+// This test file validates that std::vector<T>::reserve provides a strong exception guarantee if T is
+// Cpp17MoveInsertible and no exception is thrown by the move constructor of T during the reserve call.
+// It also checks that if T's move constructor is not noexcept, reserve provides only a basic exception
