/*
  Unit tests for the profile wallet address selector.

  The profile page must show follow/mute controls only when the viewer's
  wallet address is known. The React app tracks the loaded address both in the
  wallet object and in `bchWalletState`; the selector prefers the reactive
  state so the profile reloads when the address becomes available.
