🧪 Add test for missing error paths in load_client_config

[jpoehnelt]

🎯 What: The testing gap for load_client_config error paths (missing file, invalid JSON) was addressed by introducing an environment variable override for the config directory.

📊 Coverage: The new test test_load_client_config now covers:

• Missing file error path.
• Invalid JSON format error path.
• Successful configuration load path.

✨ Result: Increased test coverage and ensured that configuration loading handles failures gracefully. The tests use serial_test::serial and a Drop guard to prevent side effects and flakiness.

Summary of Changes

Hello, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the robustness of the client configuration loading mechanism by introducing dedicated tests for various error conditions and successful scenarios. The changes ensure that the application gracefully handles cases where the configuration file is missing or malformed, thereby improving overall stability and reliability.

Highlights

• Enhanced Test Coverage: Added comprehensive tests for the load_client_config function, specifically covering scenarios where the configuration file is missing, contains invalid JSON, and loads successfully.
• Test Environment Control: Introduced an environment variable override (GOOGLE_WORKSPACE_CLI_CONFIG_DIR) for the configuration directory, enabling isolated and controlled testing environments.
• Robust Test Utilities: Implemented an EnvGuard struct utilizing Rust's Drop trait to ensure environment variables are safely set and cleaned up after tests, and used serial_test::serial to prevent test flakiness due to shared state.

Changelog

• .changeset/testing-improvement.md
  • Added a new changeset file.
• src/auth_commands.rs
  • Modified config_dir to allow overriding the configuration directory via an environment variable for testing purposes.
• src/oauth_config.rs
  • Added EnvGuard struct for managing environment variables in tests.
  • Implemented test_load_client_config to test missing file, invalid JSON, and successful config loading.

Code Review

This pull request adds valuable test coverage for error paths in load_client_config, which is a great improvement. The use of an environment variable override for the config directory is a good strategy for testing file-based operations. I've found a couple of critical issues in the new test code that will cause compilation to fail due to use of moved values. I've also suggested a medium-severity improvement to the EnvGuard helper to make it more robust and prevent potential side effects in the test suite. After addressing these points, the PR will be in excellent shape.

Code Review

This pull request adds valuable test coverage for the load_client_config function, specifically for error paths like a missing or invalid configuration file. The use of an environment variable override for the config directory is a good approach for testing file-based operations. The EnvGuard helper is a nice RAII implementation for managing environment variables safely within tests. I've made a couple of suggestions to improve the conciseness and readability of the new test assertions.
