MATLAB Programming Fundamentals - MathWorks

After the framework completes evaluating the superclass method, the runTestSuite

method displays the assertion count summary.

Extend Creation of Shared Test Fixtures and TestCase Instances

Add listeners to AssertionPassed and AssertionFailed events to count the

assertions. To add these listeners, extend the methods that the test framework uses to

create the test content. The test content comprises TestCase instances for each Test

element, class-level TestCase instances for the TestClassSetup and

TestClassTeardown methods, and Fixture instances that are used when a TestCase

class has the SharedTestFixtures attribute.

Invoke the corresponding superclass method when you override the creation methods.

The creation methods return the content that the test framework creates for each of their

respective contexts. When implementing one of these methods, pass this argument out of

your own implementation, and add the listeners required by this plugin.

Add these creation methods to a methods block with protected access.

methods (Access = protected)

function fixture = createSharedTestFixture(plugin, pluginData)

fixture = createSharedTestFixture@...

matlab.unittest.plugins.TestRunnerPlugin(plugin, pluginData);

fixture.addlistener('AssertionPassed', ...

@(~,~)plugin.incrementPassingAssertionsCount);

fixture.addlistener('AssertionFailed', ...

@(~,~)plugin.incrementFailingAssertionsCount);

end

function testCase = createTestClassInstance(plugin, pluginData)

testCase = createTestClassInstance@...

matlab.unittest.plugins.TestRunnerPlugin(plugin, pluginData);

testCase.addlistener('AssertionPassed', ...

@(~,~)plugin.incrementPassingAssertionsCount);

testCase.addlistener('AssertionFailed', ...

@(~,~)plugin.incrementFailingAssertionsCount);

end

function testCase = createTestMethodInstance(plugin, pluginData)

testCase = createTestMethodInstance@...

matlab.unittest.plugins.TestRunnerPlugin(plugin, pluginData);
