# Manual testing procedure

- Go through every control in IUP's documentation and compare to Clear Coat's documentation to verify that the methods in Rust are a subset of those in C.
- Go through literals passed to C and make sure they have null terminators so that they don't have to be copied first.
- Go through setters and make sure they return `&Self`.
- Check that pointers are not compared to `std::ptr::null()` or `std::ptr::null_mut()`. Preferably, the `is_null` method would be used instead.
