matlabtest.compiler.TestCase - Test case for deployed code artifact equivalence tests - MATLAB (original) (raw)

Superclasses: matlab.unittest.TestCase

Test case for deployed code artifact equivalence tests

Since R2023a

Description

Use the matlabtest.compiler.TestCase class to generate and test MATLAB® Compiler SDK™ deployed code artifacts for equivalence with MATLAB source code. Running equivalence tests for deployed code artifacts requires MATLAB Compiler SDK. This class inherits from matlab.unittest.TestCase.

The matlabtest.compiler.TestCase class is a handle class.

Creation

Create a class definition file that inherits from matlabtest.compiler.TestCase. Author test methods in a methods block to define the test case.

Examples

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.

Limitations

• You cannot run tests that inherit from matlabtest.compiler.TestCase with parallel execution.
• You cannot generate deployed code artifacts or test them for equivalence in MATLAB Online™.
