Create minimal test runner with no plugins

Syntax

Description

runner = matlab.unittest.TestRunner.withNoPlugins creates a minimal, silent test runner with no plugins installed, and returns it as amatlab.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.

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);
