Verify Azure DevOps Org and PAT are set when link-commits-to-pull-request is true

[Copilot]

Problem

When link-commits-to-pull-request is set to true, the action attempts to link work items to pull requests using Azure DevOps APIs. However, if the required azure-devops-organization or azure-devops-token inputs are not provided, the action would proceed to call the Node.js script and fail with a cryptic error later in the process.

The code had a TODO comment indicating this validation was needed:

# TODO: check to see if org/pat are set

Solution

Added validation checks before attempting to link work items that verify both Azure DevOps configuration values are set. The validation:

1. Checks each input separately - First validates azure-devops-organization, then azure-devops-token
2. Provides specific error messages - Each check has a clear error message indicating exactly which configuration is missing:
   • "Azure DevOps organization is required when link-commits-to-pull-request is true"
   • "Azure DevOps token is required when link-commits-to-pull-request is true"
3. Fails early - The action exits immediately (exit 1) with a GitHub Actions error annotation before attempting API calls

Example

If a user configures the action with link-commits-to-pull-request: true but forgets to set the organization:

Before: The action would fail later with a cryptic error about Azure DevOps API calls failing

After: The action fails immediately with:

::error title=Missing Azure DevOps Configuration::Azure DevOps organization is required when link-commits-to-pull-request is true

Testing

Added comprehensive test coverage in __tests__/action.test.sh:

• ✅ Validation passes when both org and PAT are set
• ✅ Validation fails when org is empty
• ✅ Validation fails when PAT is empty
• ✅ Validation fails when both are empty

All 29 bash tests and 3 JavaScript tests pass with no regressions.

Fixes the TODO comment and improves user experience by providing clear, actionable error messages early in the workflow execution.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• dev.azure.com
  • Triggering command: node /home/REDACTED/work/azdo_commit_message_validator/azdo_commit_message_validator/node_modules/.bin/jest (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
