The article introduces a generic MustCreate helper pattern in Go tests that eliminates repetitive error-checking boilerplate when constructing known-valid values. By leveraging Go 1.18 generics, it replaces multiple MustCreateFoo, MustCreateBar helpers with a single reusable MustCreate[T] function.
Background
Go 1.18 introduced generics support, enabling type-parameterized functions and methods. Testing utilities that previously required per-type wrappers can now be unified into generic helpers.
