Test Models Using MATLAB Unit Test
You can use the MATLAB® Unit Test framework to run tests authored in Simulink® Test™. Using the MATLAB Unit Test framework:
Allows you to execute model tests together with MATLAB Unit Test scripts, functions, and classes.
Enables model and code testing using the same framework.
Enables integration with continuous integration (CI) systems, such as Jenkins®.
To run tests with MATLAB Unit Test:
TestSuitefrom the Simulink Test file.
Create plugin objects to customize the
TestRunner. For example:
matlab.unittest.plugins.TAPPluginproduces a results stream according to the Test Anything Protocol for use with certain CI systems.
sltest.plugins.ModelCoveragePluginspecifies model coverage collection and lets you return coverage results at to the command line. If you set up coverage in the Test Manager, you do not need to use this plugin.
Add the plugins to the
When running tests using MATLAB Unit Test, consider the following:
If you disable a test in the Test Manager, the test is filtered using MATLAB Unit Test, and the result reflects a failed assumption.
Comparison of Test Nomenclature
MATLAB Unit Test has analogous properties to the functionality in Simulink Test. For example,
If the test case contains iterations, the MATLAB Unit Test contains parameterizations.
If the test file or test suite contains callbacks, the MATLAB Unit Test contains one or more callbacks fixtures.
Test Case Iterations and MATLAB Unit Test parameterizations
parameterization details correspond to properties of the iteration.

Test Callbacks and MATLAB Unit Test Fixtures
Fixtures depend on callbacks contained in the test file. Fixtures do not include test case callbacks, which are executed with the test case itself.

Basic Workflow Using MATLAB® Unit Test
This example shows how to create and run a basic MATLAB® Unit Test for a test file created in Simulink® Test™. You create a test suite, run the test, and display the diagnostic report.
Before running this example, temporarily disable warnings that result from verification failures.
warning off Stateflow:Runtime:TestVerificationFailed; warning off Stateflow:cdr:VerifyDangerousComparison;
1. Author a test file in the Test Manager, or start with a preexisting test file. For this example,
AutopilotTestFile tests a component of an autopilot system against several requirements, using
2. Create a
TestSuite from the test file.
apsuite = testsuite('AutopilotTestFile.mldatx');
3. Create the test runner.
import matlab.unittest.TestRunner aprunner = TestRunner.withNoPlugins;
4. Add the plugin to produce Test Manager results.
import sltest.plugins.TestManagerResultsPlugin tmr = TestManagerResultsPlugin; addPlugin(aprunner,tmr)
5. Run the test.
apresults = run(aprunner,apsuite);
6. View the summary of the test, which shows that the test failed because of a verification failure.
ans = TestResultContainer with properties: TestResult: [1x1 sltest.testmanager.TestCaseResult]
