Use MATLAB with Codecov

This example shows how to run MATLAB® tests, produce code coverage results, and upload the results to Codecov. The repository includes these files.

File Path	Description
source/quadraticSolver.m	A function that solves quadratic equations
tests/SolverTest.m	A class that tests the quadraticSolver function
runMyTests.m	A script that creates a test suite and a test runner that produces code coverage results in Cobertura XML format
azure-pipelines.yml	A configuration example for Azure® DevOps
.circleci/config.yml	A configuration example for CircleCI®
.github/workflows/workflow.yml	A configuration example for GitHub® Actions

Produce and Publish Coverage Results

Each of these pipeline definitions does four things:

1. Install the latest MATLAB release on a Linux®-based build agent.
2. Run all MATLAB tests in the root of your repository, including its subfolders.
3. Produce code coverage results in Cobertura XML format for the source folder.
4. Upload the coverage artifact to Codecov.
