Class: matlabtest.compiler.TestCase
Namespace: matlabtest.compiler

Generate deployed code artifacts in equivalence tests

Since R2023a

Description

example

buildResults = build(testCase,functionsToDeploy,artifactType) builds the deployed code artifact by using MATLAB® Compiler SDK™ with the type artifactType from the MATLAB functions functionsToDeploy in the equivalence test case testCase.

example

buildResults = build(testCase,buildOptions) builds the deployed code artifact with the options and type specified by buildOptions.

example

buildResults = build(___,PreservingOnFailure=true) preserves the build folder and its contents after a test failure.

Input Arguments

Test case, specified as a matlabtest.compiler.TestCase object.

Files implementing MATLAB functions, specified as a string scalar, a string array, a character vector, or a cell array of character vectors. File paths can be relative to the current working directory or absolute. Files must have a .m extension.

Example: "makesquare.m"

Example: ["makesquare.m","myadd.m"]

Artifact type to build, specified as "dotNETAssembly", "javaPackage", "pythonPackage", or "productionServerArchive".

Build options, specified as one of these objects:

Output Arguments

Build results, returned as a compiler.build.Results (MATLAB Compiler SDK) object.

This example shows how to generate a Python® package from MATLAB source code and test for equivalence by using MATLAB Compiler SDK.

The function makesquare generates an n-by-n matrix:

function y = makesquare(x)
y = magic(x);
end

This class definition file defines an equivalence test case that inherits from matlabtest.compiler.TestCase. The test case in the methods block defines a test case that:

  1. Builds the Python package from the makesquare function

  2. Executes the Python package with input set to 5

  3. Verifies the execution of the Python package against the execution of the MATLAB function makesquare with the same input

classdef tDeployment < matlabtest.compiler.TestCase
    methods(Test)
        function pythonEquivalence(testCase)
            buildResults = build(testCase,"makesquare.m", ...
                "pythonPackage");
            executionResults = execute(testCase,buildResults,{5});
            verifyExecutionMatchesMATLAB(testCase,executionResults);
        end
    end
end

Run the pythonEquivalence test.

This example shows how to generate a Python package with additional build options from MATLAB source code and test for equivalence by using MATLAB Compiler SDK.

The function makesquare generates an n-by-n matrix:

function y = makesquare(x)
y = magic(x);
end

This class definition file defines an equivalence test case that inherits from matlabtest.compiler.TestCase. The test case in the methods block defines a test case that:

  1. Defines a compiler.build.PythonPackageOptions (MATLAB Compiler SDK) object that specifies the function to deploy, the package name, and provides additional files to include in the package

  2. Builds the Python package from the build options object

  3. Executes the Python package with input set to 5

  4. Verifies the execution of the Python package against the execution of the MATLAB function makesquare with the same input

classdef tDeployment < matlabtest.compiler.TestCase
    methods(Test)
        function pythonEquivalence(testCase)

            buildOpts = compiler.build.PythonPackageOptions( ...
                "makesquare.m");
            buildOpts.PackageName = "PackageUnderTest";
            buildOpts.AdditionalFiles = "makesquareData.mat";

            buildResults = build(testCase,buildOpts);
            executionResults = execute(testCase,buildResults,{5});
            verifyExecutionMatchesMATLAB(testCase,executionResults);
        end
    end
end

This example shows how to generate a Python package from MATLAB source code and test for equivalence by using MATLAB Compiler SDK.

The function makesquare generates an n-by-n matrix and the function myAdd takes two inputs and adds them together:

function y = makesquare(x)
y = magic(x);
end
function y = myAdd(a,b)
y = a + b;
end

This class definition file:

  • Builds a packaged that contains makesquare and myAdd

  • Saves the build results object if the test fails

  • Verifies the result with an absolute tolerance

classdef tDeployment < matlabtest.compiler.TestCase
    methods(Test)
        function pythonEquivalence(testCase)
            functionsToDeploy = ["makesquare.m","myAdd.m"];
            buildResults = build(testCase,functionsToDeploy, ...
                "pythonPackage",PreservingOnFailure=true);            
            preserveOnFailure=true;
            executionResults = execute(testCase,buildResults,{5}, ...
                "makesquare",PreservingOnFailure=preserveOnFailure);
            verifyExecutionMatchesMATLAB(testCase,executionResults, ...
