Prompt Evaluation & Testing: Complete Guide for Prompt Engineers
Build systematic test suites to measure prompt quality, catch regressions, and compare prompt versions objectively. Learn when to use it, see a real example, and understand the best practices.
When to Use This Technique
Before deploying any prompt to production. Also essential when updating prompts that are already live.
Example Prompt
Maintain a test dataset of 50+ input/expected-output pairs. Run each prompt version against the dataset and track pass rate.
Pro Tips
- ✓Separate evals for different failure modes
- ✓Use LLM-as-judge for qualitative criteria
- ✓Track regression, new prompts can break old cases
- ✓Include adversarial and edge case inputs in your eval set
