VerboseTestRunDisplay
classdef VerboseTestRunDisplay < TestRunDisplay
%VerboseTestRunDisplay Print test suite execution results.
%   VerboseTestRunDisplay is a subclass of
%   TestRunDisplay.  It supports the -verbose option of runtests.
%
%   Overriddent methods:
%       testComponentStarted  - Update Command Window display
%       testComponentFinished - Update Command Window display
%       testRunFinished       - Update Command Window display at end of run
