- * REFACTORING SUGGESTION:
- *
- * To properly mock std::filesystem::exists in your handler.cpp, consider:
- *
- * 1. Create a filesystem wrapper interface:
- *    class IFilesystemWrapper {
- *    public:
- *        virtual bool exists(const std::filesystem::path& path) const = 0;
- *        virtual std::string read_file(const std::filesystem::path& path) const
- * = 0;
- *    };
- *
- * 2. Modify process() function to accept the wrapper:
- *    std::string process(const std::string& username,
- *                       const IFilesystemWrapper& fs =
- * RealFilesystemWrapper{});
- *
- * 3. Use dependency injection in tests:
- *    MockFilesystemWrapper mock_fs;
- *    EXPECT_CALL(mock_fs, exists(_)).WillOnce(Return(true));
- *    std::string result = process("testuser", mock_fs);
