• The guideline refers to en dashes but shows an em dash; use the correct en dash character (–) instead of an em dash (—) to match the description.

Use **en dashes (—)** to indicate numeric ranges. Do **not** mix styles or use hyphens inconsistently.

• [nitpick] Per sentence-case guidelines, consider using lowercase 'first' ("your first test case") since it's not a proper noun.

**Step-2**: Give a title to your First test case

• Consider checking and handling errors from subsequent DB operations (like Find) to avoid silent failures.

            pSQL_DB = pSQL_DB.WithContext(c.Request.Context())

• The variable x is declared but not used. Consider renaming it to something descriptive or handling the result/error explicitly.

            x := pSQL_DB.Find(&people)
