matlab.unittest.plugins.TestReportPlugin class

Package: matlab.unittest.plugins

Plugin that produces a test result report

Description

TestReportPlugin creates a plugin that directs the TestRunner to produce a test result report. Using this plugin, you can produce readable and archivable test reports.

Construction

Instantiate a TestReportPlugin using one of its static methods:

  • To produce a .docx report, use the producingDOCX static method.

  • To produce a PDF report, use the producingPDF static method.

Properties

expand all

This property is read-only.

Indicator if text output from Command Window is included, specified as false or true (logical 0 or 1). By default, IncludeCommandWindowText is false and the text output from the Command Window is excluded from the report. To include Command Window text in the report, specify IncludeCommandWindowText as true during plugin construction.

This property is read-only.

Indicator if diagnostics for passing events are included, specified as false or true (logical 0 or 1). By default, IncludePassingDiagnostics is false and the diagnostics from passing events are excluded from the output. To include diagnostics from passing events in the output, specify IncludePassingDiagnostics as true during plugin construction.

This property is read-only.

Maximum verbosity level for logged diagnostics included by the plugin, returned as a matlab.unittest.Verbosity enumeration object. The plugin includes diagnostics that are logged at this level and below. By default this property value is matlab.unittest.Verbosity.Terse. You can specify a different logging level during plugin construction.

Logged diagnostics are diagnostics that you supply to the testing framework with a call to the TestCase.log or Fixture.log method.

Methods

producingDOCXConstructs plugin that produces .docx report
producingHTMLConstructs plugin that produces .html report
producingPDFConstructs plugin that produces .pdf report

Create a test suite from two test files, run the suite, and generate a .docx report of the results.

Create a new file in your working folder named ScriptBasedTest.m containing the following test script. The script includes two failing and incomplete tests.

%% Test double class
expSolution = 'double';
actSolution = ones;
assert(isa(actSolution,expSolution))

%% Test single class
expSolution = 'single';
actSolution = ones('single');
assert(isa(actSolution,expSolution))

%% Test uint16 class
expSolution = 'uint16';
actSolution = ones('uint16');
assert(isa(actSolution,expSolution))

%% Test that fails
assert(false==true);

%% Another test that fails
assert(strcmp('correlation','causation'))

Create a file named ClassBasedTest.m containing the following test class. The class includes a failing test that, with parameterization, results in nine failed test results.

classdef ClassBasedTest < matlab.unittest.TestCase
    properties (ClassSetupParameter)
        generator = {'twister','combRecursive','multFibonacci'};
    end
    properties (MethodSetupParameter)
        seed = {0,123,4294967295};
    end
    properties (TestParameter)
        dim1 = struct('small',1,'medium',2,'large',3);
        dim2 = struct('small',2,'medium',3,'large',4);
        dim3 = struct('small',3,'medium',4,'large',5);
        type = {'single','double'};
    end
    methods (TestClassSetup)
        function ClassSetup(testCase,generator)
            orig = rng;
            testCase.addTeardown(@rng,orig)
            rng(0, generator)
        end
    end
    methods (TestMethodSetup)
        function MethodSetup(testCase,seed)
            orig = rng;
            testCase.addTeardown(@rng,orig)
            rng(seed)
        end
    end
    methods (Test, ParameterCombination='sequential')
        function testSize(testCase,dim1,dim2,dim3)
            testCase.verifySize(rand(dim1,dim2,dim3),[dim1 dim2 dim3])
        end 
    end
    methods (Test, ParameterCombination='pairwise')
        function testRepeatable(testCase,dim1,dim2,dim3)
            state = rng;
            firstRun = rand(dim1,dim2,dim3);
            rng(state)
            secondRun = rand(dim1,dim2,dim3);
            testCase.verifyEqual(firstRun,secondRun);
        end
    end
    methods (Test)
        function testClass(testCase,dim1,dim2,type)
            testCase.verifyClass(rand(dim1,dim2,type),type)
        end
    end
end

At the command prompt, create a test suite from both test files.

import matlab.unittest.TestRunner;
import matlab.unittest.TestSuite;
import matlab.unittest.plugins.TestReportPlugin;

suite = testsuite({'ScriptBasedTest','ClassBasedTest'})
suite = 

  1×284 Test array with properties:

    Name
    ProcedureName
    TestClass
    BaseFolder
    Parameterization
    SharedTestFixtures
    Tags

Tests Include:
   17 Unique Parameterizations, 0 Shared Test Fixture Classes, 0 Tags.

