Verify before relying
pip install pytest-unordered
from pytest_unordered import unordered
assert [1, 20, 300] == unordered([20, 300, 1])What it is and what it does
pytest-unordered is a pytest plugin that adds an `unordered()` wrapper function for assertions that compare collection contents while ignoring element order. It solves the common testing problem where APIs return data structures (lists, tuples, nested objects) in unpredictable or arbitrary order, making naive equality assertions fragile and test code verbose.
The package shines when testing complex nested data structures: you can wrap only the parts where order doesn't matter, leaving other parts under strict order checking. It handles dictionaries, lists, tuples, and generators, and supports both container-type-strict and container-type-agnostic comparison modes. The single runtime dependency is pytest itself, making installation and integration straightforward.
Use it for
- Test REST API responses that return lists of objects in unpredictable order without writing custom comparison logic.
- Assert nested data structures (e.g., customer records with order lists) where only some levels should ignore order.
- Compare collections of dictionaries or other unhashable types where set() or sorted() approaches fail.
- Verify database query results or GraphQL responses that don't guarantee result ordering.
- Write readable, maintainable assertions for complex JSON payloads in integration tests.
