Create minimal test runner with no plugins

Syntax

runner = matlab.unittest.TestRunner.withNoPlugins

Description

runner = matlab.unittest.TestRunner.withNoPlugins creates a minimal, silent test runner with no plugins installed, and returns it as a matlab.unittest.TestRunner object. The returned test runner is the simplest runner possible and produces no text output.

Use this method to create a test runner when you want to have complete control over which plugins are added to the runner.

Customize Runner to Generate Test Artifact

Generate JUnit-style test results by creating a minimal runner and then adding an XMLPlugin instance to the runner.

In a file named eyeTest.m in your current folder, create a function-based test to test the eye function.

function tests = eyeTest
tests = functiontests(localfunctions);
end

function doubleClassTest(testCase)
actual = eye;
verifyClass(testCase,actual,"double")
end

function singleClassTest(testCase)
actual = eye("single");
verifyClass(testCase,actual,"single")
end

function uint16ClassTest(testCase)
actual = eye("uint16");
verifyClass(testCase,actual,"uint16")
end

function sizeTest(testCase)
expected = [7 13];
actual = eye(expected);
verifySize(testCase,actual,expected)
end

function valueTest(testCase)
actual = eye(42);
verifyEqual(testCase,unique(diag(actual)),1)    % Diagonal values must be 1
verifyEqual(testCase,unique(triu(actual,1)),0)  % Upper triangular values must be 0
verifyEqual(testCase,unique(tril(actual,-1)),0) % Lower triangular values must be 0
end

To run the tests, first import the classes used in this example.

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

Create a test suite from the tests in eyeTest.m.

suite = testsuite("eyeTest.m");

Create a test runner with no plugins. This code creates a silent runner that produces no output.

runner = matlab.unittest.TestRunner.withNoPlugins;

You can now add any plugins you choose. Create a plugin that writes JUnit-style XML output to the file myTestResults.xml in your current folder. Then, add the plugin to the test runner.

xmlFile = "myTestResults.xml";
p = XMLPlugin.producingJUnitFormat(xmlFile);
addPlugin(runner,p)

Run the tests. In this example, all the tests pass.

results = run(runner,suite);