Create a silent test runner, so that there is no information output to the command window. Create a TestReportPlugin that sends output to the file MyTestReport.docx.

runner = TestRunner.withNoPlugins;
docxFile = 'MyTestReport.docx';
plugin = TestReportPlugin.producingDOCX(docxFile);

Add the plugin to the TestRunner and run the suite.

runner.addPlugin(plugin);
result = runner.run(suite)

open(docxFile)

Create a test suite from a function-based test, run the suite, and generate a report of the results. Include passing diagnostics and the text output to the Command Window.

Create a new file in your working folder named FunctionBasedTest.m containing the following function-based test. The test file includes two failing tests.

%% Main function to generate tests
function tests = FunctionBasedTest
tests = functiontests(localfunctions);
end

%% Test Functions
function passingTest(testCase)
actSolution = 13*3+7*5;
expSolution = 74;
verifyEqual(testCase,actSolution,expSolution)
end

function failingTest(testCase)
actSolution = single(1);
verifyTrue(testCase,actSolution)
end

function anotherPassingTest(testCase)
verifyClass(testCase,string('some text'),'string')
end

function anotherFailingTest(testCase)
verifyTrue(testCase,strcmp('42','everything'))
end

At the command prompt, create a test suite from FunctionBasedTest.m. Create a test runner that displays output to the command window using the default plugin.

import matlab.unittest.TestRunner;
import matlab.unittest.TestSuite;
import matlab.unittest.plugins.TestReportPlugin;

suite = testsuite('FunctionBasedTest');
runner = TestRunner.withTextOutput;

Create a TestReportPlugin that sends output to the file MyTestReport2.pdf. Include passing diagnostics and text output from the Command Window in the report.

pdfFile = 'MyTestReport2.pdf';
plugin = TestReportPlugin.producingPDF(pdfFile,...
    'IncludingPassingDiagnostics',true,'IncludingCommandWindowText',true);

Add the plugin to the TestRunner and run the suite.

runner.addPlugin(plugin);
result = runner.run(suite);

In a file in your current working folder, create the FigurePropTest test class. If the failingTest test method fails (it always does in this example), it uses a FigureDiagnostic to save the figure so you can examine it later.

classdef FigurePropTest < matlab.unittest.TestCase
    properties
        TestFigure
    end
    methods(TestMethodSetup)
        function createFigure(testCase)
            testCase.TestFigure = figure;
        end
    end
    methods(TestMethodTeardown)
        function closeFigure(testCase)
            close(testCase.TestFigure)
        end
    end
    methods(Test)
        function defaultCurrentPoint(testCase)
            cp = testCase.TestFigure.CurrentPoint;
            testCase.verifyEqual(cp,[0 0], ...
                'Default current point is incorrect')
        end
        function defaultCurrentObject(testCase)
            import matlab.unittest.constraints.IsEmpty
            co = testCase.TestFigure.CurrentObject;
            testCase.verifyThat(co,IsEmpty, ...
                'Default current object should be empty')
        end
        function failingTest(testCase)
            import matlab.unittest.diagnostics.FigureDiagnostic
            fig = testCase.TestFigure;
            ax = axes(fig);
            surf(ax,peaks)
            testCase.verifyEmpty(testCase.TestFigure.Children, ...
                FigureDiagnostic(testCase.TestFigure))
        end
    end
end

At the command prompt, create a test suite.

suite = testsuite('FigurePropTest');

Create a silent test runner that records diagnostics and generates a PDF report.

import matlab.unittest.plugins.DiagnosticsRecordingPlugin
import matlab.unittest.plugins.TestReportPlugin
runner = matlab.unittest.TestRunner.withNoPlugins;
runner.addPlugin(DiagnosticsRecordingPlugin);
runner.addPlugin(TestReportPlugin.producingPDF('MyTestReport.pdf'));

Change the default artifact root to your current working folder.

runner.ArtifactsRootFolder = pwd;

Run the tests. The third test fails.
