Assess a model using a When decomposition sequence.
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
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,
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');
Simulate the test harness to run the assessments.
Close the test harness and main model.
