%% Using When Decomposition to Write Tests % % Assess a model using a When decomposition sequence. % Copyright 2015 The MathWorks, Inc. %% % This example shows how to use When decomposition in a Test Sequence % block to author assessments in a test harness. The example model % implements a simple signal tracker that operates in three modes: % off (0), slow (1) and quick (2). Simulate the model and observe the % output and error of the signal tracker. % mdl = 'sltestTestSequenceWhenExample'; open_system(mdl); open_system([mdl '/Scope']); sim(mdl); %% % Open the test harness attached to the |SimpleTracker| subsystem, and % open the Test Sequence block named |Test Assessment| that assesses % the behavior of |SimpleTracker|. % % The Test Sequence block uses When decomposition to determine the % appropriate assertions to run depending on the |SimpleTracker| mode. % The |CheckError| step is a When decomposition step, and it has three % substeps, |OffMode|, |SlowMode|, and |QuickMode| that are active when % mode is *0*, *1* or *otherwise*, respectively. open_system(mdl); sltest.harness.open([mdl '/SimpleTracker'],'SimpleTrackerHarness'); open_system('SimpleTrackerHarness/Test Assessment'); %% % % <<sltestTestSequenceUsingWhenAssessment.png>> %% % Simulate the test harness to run the assessments. open_system('SimpleTrackerHarness/Scope'); sim('SimpleTrackerHarness'); %% % Close the test harness and main model. close_system(mdl, 0); %% clear mdl; displayEndOfDemoMessage(mfilename)
