Fix coverage.info file path issue in CI workflow

[Copilot]

Problem

The GitHub Actions workflow was failing when trying to upload code coverage to Coveralls with the error:

Error: ENOENT: no such file or directory, open 'ManagedCode.TimeSeries.Tests/coverage.info'

Root Cause

The CoverletOutput parameter in the test command was set to ManagedCode.TimeSeries.Tests/, which caused coverlet to create a nested directory structure. The coverage file was being generated at:

ManagedCode.TimeSeries.Tests/ManagedCode.TimeSeries.Tests/coverage.info

But the workflow was looking for it at:

ManagedCode.TimeSeries.Tests/coverage.info

Solution

Changed the CoverletOutput parameter from ManagedCode.TimeSeries.Tests/ to ./ so that the coverage file is generated directly in the test project directory where the workflow expects it.

Verification

• ✅ .NET 9.0 is already installed and working correctly
• ✅ All tests pass (71 passed, 1 skipped)
• ✅ Coverage file is now generated at the expected location
• ✅ Build succeeds with 0 errors

Fixes the issue where the coveralls action couldn't find the coverage.info file.

Pull Request Overview

This PR fixes a GitHub Actions workflow failure where the Coveralls action couldn't locate the code coverage file due to an incorrect output path configuration. The issue was caused by coverlet creating a nested directory structure when the CoverletOutput parameter included the project directory name.

Key Changes:

• Updated the CoverletOutput parameter in the test command from ManagedCode.TimeSeries.Tests/ to ./ to ensure the coverage file is generated in the expected location
