table-driven-test

Table-driven tests define multiple test cases in a slice of structs, then iterate over them executing the same test logic. This makes it easy to add cases, improves readability, and reduces duplication.

Not the same as: Datadriven tests (different library with testdata files)

Order struct fields with input fields at the top and verification fields at the bottom. Prefix all verification fields with expected so readers can immediately distinguish inputs from outputs.
