Based on your responses, it looks like you want to save a snapshot of the Site Viewer window, similar to saving a figure window's contents. Unfortunately, Site Viewer doesn't currently have any functionality similar to "savefig" or "saveas" for figures. For now you'd have to use utilities like "print screen" to save an snapshot of the Site Viewer.

You also mentioned wanting to change the size and orientation of the Site Viewer via script. Unfortunately, the orientation currently cannot be set using a script. You can still set the size of the viewer by changing the last two values of the "Position" field of the viewer like so.

viewer = siteviewer;
width = 600; % screen pixels

height = 400; % screen pixels
viewer.Position(3:4) = [width height]

MATLAB: How to assign the Test Diagnostic provided by the Unit Testing framework in the Command Window to a variable

Hi Malek,

You can get programmatic access to this information by creating and installing a TestRunnerPlugin for the test run. This plugin can then listen to qualification failed events (like verification failures, assertion failure, etc) and this diagnostic information is contained in the TestDiagnosticResult property of the event data as a cell array of strings.

Here is a quick example that save all of the test diagnostics for failing verifications in test methods. Note this could expand to cover other cases like assertions, assumptions, etc and other scopes like TestClassSetup, but this might help get you started.

classdef TestDiagnosticSaverPlugin < matlab.unittest.plugins.TestRunnerPlugin
      properties
          TestDiagnosticData
      end
      methods (Access = protected)
          function runTestSuite(plugin, pluginData) 
              plugin.TestDiagnosticData = []; % Reinitialize for each test run
              runTestSuite@...
                  matlab.unittest.plugins.TestRunnerPlugin(plugin, pluginData);
          end
          function testCase = createTestMethodInstance(plugin, pluginData)
              testCase = createTestMethodInstance@...
                  matlab.unittest.plugins.TestRunnerPlugin(plugin, pluginData);
              testName = pluginData.Name;
              testCase.addlistener('VerificationFailed', ...
                @(~,event)plugin.storeTestDiagnosticsData(event,pluginData.Name));
          end
      end
      methods (Access = private)
          function storeTestDiagnosticsData(plugin,eventData,name,failureType)
              s.Name = {name};
              s.TestDiagnostics = eventData.TestDiagnosticResult;
              plugin.TestDiagnosticData = [plugin.TestDiagnosticData; struct2table(s)];
          end
      end
  end

With the above plugin you could then install it on a runner:

>> import matlab.unittest.TestRunner;
>> import matlab.unittest.TestSuite;
>> suite = TestSuite.fromFile('mbd_ZaehlerUnitTest.m')
>> runner = TestRunner.withTextOutput;
>> plugin = TestDiagnosticSaverPlugin;
>> runner.addPlugin(plugin);
>> runner.run(suite)
>> plugin.TestDiagnosticData

Hope that helps! Here are a few links you might find interesting to help you do this:

MATLAB: How to save a web url as an image with specific size

You will probably need to fetch the images and imresize() them.

Sometimes web sites allow you to pass parameters that specify the size of the output file you want, but there is no standard for that and it is common that you can only specify one of the sizes the site has pre-arranged.
