The Two Postgres Bugs the Tests Caught: A Real-DB Integration Test Case Study
📰 Dev.to · Jeremy Longshore
Learn how a no-mocks testcontainers policy caught two critical Postgres bugs in a real-DB integration test case study and why it matters for reliable database testing
Action Steps
- Implement a no-mocks testcontainers policy for your Postgres database
- Run integration tests using testcontainers to catch production-fatal bugs
- Configure your tests to check for schema USAGE removal and asymmetric SELECT grants
- Test your database schema and grants to ensure they are correctly configured
- Analyze test results to identify and fix potential bugs before they reach production
