| Integrations | Hspec integrates with QuickCheck, SmallCheck, and HUnit. | The documentation describes loading external plugins, including pytest-cov, and pytest can be invoked from Python code. |
| Purpose | Hspec is a testing framework for Haskell. | pytest is a framework for writing small, readable tests that can scale to complex functional testing for applications and libraries. |
| Test discovery | The `hspec-discover` preprocessor scans for spec files and generates test driver boilerplate. | pytest automatically discovers test modules and functions using standard naming conventions. |
