Tested this at: https://github.com/TravisEz13/PowerShell/actions/runs/13077820229

This pull request includes significant updates to the CI/CD pipeline configuration and testing processes, primarily focusing on PowerShell builds and tests. The changes introduce new workflows, modify existing ones, and enhance logging and artifact handling.

CI/CD Pipeline Enhancements:

• New CI Build Workflow:

  • Added a new composite action for CI build in .github/actions/build/ci/action.yml, which includes steps for capturing the environment, setting build names, bootstrapping, building, running xUnit tests, and uploading build artifacts.

• New Test Verification Workflow:

  • Introduced a new composite action for verifying xUnit results in .github/actions/test/verify_xunit/action.yml, which downloads build artifacts, captures the artifacts directory, and tests xUnit results.

• New Windows Test Workflow:

  • Added a new composite action for testing PowerShell on Windows in .github/actions/test/windows/action.yml, which includes steps for capturing the environment, downloading build artifacts, bootstrapping, running tests, converting JUnit to CTRF, and publishing test reports.

Workflow Modifications:

• Auto Assign PR Maintainer:

  • Modified .github/workflows/AssignPrs.yml to trigger on issues instead of pull requests and added a condition to check if the event issue is a pull request. [1] [2]

• Windows CI Workflow:

  • Added a comprehensive Windows CI workflow in .github/workflows/windows-ci.yml to handle build, unelevated and elevated tests, and xUnit test result verification.

Logging and Artifact Handling Enhancements:

• Enhanced Verbose Logging:

  • Improved verbose logging in tools/ci.psm1 by adding detailed logs for importing modules and starting Pester tests with specific output formats. [1] [2] [3] [4] [5] [6]

• Artifact Handling in GitHub Actions:

  • Updated build.psm1 and tools/ci.psm1 to handle artifact uploading and copying in GitHub Actions environments. [1] [2]

These changes collectively enhance the CI/CD pipeline's robustness, improve logging for better debugging, and ensure seamless artifact handling across different environments.
