研究方向

Investigate the implementation of `toInclude` in the expect library (likely in the main source file). Currently, it only handles plain objects; you need to add support for Map objects by checking if the actual value is a Map and then iterating over its entries to match the expected properties. Review existing tests for `toInclude` to understand the testing patterns and ensure the fix doesn't break existing functionality.
