own context. As such, using subject, let, before/after, etc. within shared examples included with include_examples can have unexpected behavior and side effects.

Prefer using it_behaves_like instead.

Examples:

# bad
include_examples 'examples'

# good
it_behaves_like 'examples'
