-## Unit Tests
-
-Unit tests for `ConfigManager` are implemented in `src/g2_2025_grade_calculator_pkg/test/ConfigManager.test.cpp` using Google Test and ROS2 test utilities. The tests use temporary TOML files to validate configuration loading and parsing functionality.
-
-### Test Cases
-
-#### 1. ConstructorTest
-
-**Description:** Verifies that ConfigManager can be created with a ROS2 logger without crashing.
-
-- **Test Action:** Create ConfigManager instance with ROS2 logger
-- **Expected Result:** Instance created successfully without exceptions
-
-#### 2. LoadValidConfigTest
-
-**Description:** Tests loading of valid TOML configuration files with proper parsing.
-
-- **Test Action:**
-  - Create temporary TOML file with valid configuration
-  - Call `load_config()` with file path
-- **Expected Result:**
-  - Returns `true`
-  - `is_loaded()` returns `true`
-
-#### 3. LoadInvalidFileTest
-
-**Description:** Tests error handling when attempting to load non-existent configuration files.
-
-- **Test Action:** Call `load_config()` with non-existent file path
-- **Expected Result:**
-  - Returns `false`
-  - `is_loaded()` returns `false`
-
-#### 4. DatabaseConfigParsingTest
-
-**Description:** Tests complete database configuration parsing with all parameters.
-
-- **Test Configuration:**
-  ```toml
-  [database]
-  host = "test_host"
-  port = 1234
-  dbname = "test_db"
-  user = "test_user"
-  password = "test_password"
-  timeout = 60
-  ssl = true
-
-  [database.pool]
-  min_connections = 2
-  max_connections = 20
-  ```
-- **Expected Result:** All configuration values parsed correctly with proper types
-
-#### 5. DatabaseConfigWithoutPoolTest
-
-**Description:** Tests default values when optional pool section is missing from configuration.
-
-- **Test Configuration:**
-  ```toml
-  [database]
-  host = "localhost"
-  port = 5432
-  dbname = "grades"
-  user = "postgres"
-  password = "postgres"
-  ```
-- **Expected Result:**
-  - Main database config parsed correctly
-  - Default pool values: `min_connections = 1`, `max_connections = 10`
-
-#### 6. GetConfigWithoutLoadingTest
-
-**Description:** Tests behavior when attempting to access configuration before loading any file.
-
-- **Test Action:** Call `get_database_config()` without loading configuration
-- **Expected Result:**
-  - Returns `std::nullopt`
-  - `is_loaded()` returns `false`

-## Unit Tests
-
-Unit tests for `DatabaseManager` are implemented in `src/g2_2025_grade_calculator_pkg/test/DatabaseManager.test.cpp` using Google Test and ROS2 test utilities. The tests are designed to work reliably whether a database connection is available or not, focusing on error handling and method behavior validation.
-
-### Test Cases
-
-#### 1. ConstructorTest
-
-**Description:** Verifies that DatabaseManager can be created without crashing and proper initialization occurs.
-
-- **Test Action:** Create DatabaseManager instance with ROS2 logger
-- **Expected Result:** Instance created successfully without exceptions
-
-#### 2. ConnectionStatusTest
-
-**Description:** Tests that the `is_connected()` method returns a valid boolean value.
-
-- **Test Action:** Call `is_connected()` method
-- **Expected Result:** Returns either `true` or `false` (no crashes or invalid states)
-
-#### 3. QueuePendingCombinationsTest
-
-**Description:** Verifies retrieval of pending student-course combinations that need exam results.
-
-- **Test Action:** Call `queue_pending_combinations()`
-- **Expected Result:** Returns valid vector (empty if no database connection, populated if connected)
-
-#### 4. StoreExamResultTest
-
-**Description:** Tests exam result storage with graceful handling of connection states.
-
-- **Test Action:**
-  - Student: `"TestStudent"`
-  - Course: `"TestCourse"`
-  - Grade: `85`
-- **Expected Result:** Returns `false` if no connection, `true` if connected and successful
-
-#### 5. EnrollStudentTest
-
-**Description:** Tests student enrollment into courses.
-
-- **Test Action:**
-  - StudentCourse object with test data
-- **Expected Result:** Returns `false` if no connection, `true` if connected and successful
-
-#### 6. GetFinalGradeTest
-
-**Description:** Tests final grade retrieval for non-existent student-course combinations.
-
-- **Test Action:**
-  - Student: `"NonExistentStudent"`
-  - Course: `"NonExistentCourse"`
-- **Expected Result:** Returns `-1` (no results found or no connection)
-
-#### 7. StoreFinalResultTest
-
-**Description:** Tests storing calculated final course results.
-
-- **Test Action:**
-  - StudentCourse object
-  - Exam count: `3`
-  - Final grade: `75`
-- **Expected Result:** Returns `false` if no connection, `true` if connected and successful
