generate_test_macro 0.1.2

// Test 2 – generic test suite (mirrors the README example directly)
//
// Uses a generic type parameter `T: MyTrait`, just like `TestSuite<T>` in the
// README.  Verifies that the generated macro correctly threads the concrete
// type through.

// Using `name()` via the trait is tested indirectly; keep the method but
// suppress the dead-code lint so that the API mirrors the README.
