testsuite

Create suite of tests

Syntax

suite = testsuite

suite = testsuite(tests)

suite = testsuite(tests,Name,Value)

Description

suite = testsuite creates a suite of tests from your current folder, and returns the suite as a Test array.

To run a test suite created with testsuite, use the run method of matlab.unittest.TestSuite, matlab.unittest.TestRunner, or matlab.perftest.TimeExperiment.

suite = testsuite(tests) creates a suite from a set of specified tests.

suite = testsuite(tests,Name,Value) creates a suite of tests with additional options specified by one or more Name,Value pair arguments.

Examples

Test Suite from Working Folder

Create a folder myExample in your current working folder, make it your current working folder, and create a couple of tests.

In the myExample folder, create a script-based test, onesTest.m.

%% Test double class
expClass = 'double';
act = ones;
assert(isa(act,expClass))

%% Test single class
expClass = 'single';
act = ones('single');
assert(isa(act,expClass))

%% Test uint16 class
expClass = 'uint16';
act = ones('uint16');
assert(isa(act,expClass))

%% Test size
expSize = [7 13];
act = ones([7 13]);
assert(isequal(size(act),expSize))

%% Test values
act = ones(42);
assert(unique(act) == 1)

In the myExample folder, create a function-based test, eyeTest.m.

function tests = eyeTest
tests = functiontests(localfunctions);

function doubleClassTest(testCase)
actValue = eye;
verifyClass(testCase,actValue,'double')

function singleClassTest(testCase)
actValue = eye('single');
verifyClass(testCase,actValue,'single')

function uint16ClassTest(testCase)
actValue = eye('uint16');
verifyClass(testCase,actValue,'uint16')

function sizeTest(testCase)
expSize = [7 13];
actValue = eye(expSize);
verifySize(testCase,actValue,expSize);

function valueTest(testCase)
actValue = eye(42);
verifyEqual(testCase,unique(diag(actValue)),1)    % diagonal are 1s
verifyEqual(testCase,unique(triu(actValue,1)),0)  % upper tri vals are 0
verifyEqual(testCase,unique(tril(actValue,-1)),0) % lower tri vals are 0

Create a test suite from all tests in the current folder.

suite = testsuite

suite = 

  1×10 Test array with properties:

    Name
    BaseFolder
    ProcedureName
    SharedTestFixtures
    Parameterization
    Tags

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

If onesTest and eyesTest are the only tests in your folder, MATLAB^® creates a suite of 10 tests.

View the names of the tests in suite.

{suite.Name}'

ans = 

    'eyeTest/doubleClassTest'
    'eyeTest/singleClassTest'
    'eyeTest/uint16ClassTest'
    'eyeTest/sizeTest'
    'eyeTest/valueTest'
    'onesTest/TestDoubleClass'
    'onesTest/TestSingleClass'
    'onesTest/TestUint16Class'
    'onesTest/TestSize'
    'onesTest/TestValues'

Create a test suite from all tests in eyeTest.

suite2 = testsuite('eyeTest')

suite2 = 

  1×5 Test array with properties:

    Name
    BaseFolder
    ProcedureName
    SharedTestFixtures
    Parameterization
    Tags

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

Test Suite from Select Tests

In your working folder, create a class-based test, testZeros.m. This class contains five test methods.

classdef testZeros < matlab.unittest.TestCase
    properties (TestParameter)
        type = {'single','double','uint16'};
        outSize = struct('s2d',[3 3], 's3d',[2 5 4]);
    end
    
    methods (Test)
        function testClass(testCase, type, outSize)
            testCase.verifyClass(zeros(outSize,type), type);
        end
        
        function testSize(testCase, outSize)
            testCase.verifySize(zeros(outSize), outSize);
        end
        
        function testDefaultClass(testCase)
            testCase.verifyClass(zeros, 'double');
        end
        function testDefaultSize(testCase)
            testCase.verifySize(zeros, [1 1]);
        end
        
        function testDefaultValue(testCase)
            testCase.verifyEqual(zeros,0);
        end
    end
end

The full test suite has 11 test elements: 6 from the testClass method, 2 from the testSize method, and 1 each from the testDefaultClass, testDefaultSize, and testDefaultValue methods.

