1.17What not to say
- "I just check the API response to verify data was saved." -- This shows you trust intermediary layers blindly and miss entire categories of bugs.
- "I use SELECT * in all my test queries." -- This signals fragile tests that break on any schema change.
- "I build my SQL queries with string concatenation." -- This reveals ignorance of SQL injection risks and poor engineering habits.
- "I only test the happy path at the database level." -- This misses NULL handling, default values, and data anomaly detection.
