**Full Changelog**: https://github.com/codedawi/pytest-schema/compare/v0.1.1...v0.1.2

- Fixes bug related to `Enum` validate report in 1.
- Adding two new methods `like` and `exact` that are mirrors of `like_schema` and `exact_schema`.

A `pytest` based wrapper around the [`keleshev/schema v0.7.3`](https://github.com/keleshev/schema) package to allow uses to easy use this for validating integration test responses or other type/dict based validation. This allows users to quickly write up a pythonic schema and reduces the need for them to hard code matching values.

Packages offers `schema`, `like_schema`, `exact_schema` methods for validating schema using `==` or `!=`.

Updated the `long_description_content_type` to `text/markdown` for pypi.org

Basic implementation of validating return values against a schema-like object in testing.
