🤖 test: add Ollama integration tests with CI support

ammar-agent · ammar-agent · commit 9021ffd06e74 · 2025-11-08T01:52:57.000Z
Adds comprehensive integration tests for Ollama provider to verify tool
calling and file operations work correctly with local models.

Changes:
- Add tests/ipcMain/ollama.test.ts with 4 test cases:
  * Basic message sending and response
  * Tool calling with bash tool (gpt-oss:20b)
  * File operations with file_read tool
  * Error handling when Ollama is not running
- Update setupWorkspace() to handle Ollama (no API key required)
- Update setupProviders() type signature for optional baseUrl
- Add Ollama installation and model pulling to CI workflow
- Configure CI to run Ollama tests with gpt-oss:20b model

The tests verify that Ollama can:
- Send messages and receive streaming responses
- Execute bash commands via tool calling
- Read files using the file_read tool
- Handle connection errors gracefully

CI Setup:
- Installs Ollama via official install script
- Pulls gpt-oss:20b model for tests
- Waits for Ollama service to be ready before running tests
- Sets OLLAMA_BASE_URL environment variable for tests
