Installing the dotnet-test Plugin

The dotnet-test plugin must be loaded before the upgrade can generate a test baseline. Ask whether the user wants to install it. If they decline, treat Test Coverage as Skip.

{{#if CopilotCli}} Run:

copilot plugin marketplace add dotnet/skills
copilot plugin install dotnet-test@dotnet-agent-skills

Then ask the user to restart the session (/restart or relaunch copilot) and re-run the upgrade. Do not create test-baseline tasks in the current run because the plugin loads only after restart. {{/if}}

{{#if VsCode}} Ask the user to run Chat: Install Plugin From Source from the Command Palette and enter:

https://github.com/dotnet/skills

When VS Code shows the plugins available from that source, ask the user to select dotnet-test.

Alternatively, add dotnet/skills to chat.plugins.marketplaces, then ask the user to install dotnet-test from the @agentPlugins Extensions view. After installation, ask the user to continue the current upgrade. Re-check that code-testing-generator is available, then resume planning. {{/if}}

{{#if GitHubCopilotApp}} Ask the user to open Settings → Plugins or use the Extensions menu in the GitHub Copilot App, find the dotnet-test plugin from dotnet/skills, and install it. Then ask the user to continue the current upgrade. Re-check that code-testing-generator is available before resuming planning. {{/if}}
