  /// @brief Generic test observer interface
  ///
  /// This interface is used by observers in order to receive notifications from the
  /// Boost.Test framework on the current execution state.
  ///
  /// Several observers can be running at the same time, and it is not unusual to
  /// have interactions among them. The @ref test_observer::priority member function allows the specification
  /// of a particular order among them (lowest priority executed first, except specified otherwise).
