Class: matlab.unittest.TestRunner
Package: matlab.unittest

Create TestRunner object for command window output


runner = matlab.unittest.TestRunner.withTextOutput
runner = matlab.unittest.TestRunner.withTextOutput('Verbosity',v)


runner = matlab.unittest.TestRunner.withTextOutput creates a TestRunner object that is configured for running tests from the MATLAB® Command Window and returns it in runner. The output produced includes test progress as well as diagnostics in the event of test failures.

runner = matlab.unittest.TestRunner.withTextOutput('Verbosity',v) reacts to messages logged at or below the specified verbosity level and controls the level of detail about the test run that is displayed in the Command Window.

Input Arguments

Verbosity levels supported by the test runner, specified as an integer value between 1 and 4 or a matlab.unittest.Verbosity enumeration object. The runner reacts to diagnostics that are logged at this level and lower. Integer values correspond to the members of the matlab.unittest.Verbosity enumeration.

Add matlab.unittest classes to the current import list.

import matlab.unittest.TestRunner;
import matlab.unittest.TestSuite;

Create a TestSuite array.

suite = TestSuite.fromClass(?mypackage.MyTestClass);

Create a TestRunner object that produced output to the Command Window.

runner = TestRunner.withTextOutput;

% Run the suite
result = run(runner,suite)

Create the follow class In a file in your current working folder, ExampleLogTest.m.

classdef ExampleLogTest < matlab.unittest.TestCase
        function testOne(testCase)
            log(testCase,matlab.unittest.Verbosity.Detailed,'Starting Test')
            log(testCase,'Testing 5==5')
            log(testCase,matlab.unittest.Verbosity.Verbose,'Test Complete')

At the command prompt, run the test.

result = run(ExampleLogTest);
Running ExampleLogTest
Done ExampleLogTest
