//! Rebuilding tests
//! ----------------
//!
//! This tests module ensures that the initial build of the virtualdom is correct.
//! This does not include dynamic tests or the diffing algorithm itself.
//!
//! It does prove that mounting works properly and the correct edit streams are generated.
//!
//! Don't have a good way to validate, everything is done manually ATM
