Mock External APIs for Fast, Reliable Tests
Problem:
Testing with real APIs and databases is slow, expensive, and unreliable.
External dependencies create flaky tests that can fail due to network issues, rate limits, or service downtime rather than code problems.
Solution:
The patch decorator replaces external calls with controllable mock objects for isolated testing.
Key benefits:
- Reproducible results across different machines
- Fast, reliable tests that focus on your logic
- Test edge cases and error conditions that are hard to trigger naturally
Test your data processing logic without waiting for external services or consuming API quotas.