Create a test suite from the test elements with test names that contain 'Default'.

suite = testsuite('testZeros','Name','*Default*')

suite = 

  1x3 Test array with properties:

    Name
    ProcedureName
    TestClass
    BaseFolder
    Parameterization
    SharedTestFixtures
    Tags

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

Create a test suite from the test elements that use the outSize parameter property.

suite = testsuite('testZeros','ParameterProperty','outSize')

suite = 

  1x8 Test array with properties:

    Name
    ProcedureName
    TestClass
    BaseFolder
    Parameterization
    SharedTestFixtures
    Tags

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

The test suite contains eight tests that use the outSize parameter property: six from the testClass method and two from the testSize method.

Input Arguments

tests — Array of tests

character vector | cell array of character vectors

Suite of tests specified as a character vector or cell array of character vectors. Each character vector in the cell array can contain the name of a test file, a test class, a test suite element name, a package containing your test classes, or a folder containing your test files.

Example: testsuite('ATestFile.m')

Example: testsuite('ATestFile/aTest')

Example: testsuite('mypackage.MyTestClass')

Example: testsuite(pwd)

Example: testsuite({'mypackage.MyTestClass','ATestFile.m',pwd,'mypackage.subpackage'})

Name-Value Pair Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside single quotes (' '). You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: suite = testsuite(tests,'Name','productA_*') creates a test suite from tests that have names starting with 'productA_'.

'BaseFolder' — Name of base folder

character vector

Name of the folder that contains the file defining the test class, function, or script, specified as a character vector. This argument filters TestSuite array elements. To include a test element in the suite, the specified base folder must contain that test element. Use the wildcard character, *, to match any number of characters. Use the question mark character, ?, to match a single character. For test files defined in packages, the base folder is the parent of the top-level package folder.

'IncludeSubfolders' — Indicator to include tests in subfolders

false (default) | true | 0 | 1

Indicator to include tests in subfolders in the suite, specified as false or true (0 or 1). By default the framework creates a suite from tests in the specified folders and not in their subfolders.

Data Types: logical

'IncludeSubpackages' — Indicator to include tests in subpackages

false (default) | true | 0 | 1

Indicator to include tests in subpackages in the suite, specified as false or true (0 or 1). By default the framework creates a suite from tests in the specified package and not in their subpackages.

Data Types: logical

'Name' — Name of suite element

character vector

Name of the suite element, specified as a character vector. This argument filters TestSuite array elements. For the testing framework to include a test in the suite, the Name property of the test element must match the specified name. Use the wildcard character, *, to match any number of characters. Use the question mark character, ?, to match a single character.

'ParameterName' — Name of parameter

character vector

Name of a parameter used by the test suite element, specified as a character vector. This argument filters TestSuite array elements. Use the wildcard character, *, to match any number of characters. Use the question mark character, ?, to match a single character.

'ParameterProperty' — Name of parameterization property

character vector

Name of a property that defines a parameter used by the test suite element, specified as a character vector. This argument filters TestSuite array elements. Use the wildcard character, *, to match any number of characters. Use the question mark character, ?, to match a single character.

'ProcedureName' — Name of the test procedure in the test

character vector

Name of test procedure, specified as a character vector. This argument filters TestSuite array elements. Use the wildcard character, *, to match any number of characters. Use the question mark character, ?, to match to exactly one character.

In a class-based test, the ProcedureName is the name of the test method. In a function-based, test it is the name of the local function that contains the test. In a script-based test, it is a name generated from the test section title. Unlike Name, the name of the test procedure does not include any class or package name or information about parameterization.

'Superclass' — Name of a class that the test class derives from

character vector | string scalar

Name of a class that the test class derives from, specified as a character vector or string scalar. This argument filters TestSuite array elements.

'Tag' — Name of test element tag

character vector | string scalar

Name of test element tag, specified as a character vector or string scalar. This argument filters TestSuite array elements. Use the wildcard character, *, to match any number of characters. Use the question mark character, ?, to match to exactly one character.

Tips

• If you do not need to create a test suite explicitly, use runtests or runperf to create the suite implicitly before running the tests.

• An alternative way to create an explicit test suite is to use the matlab.unittest.TestSuite methods.
