Github-CI

You can test your code with Octave or Matlab on Github.

To use it, create a YML file in your .github/workflows with the content described in one of the following sections.

Warning

The example shown below is the one we use for the MOxUnit repository and may need some tweaking to work on yours.

Octave

Using the moxunit Github action

There is a "preset" github action will test your code with Ubuntu and Octave.

---
name: CI octave action

# Controls when the action will run. Triggers the workflow on push or pull request
# events but only for the master branch
on:
    push:
        branches: [master]
    pull_request:
        branches: [master]
    workflow_dispatch:

# cancel previous runs on the same branch / PR
concurrency:
    group: ${{ github.workflow }}-${{ github.ref }}
    cancel-in-progress: true

jobs:

    unit-tests:

        runs-on: ubuntu-latest

        steps:
        # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
        -   uses: actions/checkout@v4

        # Use A Github Action to perform tests
        -   name: run unit tests and documentation tests, generate coverage report
            uses: joergbrech/moxunit-action@v1.1
            with:
                tests: tests
                src: MOxUnit
                with_coverage: true
                doc_tests: true
                cover_xml_file: coverage.xml

        -   name: Store Coverage report as artifact
            uses: actions/upload-artifact@v4
            with:
                name: coverage_xml_file
                path: coverage.xml

'Manual' set up

If you do not use the github action, you have to install octave and all the relevant toolboxes.

---

Matlab

You can test your code with Matlab with several operating systems and Matlab versions.

Note that this wokflow calls the following script:

% Script used to run tests with github CI

IS_CI = getenv('CI');
if ~IS_CI
    error('This script should only run in continuous integration.');
end

cd('MOxUnit');
moxunit_set_path();
cd ..;
addpath(fullfile(pwd, 'MOcov', 'MOcov'));
moxunit_runtests tests -verbose -with_coverage -cover MOxUnit -cover_xml_file coverage.xml;
exit(double(~ans));

Warning

You may need to use a slightly different run_tests_gh_ci.m by updating the values for path/to/src and path/to/tests to make sure it points to where your source code and tests are.

cd('./MOxUnit/MOxUnit/');
moxunit_set_path();
cd ../..;

addpath(fullfile(pwd, 'MOcov', 'MOcov'));

moxunit_runtests path/to/tests -verbose -with_coverage -cover path/to/src -cover_xml_file coverage.xml;

exit(double(~ans))
