+## Testing
+
+You can run tests with `npm test`. The tests use `testing-library`, `pact`,
+and `jest`.
+
+Here's some short guidelines:
+
+- Every component that receives props or changes state should be tested.
+- Test expected outcomes, not implementation details.
+- Avoid mocking unless it's an external call
+- Stores that interact with the API should be tested using pact
