refactor: improve test isolation using TempDir utility#1578
Conversation
1. Replaced manual file cleanup in test setup/teardown with TempDir utility 2. Removed global helper functions for temporary file paths 3. Moved lock file and version file creation to individual test cases 4. Added proper TempDir header inclusion 5. Each test now creates its own isolated temporary directory This change improves test isolation by ensuring each test case has its own clean temporary environment, eliminating potential interference between tests. The TempDir utility automatically handles directory creation and cleanup, making the tests more robust and maintainable. Influence: 1. Verify all test cases still pass individually and collectively 2. Confirm no file conflicts occur when running tests in parallel 3. Check that temporary files are properly cleaned up after test execution 4. Ensure test isolation prevents cross-test contamination refactor: 使用 TempDir 工具改进测试隔离性 1. 使用 TempDir 工具替代测试设置/清理中的手动文件清理 2. 移除了用于临时文件路径的全局辅助函数 3. 将锁文件和版本文件创建移至各个测试用例中 4. 添加了正确的 TempDir 头文件包含 5. 每个测试现在创建自己独立的临时目录 此更改通过确保每个测试用例都有自己干净的临时环境来提高测试隔离性， 消除了测试之间潜在的干扰。TempDir 工具自动处理目录创建和清理， 使测试更加健壮和可维护。 Influence: 1. 验证所有测试用例单独和集体运行时仍然通过 2. 确认并行运行测试时不会发生文件冲突 3. 检查测试执行后临时文件是否正确清理 4. 确保测试隔离性防止跨测试污染

Code Review
This pull request is a great step towards improving test isolation by using the TempDir utility. The changes correctly refactor most of the tests to create their own temporary environments, which is a significant improvement for test robustness and maintainability. However, I've found one test case, CreatesDirectoryForLockFile in application_singleton_test.cpp, where the refactoring is incomplete. It introduces a TempDir instance but doesn't use it, continuing to rely on the system's shared temporary directory and manual file cleanup. This oversight undermines the goal of complete test isolation. My review comment provides details on this issue. Once this is addressed, the PR will be in excellent shape.

The temp_dir and lockFilePath variables are unused in this test. The test logic continues to use std::filesystem::temp_directory_path() directly and performs manual cleanup, which goes against the goal of this refactoring for better test isolation. This test should be updated to use the temp_dir to construct its paths and rely on RAII for cleanup, making it consistent with other tests in this file.
