Create ExampleTest.m containing the following test class.

classdef ExampleTest < matlab.unittest.TestCase
    methods(Test)
        function testOne(testCase)  % Test fails
            testCase.verifyEqual(5,4,'Testing 5==4')
        end
        function testTwo(testCase)  % Test passes
            testCase.verifyEqual(5,5,'Testing 5==5')
        end
        function testThree(testCase) % Test fails
            testCase.assumeTrue(false)
        end
    end
end

Create a test suite from the ExampleTest class. Create a silent test runner.

import matlab.unittest.TestRunner
import matlab.unittest.TestSuite
import matlab.unittest.plugins.XMLPlugin

suite = TestSuite.fromClass(?ExampleTest);
runner = TestRunner.withNoPlugins;

Create an XMLPlugin that writes test results to the file myTestResults.xml.

xmlFile = 'myTestResults.xml';
p = XMLPlugin.producingJUnitFormat(xmlFile);

Add the plugin to the test runner and run the suite.

runner.addPlugin(p)
results = runner.run(suite);
table(results)
ans = 

             Name              Passed    Failed    Incomplete    Duration       Details   
    _______________________    ______    ______    __________    _________    ____________

    'ExampleTest/testTwo'      true      false     false         0.0038761    [1x1 struct]
    'ExampleTest/testThree'    false     false     true           0.049763    [1x1 struct]

View the contents in the file created by the plugin.

Tips

  • If your test file is a script-based or function-based test, the value of the classname attribute of the <testcase> element is the test file name.
