# Code Required

```cpp

    auto const contains_test = requires(T t)

    {

        { t.Test(1, 2) } -> std::same_as;

    };

```

# In C++17

```cpp

    static constexpr auto const contains_test = static_cast(boost::hana::is_valid(

        [](auto &&obj) -> decltype(obj.Test(1, 2)) {

        })(t));

```
